Quality Can Grow from Quantity

Should I take pictures like the one above?  From your perspective, probably not, but I’m still trying out my 14 – 150 mm lens on the E-PL2, as well as techniques for carrying them, and learning about converting pictures to B&W; therefore, I have my reasons for shooting most anything.  It’s hard to see it in this small picture (click on it and you can enlarge it several times), but I was trying out the technique of setting the camera to the aperture setting of f/8 and shooting a wide range of subjects to see how much detail the camera captured over a wide range.  In addition, while taking the picture I started thinking about quantity vs. quality.

The first trees to succeed in a new forest are the faster growing softwoods.  They grow easily, out produce the hardwoods, get above the hardwoods, and capture most of the light.  But in time, since they are weaker trees, they succumb to insects, snows, and winds, and fall down and decay and provide nutrients for the other trees.  This enables the persistent, but slower growing hardwood trees to grow and replace the softwood forests with the better hardwoods.

In the days of film most of us wouldn’t have taken many shots like the above due to the cost and work involved in developing and printing.  I imagine that it took those “want-to-be photographers” a while to polish their skills.  With digital pictures we no longer need to hold back.  We can take all the pictures that we wish as we practice, etc. without incurring additional costs; but what about other aspects relative to how many pictures we take.

Professionals take quite a few shots with maybe only one out of a thousand ever getting to the public’s view … it’s often less.  They have a subject in mind before ever going out, and research all aspects of the nature of whatever they will be photographing before they go out.  After they get to where they plan to shoot, they often tend to make dozens of shots from different views, etc.  For example, think about the professional landscape photographers.  They often have quite an investment in getting to wherever they are going to photograph, and after they get there they might wait for days and days until the weather and light are just right.  In fact, many return year after year trying to get the perfect shot of just one scene.

Some hobbyist photographers are what you might call opportunistic photographers.  As time goes by, they photograph various things that they see as they go about their life.  It might be pictures of the family or they might specialize in particular subjects.  If it’s their kids they rarely have much time or are ready to capture the moment as it occurs and so they take fewer pictures.

Vacation photographers come from two different schools.  First we have those who take few pictures since they are always waiting for the perfect scene and opportunity.   The others are those who shoot everything as they see it and then they tend to sort out the good ones after they get home.  These later types are often referred to as “spray & shoot” photographers.  If they stop and think about every picture after they get home and consider what is good and what isn’t so good about each picture, they will learn and their success rate will improve with time.  If not, they satisfy themselves with lots of so-so pictures and lots of rejects.  How they use their pictures after they get home also influences which type of shooter they are.  If they only want to have a few good pictures to show others, they tend to take fewer pictures and give more thought to each shot.  If they intend to make a slide show, or daily journal of the trip, that documents the details of their trip they tend to take a lot more shots.  In either case, these types of photographers take few pictures, if more than one, of whatever they are recording even if they take thousands of pictures per trip.  They get it right the first time or they don’t get a quality shot.

Another type of photographer is the street photographer.  These are photographers who are looking for the few decisive moments that they spot as they travel down the street, through the market, etc.  They usually only get one chance to record the decisive moment but the total number of pictures depends on how observant they are and on how much they go out.

From my perspective, there are really only two types of photographers:  The professionals and the rest who I refer to as “life photographers.”  The life photographers are those who usually don’t specialize on one particular type of subject.  They are out there to record life as it occurs no matter what the place or form.  I’m a life photographer who is still learning, as I think most of my readers are.  For both types of photographers, experience helps and that can only come from taking lots of pictures.  In addition quality is created through continuous and dedicated practice.  So the lesson I have learned is, take lots and lots of pictures but study each and every one of them and learn what technique works best.  If I do this, hopefully the quality will follow.

Travel with Prime and/or Zoom Lenses? … Part 2

In the previous article I addressed the choice based on which focal length you use and whether a single focal length lens might be a better answer.  In this article I would like to talk about the decision from more of a user perspective concentrating on when a prime lens might be a better choice to have on your camera.

From an image quality perspective, a prime lens will almost always be better if you tend to use your zoom lens at either extreme of the zoom range.  The design of zoom lenses are more of a compromise and they generally perform best about 1/3 of the way into the zoom range and worse at the extremes … much worse at the longest zoom range.  In addition, zoom lenses usually have much smaller apertures than primes … at least for us mortals who can’t afford, or carry, a professional F2.8 long zoom.  The small apertures reduce the transmitted light and you have to shoot at a higher ISO setting to achieve reasonable shutter speeds.   This is most important in low light settings inside buildings, etc.   For these reasons, if you want better image quality, the prime is the lens to use.

Another issue relative to selecting a lens is the change in perspective.  It’s really not the focal length but a matter of how far you are away from the subject.  Read the quote below and click on it for a good explanation and demonstration.

“Many will say that focal length also determines the perspective of an image, but strictly speaking, perspective only changes with one’s location relative to their subject. If one tries to achieve the same subjects filling the frame with both a wide angle and telephoto lens, then perspective does indeed change because one is forced to move closer or further from their subject. For these scenarios only, the wide angle lens exaggerates or stretches perspective, whereas the telephoto lens compresses or flattens perspective.”

The main issue is how you wish to view your subject.  With a prime lens it will be consistent, with a zoom lens it will change depending on how much you zoom, and it always depends on how far away you are from your subject.

Another concern is changing lenses.  You have to be careful when changing lenses in the field so that you don’t get dirt on the sensor.  The data aren’t really in yet since the cameras are so new, but this might be a larger problem with the mirror-less cameras since when you take the lens off to change it, the sensor is sitting right up front.  Therefore, if you must change focal lengths frequently in a dirty environment, a zoom is probably a better option.

When traveling, I often visit towns & markets where there are a lot of people and I’m essentially “streetshooting”.   When shooting in those environments, I’m not comfortable having a big long lens mounted on a large camera since I think it diminishes my chances of getting candid shots of people.  One recommendation that I have seen is to try to blend in and not look like a professional photographer.  If you are shooting with a small inexpensive looking camera, people seem to pay less attention to you.

Another feature about prime lenses is that they are smaller and easier to carry in a small “non-camera” bag, either when mounted on the camera or carried separately.  I often carry my camera with a prime lens on it in my jacket pocket thus I don’t even need a bag as long as I also have a spare battery and memory card in another pocket.  But I only carry it this way in between areas where I might be taking pictures.  If I’m planning on shooting frequently I carry the camera around my neck or in my hand.  In addition, a couple of prime lenses are usually lighter to carry and if you have been reading my other articles you know that this is a big requirement for me.

If you consider all of the above carefully, you should be in a better position to decide which lenses to take with you on your next trip.  For me, I’m planning on going to Ireland at the beginning of summer and as of now, I’m planning on walking-about during the day with a 14mm prime lens on my micro four-thirds camera and my 14 – 150mm zoom lens in my bag just in case I need it.  In addition I will use my 20mm lens on my camera in the evening or in any low light setting.  (Don’t forget that there is a factor of 2x for converting these to 35mm camera equivalents.)   When I get to wherever I’m going, I can reevaluate the situation and make changes as needed.  As an example, if I were traveling to Costa Rica I would carry the camera with the 14 – 150mm lens mounted on it.  In that location it is more important to have the versatility a zoom represents relative to focal length.

Good luck with your choices.  In the last year I have been drifting more towards using prime lenses rather than zoom lenses for pretty much the same reasons that Nik stated in his comments to an earlier article.  I’ll let you know what I used in Ireland after I return.  At the moment I’m betting on this one … Olympus E-PL2 with the Panasonic 14mm f/2.5 lens, but I still have to take it out and try it in a similar setting.

Travel with Prime and/or Zoom Lenses? … Part 1

When I travel or go anywhere I like to have the right camera and lenses with me.  For me, this means that I have the most discreet and lowest weight system that adequately covers the focal lengths and image quality that I will need.  If you look for recommendations on most travel web sites, they most likely will recommend that you take a zoom lens which has a wide range of focal lengths, usually between 28 and 200mm in 35mm equivalency.  The assumption is that you will then be ready for whatever focal length you might need.  This is the easy recommendation to make but it is probably not the lightest or most discreet camera-lens combination.  In this article I will try to go over some of the more detailed considerations and show how I am approaching making a more refined decision.

To me, making a decision about which lenses to take is similar to hunting with a gun.  You wouldn’t take a deer rifle to go hunting for squirrels or rabbits, so why would you take a large, heavy zoom lens if it is unlikely that you will really need it.  The harder questions to answer are “what focal lengths do you most often use, and what will you need on your next vacation?”

The only way to decide what focal lengths have worked best for you is to review what you have used in similar situations.  Since most of you got a kit zoom lens with your camera when you first bought it, look back through your picture data and see which focal lengths you used the most while taking pictures in a similar situation.  In my situation I have found that I most often use the focal lengths at the extreme ends of the zoom range.  Usually one end or the other depending on the location and type of shooting that I did.  The next decision is to decide whether a prime lens might be better than having the zoom lens mounted on the camera all the time.

To decide whether you like using just one focal length is relatively easy.  Look and see what primes lenses are available for your camera.  Some manufacturers have a wider selection than others but you can usually find one close to the focal length of interest. To test whether you like that focal length, just tape your zoom lens barrel at the focal length that you are considering and try it for a few days while taking pictures in a setting similar to where you will be traveling.  If you like that focal length you can then take the next step and decide whether it is worth acquiring a prime lens in that focal length.

Prime lenses have some advantages, as well as disadvantages, over zoom lenses.  In general, primes are of higher quality, are lighter, and make your camera-lens combination a lot more discreet, but they can be expensive for newer lenses.  You might wish to check out some of the on-line reviewers to see if they have reviewed your lens of interest.  Some that I use are dpreviews.com, m43 Reviews, DxO Mark, LensTip.com, as well as others.

In general you will find that there are two types of reviewers.  Those who measure the technical qualities of the lenses … like the reviewers mentioned above, and then the user reviews which I also find very valuable.  There aren’t as many of them and they typically limit themselves to a narrow range of cameras that they use and prefer.  For cameras of interest to me, there are two that I look at:  Steve Huff Photos, and Soundimageplus.  In all reviews you need to be careful in utilizing the information.  In the technical reviews they often discuss variations between lenses that might not be important in your type of shooting.  In the user reviews you get to see the pictures they took and how well the lens worked for them.  In those cases you don’t know how far away they were when they took the picture nor do you get to see the examples that didn’t work so well.  In the final decision you will need to put the lens on your camera and check it out.

At this point I still wasn’t ready to make a decision, and I doubt you are.  I’ll continue the discussion and get closer to a decision in Part 2 which will follow.

These are the lenses that I’m considering:  Panasonic 14 mm f/2.5 and 20 mm f/ 1.7 (on the E-PL2 camera), and the Olympus 14 – 42 mm f/3.5-5.6 II and 14 – 150 mm f/4-5.6.  They are all great lenses.  I also have the Olympus 17 mm lens which was on my E-P1 camera when I took this picture .  At the moment I’m not considering the 17 mm lens since it is mid-way between the 14 and 20 mm lenses.

Using the Olympus M. Zuiko 14 – 150 mm Lens as a Walk-About Lens on one of the Pen cameras

I ordered the Olympus micro four-thirds 14 – 150 mm zoom lens.  My intent was to evaluate it as a walk-about lens when traveling to places that might warrant the use of a longer focal range.  It is a small, light-weight lens for use on either of my Olympus cameras giving me an effective zoom range between 28 and 300 mm.  I will not repeat the technical details and reviews of this lens on this site, so I suggest that you go to the dpreviews.com site for those details.

Once it arrived, my first desire was to quickly check out how it worked for me so that I could decide whether to keep it; therefore, I put it on my E-P1 and took a walk.  When I got to a small lake near our house I noticed that the surveyors were back and were measuring the depth of the pond.  I expect that they are getting ready to have it dredged since it was designed to filter out the dirt from surrounding construction sites, and it is filling up.

The first picture was taken at the 14 mm end of the zoom … I think it was f/8.  If you look carefully in the center of the picture, you will see a white dot, the surveyor’s paddle boat.  You can click on any of the pictures to view them in a larger size.

The following is the same shot as above but this time I zoomed out to the extreme 150 mm end of the zoom, which is an effective 300 mm on a 35 mm film camera.  You can now see the boat better.

One of my biggest concerns with the lens was the ability to hold it steady enough while shooting at 150 mm.  This is much harder (in my opinion) on these mirror-less cameras which don’t have viewfinders where you have to use the LCD to compose the shot.  This is especially true if you hold the camera out at arm’s-length, but I don’t do that.  I usually keep the neck strap relatively short enough that the strap is tight and my elbows are held firmly against my chest while holding the camera out in front of me.  This creates a triangular support for the camera and is a big help when shooting with a long lens.

The following picture is close to a 100% crop of the above picture.  As you can see, it is a fair, but not great picture.  When shooting this way I am stretching the limits of the camera and lens.  I would expect that the image would be a little sharper if I had used a tripod but since I don’t use one when touring, I tested under the typical conditions that I shoot.  You also have to remember that I’m showing pictures taken at the extremes of the lens where its’ quality isn’t as good (see dpreview.com).

After taking the above shots, I walked on into the wooden area above the lake.  As soon as I entered the woods I heard a hawk so I started looking for it and found it.  The following picture is a quick shot taken at 150 mm.  Since the hawk was a ways off and there were quite a few branches between me and it, the focus isn’t “spot-on”.  I didn’t take the time to focus the lens manually … I just took a quick shot at an aperture setting of 5.6 before it flew off.

The following shows this focus problem, mixed in with the not so great image quality at 150 mm and the fact that I shot quickly.  In this scene I cropped the above picture to get close to a 100% crop just to evaluate the picture and see how well it did, or didn’t do.

I can say that it sure is a lot better than any I have taken with point & shoot cameras under similar conditions, but this lens certainly isn’t a lens for birders.

Another factor that you have to keep in mind when using this lens is the depth-of-field (DoF).  When shooting at f/5.6 with it at something 100 ft. away, the DoF is roughly +/- 10 ft.  If you are shooting something a lot closer it is a lot less.  Shooting something only 10 ft. away, again at f/5.6, the DoF is only roughly +/- 1.3 inches.   The previous as well as the following series of shots demonstrates this.

The next picture was taken at the 14 mm end of the zoom.

I didn’t realize that I was taking a self-portrait … that’s what wider angle lens do for you. The following is the same shot but taken at 150 mm.

I guess that I can best summarize all the above by just saying that I’m keeping the lens.  It certainly isn’t as good as prime lenses but it is typical of most zoom lenses of this range.  I think that, when needed, it will make a great walk-about lens for either my E-P1 or E-PL2 cameras while traveling.  It is also so small and light-weight that I can keep it in my vest or jacket pocket ready to put on the camera if I happen to be using another lens.
