Lightroom has a new enhancement feature to double the number of pixels along the width and height, resulting in enlarging my 26 MP pictures to 102MP. I wanted to try it to see how far I could push the focal length of my Pentax 20-40mm lens with cropping.
I thought that some of my pictures made in WVa would make good tests due to the amount of fine details in the images; therefore, I used some raw files made at 40mm focal length to test the LR enhancement feature. I then cropped the enhanced image.
The upper images are the originals, and the ones below are the files which were cropped from the enhanced images.
After I tried the raw images I tried the same thing on a jpeg file that I made at home, with an additional enlargement. I used the LR enlargement and then cropped out a section and then used ON1 to enlarge the cropped file up to 3000 x 3000 pixels. The following shows the result.
I also tried the same technique on some images made at 135mm focal length with the 18-135mm lens and I didn’t like the result. I think I will stick with using my Pentax limited lenses, the 40mm and the 20-40mm, and consider getting a longer limited focal length lens.

I’m getting ready to go to the hills and hollers of WVa for a change of pace. I will commence posting when I return if I make any pictures. Forecast is for warm and humid with a good chance of thunderstorms each day. Good thing I have a Pentax WR camera and lens.
This is a jpeg image made with a Pentax K2000 and the 18-55mm kit lens in June 2009. I think it was my first Pentax DSLR camera. I was on a trip with my brother in parts of WVa and VA.
It isn’t obvious (good thing) in these images but I was practicing and trying some different techniques with my K-3 III camera in preparation for an upcoming trip to WVa.
I was using the camera more like a mirrorless camera by using the LCD to compose and adjust exposures while using the “dirty diaper” camera hold.
I was also using the 20-40mm F2.8 limited zoom lens fixed at 30mm focal length. That setting minimizes the length of the lens for walking about and is also an ideal effective 45mm focal length midway between the two extremes of the short zoom lens. I’m learning to like this lens more and more as I use it. It also has a necessary feature for photography in the higher elevation woodlands of WVa. It is a WR lens.
I make pictures almost everyday. When there is nothing else, I make pictures of leaves or clouds. I do this since I like to play with different processing, etc. I don’t always publish them … just occasionally like now.
I took a walk on memorial day with the purpose of seeing if I might want to leave the Pentax 40mm f/2.8 pancake lens on the K-3 III most of the time; i.e., how that effective 60mm focal length works for me. I like it so far. It makes for the most compact, lightest weight, easiest to carry package possible with that camera.
The only issue I have with the lens is that it is not weather resistant so I would have to switch to the 20-40mm WR lens during wet weather. I might make those two lenses my favorites for my walkabouts. The zoom lens is more versatile but is larger and heavier.
You know it is warmer when you see the flies.
Trump’s lying taught me to not believe most of what I see and hear, so I find I need to investigate almost everything. Recently I saw websites that claimed that the Pentax K-3 Mark 3 is too heavy and bulky for street use. I also saw sites that taunted the merits of a Leica Q2 for street photography. Those articles got me thinking about the differences in the size and weight of the two cameras.
Since I don’t have a Leica Q2 to compare directly with the K-3 Mark 3, I went to the website
https://j.mp/3vAOS05 to compare them. Please click on the link and take a look at the relative sizes from all views.
The site shows the comparison with different views that you can choose. It also mentions that the Leica Q2 (which has a fixed lens) weights 734 g and the K-3 III weighs 820 g (without a lens). Adding the weight of the Pentax 40mm pancake lens to the camera, the Pentax with lens weights 835 g. If you look at the topdown view of the two lenses you can see that the Leica with lens (91.9 mm) is deeper than the Pentax even with the pancake lens (88.7 mm). Even adding the lens hood to the Pentax they are still about the same size. And, having the handgrip counteracts the 14% greater weight of the Pentax over the Leica and makes it easier to hold and use.
Basically they are similar in weight and size and the Pentax is easier to hold since it has a great handgrip; but also keep in mind the vastly different capabilities and features of the two cameras as well as the cost differences. If you prefer the 40mm focal length over the Leica’s 28mm and you want the capability of having a camera with interchangeable lenses, you might prefer the Pentax over the Leica as I do, even for no other reason than the ergonomics.
PS. Go back to the comparison site and also compare the K-3 III to the Leica SL2.
Made these this morning when it wasn’t raining. The ones above are of a Cowbird being raised by a compassionate Carnival in our front yard.
I was getting some test images with my new 40mm f/2.8 pancake lens that arrived yesterday when I made these. I never thought I would be using it for bird and flower images.
I hope all of this cool rain doesn’t mean that we will next swing into a hot dry summer.
The image above was made through a window with at a 40mm focal length. I have been making so many images using the end of the 20-40mm zoom lens that I ordered a small prime pancake lens of 40mm to try as a possible small lens to use when I need to keep the weight lower and be more discreet using the Pentax K-3 III camera.
