I decided to keep the Pentax K-5 and I sold all of my remaining micro 4/3 gear: the Panasonic Lumix G3 along with the Panasonic 100 – 300 mm, 45 – 175 mm, 14 – 42 mm, 14 mm, and 20 mm lenses. I had sold all of my Olympus micro 4/3 cameras & lenses earlier. For a while (I hope a long while) I am going to be using my K-5 and my Fuji X100 cameras. In the final decision, the better ergonomics and speed and IQ of the K-5 trumped the lighter weight of the micro 4/3 system.
I plan to keep and use my X100 for inside buildings, low-light events, walking the street, and lightweight travel by airplane … situations where the equivalent fixed 35 mm focal length is sufficient and/or less weight is necessary. I primarily plan to use my K-5 for wildlife, during bad weather, car trips, and other (haven’t decided) uses. The other uses depend upon which lenses I get and whether I have to carry the camera far or for a long time.
The above picture of the Killdeer was taken last evening at a focal length of 300 (effective 450) mm at an ISO of 1600, f/8, 1/400 sec. I ended up cropping the picture quite a bit and I really could have used the effective 600 mm lens that I sold, but I have decided to stick with the maximum effective 450 mm focal length of the Pentax lens that I have. In addition to the Pentax 55 – 300 mm lens, I also have the weather resistant 18 – 55 mm lens.
I plan on taking some lower light pictures with the 18 – 55 mm lens before I decide on whether I need some additional lenses. One major advantage of the Pentax system is the availability of nice small, lightweight, prime lenses. At the moment I am somewhat conflicted whether I need additional lenses for the K-5. I prefer to use one camera and as few lenses as I can, and the K-5 could serve that desire except for the weight issue. I am still afraid that I will have problems with carrying and holding the K-5 with its heavier lenses, and that is why I have and intend to keep a Fuji X100.
I prefer to use the X100 if I’m walking for a long time. If I didn’t have the X100 I could reduce the weight of the K-5 system by putting a prime lens on it, but it would still be around twice as heavy as the X100. The X100 is also a better system when I’m among people and wish to be a little more discreet … and I just love that camera and the hybrid viewfinder. For now I tend to leave the 55 – 300 mm lens on the K-5 and use the X100 if I need a shorter focal length, unless there is a chance of rain. By working that way, I can grab either camera quickly to shoot. I can carry both in a bag but haven’t so far. I just pick up one or the other camera depending on what I expect to be shooting and go bag-less while walking.
