In anticipation of delivery of my Panasonic Lumix GM-5, which I have ordered to facilitate yet another attempt at “street shooting” (HA!HA!), I was perusing reviews of some lenses including the Panny 15mm, f1.7. I just read this review of the Panasonic 15 mm lens and quite honestly I took some exception to it’s assessments of “normal” lenses which the writer has obviously based on the near religious concept that evolved sometime in the early development stages of 35mm SLR cameras. I am not going to argue the points brought out in this article because everyone has their personal feelings and if someone wants to embrace a standard of normalcy set by some previous accepted criteria then so be it. For my personal use, when entering a new format whether it is full frame, APS-C, Micro Four Thirds or the 1/1.7 format, (Check out my CWRailman WEB site to see why I use that format.) I do a bit of experimenting. Whenever I purchase a camera I always get the standard kit zoom lens. (The 12-35 is coming with my GM-5) Yes, it might not be the best but it serves a purpose as it provides me with a lot of different focal lengths to experiment with. For a month or more I shoot my usual subject matter using this lens. (This is a hint for those who like to get on boards like these and ask “What is the best lens for me to shoot with”) After that period of time I sit back and view all of the images that impressed me and check the set focal lengths. What was my most often used focal length? Was it 17mm or 35 or 50 or what? That is what determines what fixed focal length lens, if any, will best suite my particular shooting style with that particular format. And guess what, it’s not the same for all three formats that I am currently shooting. As an example, when shooting 35 film my most often used lens was one of two 35-70 mm lenses that I have. Though I had them, I seldom used my longer focal length lenses and never desired a “wide” angle lens, which was also in my kit, because I really prefer closer more detailed images. The 35-70mm was my choice for my style and my interests. In perusing images shot during that time period it appears that the 45-70 mm range was the most often used. Previously in shooting my Pentax digital APS-C format cameras, a review of my images across many different subjects (excluding the portraits I do for people) shows that my most often used focal length is 30 mm (x 1.5 = 45mm) . Now in shooting my Oly E-M10, 4/3 format my most often used focal length is 18 mm (x2.0 = 36mm). This discovery led to my purchase of a Panny 20mm 1.7 lens which fit into my budget and demonstrated more sharpness than the Oly 17mm lens. While they are close, they really do not agree with the “normal” focal lengths suggested in this article. So maybe I am not “normal” but these are the focal lengths that are comfortable for me and suit my particular shooting style using those formats. Another issue I have found is that shooters automatically assume that a fixed focal length lens (prime for you youngsters) will automatically provide a higher image quality than a variable focal length (zoom) lens. This is NOT true. Check out this comparison of the Panasonic 14-45mm lens and the Oly 17mm lens. You can then shut off the Oly lens and bring up the highly rated Panasonic 20mm lens and see that the 14-45 Panny also gives that a run for it’s money in sharpness. Yes, both these lenses are faster, but again, not everyone has that need. By the way, I should mention that I do not have deep pockets nor believe in using one of those elastic plastic cards to cover my photographic equipment purchases so each purchase is evaluated for relevancy to my needs before taking the plunge.
