I have a 17 mm prime lens for my E-PL5 micro 4/3 system, the newer M. Zuiko17 mm 1:1.8 with the shift feature for manual focusing. In full frame terms, that makes the lens an effective 35 mm in terms of field of view, etc. One of the things I am trying to decide is what lenses work best for me. I am trying this prime lens since it has a classic field of view and many have used this as a walk-about lens, but I have been concerned since I walk out in the open … not on city streets. While out walking with it after our paths had drained from the high water I came across this little dead fish … actually there were several of them. This one is about two inches long. I don’t think I will have any problem using this lens for small objects as long as I can walk up close to them. I am now strongly considering this lens for my walk-about setup, primarily because I love the quality and size of the lens.
If I walk with an effective 35 mm lens, it will mean many changes. My past favorite lens for walking outdoors with my DSLR has been a zoom with an effective focal length of 75 to 300 mm … in other words, a relatively long and heavy lens. If I switch to 35 mm it will require me to make major changes in what and how I photograph, but I haven’t decided yet. I will try a 40 – 150 mm micro 4/3 zoom lens which will give an effective 80 – 300 mm focal length but the micro 4/3 lens is a lot lighter and smaller. If I don’t like it I might change my photography to fit my small camera and a few prime lenses. I like to walk and photograph with a camera and lens that I love. The question is, “will I photograph with a small package in my hand that I love to hold and use, or do I go for a system that gives me more flexibility in what I photograph?”
