Anon E. Mouse and dazzajl,
thanks for the reply. I have some follow up questions to your answers.
1. Regarding lenses: I have not had that much time to use this camera and its lenses. That is reason that I was asking. I have used all the primes, that is the 28, 45, 90. They were spectacular. I really enjoyed the simplicity in only having to choose the aperture rather than the focal length as well. The downside is that it takes me quite a while to change lenses. This isn't something that's going to change because I cannot physically change lenses myself. I need my helper to do it. This is because of my handicap (I cannot use my fingers with dexterity). On the other hand, I've recently purchased a used 35-70 Zoom lens. I haven't had all that much time to get used to it but the advantages of the multiple focal length is tempting. I do not like the fact that I miss several apertures on the wide open side. Also, I've noticed that I use these focal length seldomly. In other words, what I'm asking is would you give up the comfort of the zoom lens in terms of focal length and simplicity in exchange for better quality (in my view), several more stops in the aperture department, and the hassle of changing lenses?
2. I'm also deliberating between taking negative film or positive film. I do not run my own lab however I have a professional lab that I trust developed my film. I subsequently scanned my film with my Nikon CoolScan 5000. I'm telling you this so that you know what my workflow is. I really enjoyed projecting my slides however, the greater exposure latitude of negative film is very tempting. What type of film do you use? What suggestions would you have for me?
3. Thanks for the information. I haven't really thought about that. Up until now I have never pushed film. Therefore, I have no experience with the subject.
