Hi,
Even from my days on working the photo lab, it was hard to get good information, and even here in the metro, Pro Photo would be the place to ask questions, but I noticed that they always lean the answer towards the sale they currently have!
Previously, I learned most of what I got from the folks that distributed the paper and the chemistries from the lab ... I knew from them what people bought and what the results were ... for example ... putting the school pictures on flat paper, sharp paper or the glossy paper, and which film they used ... you could tell easily enough ... kodachrome or ektachrome ... and the like.
The lenses for a camera is not something I got lucky with though I always had a wide-angle macro zoom lens that went 35-220 ... which I bought in Santa Barbara cheap, one time ($200) and used it for 25 years ... it was just a comfortable lens and moved in and out fine ... though moving out ... was too far away! All the pictures I took came through that lens.
In general, I NEVER used the standard cheapo that came with all cameras, and those lenses are crap, and distort the results and what you like to do. or are trying to do.
I do not expect the digital to be any different ... and sure enough ... the same crappy lens, but I'm not finding a good zoom wide angle lens ... as most of those out there are exactly the same thing ... glorified crap, and designed for the straight ahead shot and no periphery!
