As it's a bit quiet in here...
What do people think of the 28mm focal length? There's an interesting discussion in the Fred Miranda thread on the new Sigma 35 and 65mm f2's...
I've never been a really big fan of 28mm as I usually prefer a one lens for just about everything approach and 35/50mm suits me best as it goes back to how it all started for me at the age of 10 with a Kodak Instamatic which has a 43mm f11 lens. 28mm for me gives a bit too much perspective distortion which can be fun but it's not for me for and everyday do it all lens.
I've had some film era 28mm lenses for a while and recently added the Nikon 28mm f2.8 Series E MK2 just out of interest as I'd read that it was one of the worst lenses Nikon ever made (I think it's actually quite good) and then the ai-s again just out of interest as I'd read it was very good (and I think it is.) On the strength of these two I also recently bought a used Sony 28mm f2 just to try and also because I fancied something AF and wider than 35mm for a trip to London. I've been impressed as it's compact and light with fast focus on my ancient A7 and the image quality is IMO good.
I can see the attraction and 28mm is afaik the most used focal length these days due to phones but it's on the edge of what I'd be happy with as a one lens for just about everything. It may be just right for some things though
