Just joined and just switched from canon to Nikon. I had to buy all new lenses when I switched, so I kind of went through this whole thing recently. My 2 cents worth takes a different track, while I would agree the 28 is optically superior to the 24, I went with the 24: one because I bought 20, 24, 35, 50 and 85 primes and two because in my mind, there is a huge difference between a 24 and 28 in how the image looks. The 28 is just not wide enough, nor a big enough jump from the 35. And yes, at times I think I probably should have just gotten a zoom to cover it all. But that 24 is sharp as hell with my 610. So, I guess it just comes down to a bunch of opinions, yes?
