I didn't want to post until I'd tested it properly, but I got a Nikkor 50mm f1.8 at the weekend - the original AF model designed for 35mm cameras but working on digital provided they have a motor in the camera body - and it appears to be pretty good - I put my 35mm lens on sale on Sunday because I was already pretty sure the 50mm was OK, and took the 50mm out for a spin today (the weather was crap yesterday). Results were pretty good, I think it's as least as sharp as the 35mm was, and I seem to be able to work much better with it because I can work at a slightly greater distance and it seems to be better for closeup work - I really wish I'd taken extension tubes with me today, it would have been nice to try real macro work, but next time. I've ditched a few duds (mostly of the "did I really cut off the top of that / hold the camera crooked / press the wrong button / move the camera" variety), but still have 45 pictures that seem pretty good out of about 60 I took. I really must look into choosing an optimum ISO setting - I've been using 400 and 800, but if higher speeds will give good results I should really switch to minimize camera shake.
Next step will probably be to sell the Yongnuo 50mm for the Canon - I really don't need it now.
I think, on the whole, that I will keep the 18-55 Nikkor; I don't use it often, but it's the widest lens I own and they aren't selling at huge prices, I might as well keep it.
