Since getting the Tamron 17-50 F2.8 I've hardly used the nifty fifty either.
Same here. I believe the Tamron 17-50 is sharper too, but the winner for me is how close to the subject you can focus eliminating the need to crop in PP.

what's the point of comparing a 50/1.8 with the 17-55/2.8?
Well, very simply, if you're not going to use the nifty at all, once you have a decent quality lens, why bother buying it at all?
If you want a fast 50mm lens then pass on the 50/1.8 and at least get the 50/1.4. Of course that's a dearer lens, but it's one that will last you years rather than being a 5 minute curiosity. f/1.8 with an AF motor that sucks is not a great recipe for stunning results.
I appreciate that the nifty suits some people very well, but it is not a lens that suits everybody. It's a step up the ladder in IQ from the old 18-55 non-IS kit lens but I started out with the 17-85, which has IS and USM and is pretty sharp at mid to long focal lengths. Almost everything about the 50 was a step backwards from even that humble lens, other than the fast aperture. Namely....
- AF was slower;
- AF was noisier;
- AF was less precise;
- MF very difficult to accomplish accurately;
- Build was poo;
- No IS;
- Huge gap in the focal length range;
- Horrible pentagonal bokeh when stopped down
There are two reasons to get the 50/1.8 - to cope with low light and/or to achieve shallow DOF. Well, since the AF is poor, especially in low light, the reasons for the lens to even exist start to diminish. Shallow DOF with missed focus is not much help either, if you don't have time to get the focus right, or to repeat shots until one has the focus where you need it.
The way to step forward from the 17-85 is with the 17-55 or the 50/1.4, not the 50/1.8. Thus, IMHO the comparison is relevant. People should understand what a short lifespan the nifty might have, should they buy one. If I knew two years ago what I know now I would never have bought it.

No. I'm saying that if one is a photography enthusiast, rather than a casual hobbiest, it is easy to outgrow the limited abilities of the nifty, quite quickly. It would tend to be the case, I would think, that as one's own experience and skill levels increase, one might demand better performance from one's equipment, or require it to deliver results in more demanding conditions.Are you saying there's a reliability issue or a novelty issue that wears off (50 1.8)?
Surely that's more to do with the specific minimum focus distance of a particular lens though?![]()
. I was shooting spring flowers a couple days ago and getting in so close with the Tamron compared to the nifty i just questioned why i should keep it. The nifty would get the same shot but i'd have to crop out 25% of the shot in PP to compare. When shooting stock for Alamy all those megapixels count!
