B&H has Canon EF 50mm f/1.4 USM for $299. That's very tempting. I have the nifty fifty on crop sensor T2i. Is it really that big of a difference in sharpness?

Dpreview comparison between f/1.8 and f/1.4 (external link) shows there isn't that much of a sharpness difference on crop sensor body. If I read the chart correctly the f/1.8 outperforms f/1.4 from f/3.3 to f/5.6. Did I misread the chart?

Is the upgrade worth it?

I don't think that you will see much of a difference between any of the 50 mm primes from f2.8 to f16. There may be better contrast in the L, but resolution may not be any better, and could be worse in the corners. I don't have the L, so owners can chime in here.
The differences with the F1.8 model will be sharper images at F1.8 for the F1.4 model, and more consistent and accurate AF. The AF alone is probably worth it.
If your F1.8 is sharp wide open, and you are happy with the performance and AF, then why change? If the lens isn't sharp enough for you at F2 and AF is erratic, it could be worth the upgrade.

I'll be honest here and say no! there is no significant difference. I have owned both and maybe I had a super sharp copy of the 50 1.8 ii, but damn it was good! However, I upgraded for the MUCH better autofocus and build quality..well build quality on the 50 1.4 is still not great and it's pretty fragile but it's still better. Another difference is that you don't get as messy of a bokeh with the 50 1.4, no more pentagons in the background. With mine f1.4 is useable and by f2.0 it's very good. Both lenses are extremely sharp at f2.8-f4. The only lens I've used that's sharper is the 35 1.4L. Having said that, if you don't need faster autofocus and are shooting still subjects, don't bother uprading. I swear my 50 1.8 was a little sharper than my 50 1.4.

Thanks artyH. My f/1.8 is a crap shoot when it comes to focusing. I get quite a few soft images (my wife's eyes, where the focus should lock) sometimes when shooting in bright daylight too. I am not sure if my T2i less sensitive focus point (not the center AF) is to blame, my shaky hands or the lens.

Thestructured, I'm with you on that nifty fifty pentagonal bokeh. It doesn't look nice at all. Yes, when my nifty fifty nails the focus, it's razor sharp. Sadly, it misses quite a lot too. Well, according the dpreview chart... f/1.8 is a little sharper than 1.4.

+1 for the 50 1.4. And I've learned to ignore those test and charts. You should rely on your personal opinion. B&H is more than helpful with returns. If you try it and don't like it, send it back. The 1.4 is only an upgrade for certain areas. Now if you feel they are important than you should switch! It is sharper at larger apertures/wide open. If you spend a lot of time there, then you'll see improvement. Also bokeh is significantly better than my old 1.8 II. This may vary but if you like bokeh, the 1.4 will not disappoint. These were the main reasons I switched and was well worth it. By the way, I've had mine for a year so far and have had 0 problems. Good luck!

I just saw bokeh comparison (external link) among 50mm f/1.2 L, f/1.4 and f/1.8. I'm surprised the f/1.4 bokeh isn't perfectly round as I thought it would be. Anyway, I decide not to get this deal.

Does any of you know if Sigma 50mm f/1.4 is a better choice?

I use my 50 1.4 for shooting indoor sports (among other thigns) and it has no problem in servo mode with my 5d mark ii's, I get plenty of sharp, well focused shots. That would have been impossible with the 50 1.8. I was also lucky enough to get mine from canon direct refurbished during a sale, so it was only $255.

I feel that the Sigma bokeh is very similar to the Canon 1.2, so if you liked what you saw of that lens, I think you'd love the Sigma.

I think the sigma is the logical update if you can stand the weight, size and front focus issues. I chose to keep the f1.8 as mine is sharp and focus well enough.


Canon 6D | S35mm f1.4 | 135mm f2 The rest: T3i, 20D, 15mm f2.8, 15-85mm, 24mm f2.8, 50mm f1.8, 85mm f1.8, 90mm f2.8 macro, 55-250mm.
So long and thanks for all the fish

I think those were all shot at 2.8. The 1.4 is rounded up to a certain point.

Sigma 50mm lens looks massive but I've never held one in my hands. I got a Tokina 11-18mm f2.8. Is Sigma 50mm heavier than Tokina 11-16mm f2.8?

dscri001, you have a point. I checked my photo taken at f/1.8, I don't see pentagon shape bokeh. At f3.2, however, the shape becomes a pentagon. I'm keeping my nifty fifty for another year or so.
