So i tried it again.
I moved the target to the living room with the big bay window with lots of natural light coming in. I did single shot and burst in AI servo and AF was pretty much on for 21 shots between the 2 modes.
I moved it back down to the game room with window closed and only lights on. I have all LED bulbs and out of 9 shots it only got focus on 4 the rest where OOF. its lower light down here as well. So not sure if its the lower light or the type of light LED messing with its AF. but like I said my 85 1.8, 70-200, and 24-105 all had perfect focus in game room with LED lights

I had the same problems shooting in my office at home. All the lighting is soft white fluorescent bulbs. The only thing consistent about my copy is that it consistently misses AF at a variety of wider apertures and at various distances. The consistency improves as I stop down, but isn't truly consistent until f/5.6!

I sent mine back for a refund.
I was sitting on the porch with my son and was taking pics of him with it. he was like 5feet away and I would say 40% of the images were completely out of focus and missed badly. He wasnt moving around fast just standing there blowing bubbles. So dont know if it was my copy or what but I dont find that acceptable to miss almost half the shots taken on easy subject in good outdoor light.
it was nice when it hit but that was IF it got focus

Sounds similar to my experience. Either the build quality is inconsistent from copy to copy or the lens is very sensitive to slight manufacturing tolerance differences between between camera bodies.

I'm with you guys on this one! I think some people are too picky, some have unrealistic expectations and forget that it is just a $125 lens (not a $2,000+ lens), some convinced themselves there was something wrong with it and are determined to find something wrong, and some people actually have a bad copy. Hard to tell who is who though.

Just shoot with it. If you are happy with the photos then keep it, if you are not then don't. No need to break out charts and start pixel peeping on a $125 lens to prove it is crap or not.

Not really being picky. I would just like it to auto focus remotely accurately most of the time in indoor light. If I have to stop it down to f/4: or f/5.6 to get consistent AF then what is the point? Possibly I have a bad copy.

Your experience is not the norm. Why not try another one?

Mine seems to be almost as bad as OSXrunner's. Will probably try another copy.

I don't want this to turn into a b**ch thread, but it looks like some are ready to call this STM version the "Iffy Fifty" ;-)a

I test mine beyond reasonable doubt that my MFA is bang-on at -0-

The focus reliability has seemed just fine.

The day I received it - one of the first things I tested was AF in Low Light. Well is struggled mightily. Oh well. Look at the price tag, my mk II does not like low light either.

For those truly getting poor focus consistency - I feel for you. I hope you order another, which would likely/hopefully be from a different batch from your defective copy - and you can report your observations here.

I have to remind myself that shooting at f/2.8 or wider is not easy on my subjects - being flowers subject to wind - typically near or pushing MFD - and - me not using a tripod... So I'm almost asking for a lower keeper rate :-P :lol: ;-)a

I mean no offense... but at $125, I think it's fairly safe to assume that the majority of you who purchased this lens are not professionals. I'm also thinking that this is more of a matter of user error than 'bad copies'.

It has a lot to do with it. You take a group of inexperienced SL1 and Rebel shooters with nifty fifty's shooting at 1.8 for the first time and all kinds of user error comes to mind. I used to blame a lot of my OOF images on gear until I figured out what I was doing wrong. I'm not discrediting all of you with bad copies; just saying, I wouldn't be surprised if many of them may be due to inexperience when shooting with a razor thin DOF.

No need to get snarky. It's just a thought...

I suspect the ratio is rather similar to the 50 1.8 mk II owners. That said, there is no denying its a cracking sharp lens at f/3.5 and smaller apertures. I just sold 4 images tonight - my first income from this new lens.

I saw staggeringly beautiful shots from those shooting with an XSi + 50 1.8 mk II. I'm sure you will agree talent needs to outshine the gear for success.

Well so far there's only two with issues...neither one of them look like new users...

No offense taken but you are incorrect. It is not user error. Perhaps a bad copy or a tolerance issue between lens and bodies. I have been shooting quite a few years now Have several other lenses besides the ones listed in my signature, and three different bodies, and know how to use them all to advantage. 40% of the images from my copy of this lens are not just soft, many are downright blurred even with higher shutter speeds, and often even when stopped down.

I have a Sigma 30mm f/1.4 and have no problems with razor thin DoF. That's the reason I got the new 50 in the first place. A 50mm prime is not a lens I think I'll use that much on a crop body because I think a 30 to 35 mm lens on crop is more versatile since it's similar to 50 mm on FF. However, I wanted to hsve a decent fast 50 in my arsenal when needed. The copy I was sent was not it.

It may be good at f/3.5 (my copy isnt) but I bought this lens to shoot at f/1.8;to f/2.8.my 15-85 mm takes great images stopped down. I don't need a cheap fast 50 for that purpose. My copy doesn't do what I need it to do.

Well so far there's only two with issues...neither one of them look like new users...

And both of us are having significant problems. I checked mine for decentering and back and front focusing and all is in order. The issue is a very inconsistent AF, mostly at f/1.8 to f/2.8, but often up to f/4. By f/5.6 it seems to be pretty accurate most of the time. I've gotten used to the fly by wire manual focusing of STM lenses and can often get sharper results manually than I do with AF on this lens.

I wanted to add a positive note; I just got mine yesterday and it seems fine so far.

I used to have a MK II - it felt like it came out of a Crackerjack box! It hunted for focus all the time and felt like it was going to tear itself apart when it did so! Sold it off and later bought a MK I. That one feels much better but hunts just as much in low light.

I also had a 50mm f1.4 USM for a while but it didn't really do much better in low light. Sold that one off too.

This new, STM version of the 50mm f/1.8 grabs focus WAY better in low light for me so far, and it has been dead-on. I haven't had it long enough to test thoroughly so hopefully I won't have to revise my evaluation, but so far I'm very happy with it.
