Focus Hunting I have used this lens on a Rebel XTi and XSi and experience quite a bit of focus hunting when zoomed out at 70+. Anybody else seeing this? Any fixes?

I used this lens for one year until yesterday without any problems. Just yesterday I am experiencing the same issue: quite focus hunting when zoomed out at 70+ and when it stops it is not on focus! Any idea?

I cleaned my contacts with a eraser like someone suggested and it worked for me.

For me, the lack of accurate focus was why I returned this lens. For many of my shots - nothing was in focus over the whole photo. It may work fine for some, but every iteration of this lens that I tried did not work for me. I recommend looking at the Tamron 10-24 f3.5 (further zoom, better aperture). I've been using it for 1.5 yrs & it stays on my camera as the default lens!

I love it with my canon...image quality is great, wide focus ring is very easy to use for manual focus which I love to do. Short distance focus is fun to use along with the wide angle. Low light is very good...loved using it at dusk in Africa. Husband is a Nikon person and is jealous of the pictures. Take care.

Many say the 75-300 isn't a very good lens but I disagree. I own one and have excellent results with mine. I also own the t3i and it's an excellent camera for both stills and video... now that I have it I won't go to any other... why? The t3i has everything I want in a camera.

Hi, i'm sorry, but i've never used the canon lens. I use the fuji lens on an xt1 but the af is quite slow, it isn't the best quality of the lens.

I have been in Photography for nearly 30 years and I can tell you that there is DEFINITELY a problem with the XSi's auto focus. I have shot over a thousand test shots with this camera and although most of them turned out looking pretty good I noticed a CONSISTENT problem with the auto-focus feature. One thong is that even if you set it to focus only on the center spot it will still occassionally focus on the area closer to you than the focus spot. Actually it is not just occasionally, but nearly every time. I have got so teed off with this persistent problem that I shoot everything that is important to me in manual focus!

Has anyone received an official response from Canon on this issue? Specifically, the nature of the issue (hardware/software). I have the same problem. Autofocus outside of the widest zoom setting does not function. The camera lights up focus targets and beeps, but the focus is clearly wrong. The camera is NOT in macro mode.

I've had absolutely no issues. This is my second most go to lens when shooting portraits. I prefer the 70-200 more, but that's just my style.

I've been reading reviews and have seen complaints from those who have upgraded to Hero 3 that the sharpest focus is about 4' away. It does not focus to infinity as it appears older models did. Does anyone have any feedback on that? We want to have focus at long distance while doing long distance motorcycle touring.

Works great with the 70d. The key to getting great images is the lens. On my 18-135, the results were mediocre. On my 50mm, the results were excellent.

What camera bodies do you currently own and for what type of shooting?? For portrait, people love the 85, some even say they prefer the 100mm. I own the 50L, the only thing I can say is that shooting at f1.2 takes practice, and the auto focus is a bit slower than most other modern day lens with AF.

My EOS-1Ds Mark III arrived about two weeks ago around the first of Dec. Certainly there are no focus problems on any lens I've tried, and I have 8 or 10. In fact, one can "tweak" the focus for each lens. I've not seen the need for this rather technical step, however, and should I, then I'll do it professionally with correct charts, lighting and so on. It can be redone, though, so any errors can be corrected.

This takes a long time to focus, particularly on macro. While trying to get a shot of the super moon, I missed all of them, indoors using zoom is also slow. Without any zoom, much better. I think the zoom is the real culprit. Still with 16 MP per shot you can crop a photo and still have a sweet pix. I tend to do a lot of cropping in PSP. However, on a recent visit with my grandson, I missed nearly all the good shots as it wouldn't focus, some times while shooting a macro shot for example of a ring I made, it can take 20 tries to get a good shot, or twenty tries just to get it to focus, once focused it takes awesome pix. But those missed ones are a bummer. I tried several other cameras with 20x zooms, that didn't work at all in low light, this may not have a mega zoom, but 12x beats those longer zooms all over the place. In outdoor lighting on a cloudy day it does AWESOME. Hope this helps, I brought home a Canon, other Nikons, a Panasonic Lumix, Sony and Samsung they all were worse than this one. So with limited funds this is what I kept. My brother recently bought a Sony that was another $150.00 more dollars, and he got awesome pix of the super moon. If I had the money I'd shell it out for a more expensive camera, my sister just bought the next up from this with a 20x zoom, we both took pictures of the same subjects, mine were much better than hers. She uses a tripod a lot, I Don't want to use a tripod. It's supposed to be point and shoot. More zoom is bot necessarily better. Just my opinions.

This lens for me anyway is fantastic. Love this lens. Nice bokeh. Great quality. Only issue I have is because of the smaller sensor the 50 mm is actually a slight zoom. If I did it again, I would probably look for a quality 35mm lens with the same aperture. I believe I bought this from sunset. Didn't have any issues with them, but that was a while ago already.

My difficulty with using this type of lens is the fine focus adjustment. It was not possible to do on my Canon 60D. Is there any way to adjust the lens?

I'm thinking of getting this lens to take pictures of a performance in a theatre, so low light and no flash. I have a canon rebel xsi and need to know if this will help and what kind of settings I should use. Don't know much about photography...I always use the auto sesttings which generally work great but I want to capture the great moments of my little dancer. Thanks

I've used the Tamron 18-270 for about 3 or 4 years on my Canon XTi and I love it! I can't compare it to a Nikon kit lens. It seems as sharp as my Canon kit lens though. If you can only carry one lens with you, this is the one. I now shoot with a Canon 6D with a 24-105mm Canon lens and it is noticeably sharper than the Tamron, but that may be because the 6D has a full-frame sensor. The Tamron will not fit my full-frame 6D so I can't compare the two lenses on the same camera body.
