Do you get alot of purple or other color fringing with this lens? Or has Tamron fixed that in these newer lenses?

Interesting question, glad you asked. The short answer is no. If there is any I haven't noticed. Having said that, it is a less expensive lens compared to my Canon 100-400mm which I am used to looking at photos with that lens. I am sure I would have seen any purple or color fringing by now. I guess the largest drawback is that it is not tack sharp as its expensive cousin, that is to be expected, but still very good.

I have not noticed any fringing with this lens. It is on my camera daily it seems and is my go to walk around lens.

The portrait problem is real. I just returned a copy of this lens to Amazon because images were very fuzzy in portrait orientation as 300mm was approached. This happened with IS on or off. It seems to be related to mechanical droop of the front barrel which greatly extends as you zoom out. The lens feels cheaply constructed and there is sloopiness in the front barrel. Canon knew about this defect for 9 months but continued to produce these defective lenses while refusing to acknowledge any problem at all. Now that the problem is widely known and likely cutting into sales of this lens they are finally fessing up to the problem and working on a fix. The portrait problem is real.

I can tell about my experience. The noted the problem on mine too. It gives a glossy aspect to the picture. I got in contact with photodiox and they sent me a new one straight away. The second one seems to work way better, although it still happen once in a while. Since for me its just a hobby, its not a big deal but it may be a problem if you need it to work. By the way, im very pleased with the product and i believe its the only option to use the Konica AR lenses with Canon EOS.

I didn't know it was supposed to have barrel distortion, but I'd think this would be an optical thing about the lens. I wouldn't think it would matter what camera the lens was on. Haven't noticed chromatic problems but I suppose it must be there. Hope somebody can help you more exactly.

The lens that I purchased was a new one. Having said that it arrived in perfect condition and I have taken so really incredible pictures with these lens. It has become my second fav lens. Also keep checking because Tamron frequently offers rebates , I received $75. Hope this helps.

I dont think it is caused by color wheel, it could be dirt on your projection lense. The wheel spins so fast that it will not generate any spots.

I tested both the Tamron and Sigma 70 to 200 f 2/8.`and this is my review. Every one is hot for fast AF, well the Sigma had fast AF, but the pictures it took sucked. The Tamron with its AF system took Great photos, but had slower AF. I don't know what you want, but I want great pictures. As far as sporting events go, set lens to inf., and shoot away, no problem. Thats the way it was done before all this AF. Hands down Tamron wins. I could have got the Nikon version of this lens, but even if you can afford it, what wrong with bang for the buck?

IMHO.....the issues you mention are lens and not filter issues. I use my star filters on one of Nikon's sharpest lenses, the 35mm f 1.8 DX which according to some reviewers, has a boatload of barrel distortion. Who knew? All I ever get are razor-sharp contrasty, colorful images. For all practical purposes, unless you're making huge crops, none of the above "imperfections" are even remotely noticeable, and none are caused by the filters.

I have the original version on a NEX-7. I haven't noticed any purple fringing (chromatic aberration), nor have I gone looking for it. So no comments on that aspect. That aside, to answer your direct question, both the NEX-7 and the A6000 have APS-C size sensors, and E (not FE) lens mounts, so there should be no question that either the original version or the updated version will attach physically, and will have a large enough image circle to fully cover the sensor on either camera.

You have 10mm more with the Tamron. You have twice the size aperture comparing 2.8 to 4. That is a huge huge difference. I tested mine in detail at the center and some spots around the corner AT THE SAME APERTURE with my Nikon 24-120, it is every bit as sharp under high magnification. I did quite a scientific comparison. If you know the outstanding optical quality of the Nikon 24-120, you'll be really impressed.

I am using this lens with the D3100 and have no lag issues. In less you are in very low light, or working with an image that has very a low contrast background, focus should be good. Focus with the Tamron is as fast and accurate as with my Nikon 55-300 lens, maybe faster.

I have not experienced any "purple fringing" that normally comes from light filtering glass in a prism effect. The lens have stayed clear and not fuzzy at all. there has been no "haze" like with cheaper ground glass...these are the real deal... Hope this answers your question....

I haven't heard this noise on my lens when focusing. Are your images affected in any way?

I have to return my lens. Used twice on a shoot and serious focusing issues both times. I will not pass judgment, as I plan to return to Tamron under their warranty and I bought this upon recommendation from fellow fans of this particular lens. I shoot Canon and this was the first time I purchased outside of their line...

Tamron told me there is a firmware update that must be installed to work well with the 70D. It was just developed about two months ago. Any lenses made before then will need the update installed. I just sent me lens to Tamron this week for them to update it. Up to this point I could only take a handful of pictures at a time before it brought up an error message telling me to clean the contacts on the lens or camera (can't remember the exact wording). I'm hoping all is well when I get the lens back this week.

They come out smudge. The pictures are not as clear as you hope they would come about to be. My lens just came like that, I'm not sure about the others
