Used on an A6000 is there a crop factor? Is it 16mm at that focal length and 70mm at the other?

Yes, the factor is 1.5, so the 16-70 lens is really 24-105 35mm equivalent.

Hi, this Sony A6000 has a sensor size of 23.5 X 15.6mm. This Sony lens, SEL1670Z is an APS-C type of lens for which cropping factor is about 1.5-1.6. -Ely

17-40 should do very well. It's wide enough, though you need to decide if 40 mm is enough for you on the long end. If you don't need that wide a lens, the 24-105 is a good alternative though on crop sensor 7D, the wide end is equivalent to almost 38mm. Just consider all these factors before final decision.

It will be almost identical - the 60D is a 1.6 crop, so 10mm is effectively 16. I would (and have) just shoot with the 60D + 10-22.

It only manually focused on my d600. Not sure if I bought a bad copy or what. I returned it and purchased the 16-35mm. Good Luck!

Thank you for the excellent reply PD. What do you guys think about using the 70-200 lens with a camera that does not have a full sized sensor? I have a rebel XT and I think thats almost half the size of the 1d sensor. Still a good focal length?

I'm going to say it's a little overkill, but the lens is a great value. You'll get the cropping factor, but I think that's actually beneficial in this zoom range... with my a99, I often long for more zoom! I've also used it on my a77, and it does great. If you have more questions, do shoot 'em back!

the answer is yes to both questions. It's a matter of what you were trying to shoot. It's a good lens for the 70 to 200 millimeter focal length.

I believe the 70d is a crop-sensor, so it would give you the full-frame equivalent of 56mm.

I use this lens on the new d600 which has a full frame sensor as does the older d700 , so I assume it should be just fine

one more question. If I get the 15-85 efs lense do I still have to multiple the 1.6X crop factor to get the true range for the lense , just like I would have to do for ef lens on a rebel t1i?

Not really. The is is the only thing different and that is nominal at these focal lengths. I use it for High vibration environment when shooting video.

I do not have a full frame - A200, A700, A65. DPReview and the Dyxum, forums are your best friend on this one. So far the lens works fine initial pictures are good.

IS will not matter at this focal distance. Only start worrying about IS (or VR as Nikon refers to the technology) past about 70mm

I get that same problem (I also have a D7000). However, on mine that is only for close-up macro-type images (when I snap the photo, the focus seems to be farther than where I focused - I lost out on some neat bug photos because of it, and did a lot of testing compared to other lenses). It does OK at distance. My adjustment is less than that (I don't remember it), but I don't use it much for close-ups. I use it mostly for wide shots and landscape work, and also inside museums. In a perfect world, I would buy the 24-70mm f/2.8 Nikon, but this is a third of the price, and for my application is fine. However, if you are shooting people at closer ranges, I can see where it might be an issue. That far off, and it might be worth talking to Sigma about it. They might be able to either fix it or replace it.

Hi, thanks question. This lens can not work autofocus for D7000. Thanks in advance.

On the NEX 6 this lens has a focal length equivalent to 105-300mm on a full frame camera such as the a7r. I don't have a NEX 6, but it works beautifully on an a6000.

Totally depends on what want to do with it. All I can say is 18-35 mm on a crop frame gives u wide angle and portrait and all that at a constant f stop of 1.8....Its a super awesome lens
