I'm thinking of buying this lens for the A7s, but I have read about it's manual focus issues. Someone said that it is impossible to focus manually..??

Yes you can manual focus. No manual focus switch on the lens but just select manual focus from the menu. This can be assigned to a Custom Key or the Function button (which displays a quick menu which is user configurable). The 24-70 performs well on the A7s.

Manual focus? Not impossible. That said, it is difficult to focus manual at extreme wide angle where autofocus does an admirable job.

Its manual focus works fine for me. I have the a7r and have had no problems using manual focus.

I disagree. The lens can be focused manually. It helps to activate the focusing aids. For example, peaking would help.

Yes you can manually focus this lens. There are focus and zoom rings on the lens. You just need to set the camera to manual focus mode to do it.

I have these lens and I cannot use the autofocus, only manual. It won't focus no matter at what range. So disappointed..

Are you sure? everything I have read so far states it doesn`t auto focus. Thats why I didn`t buy it yet. I can`t see buying one if I have to focus in shots anyways.

I also have this slow focus problem on my D300 and D700. Slower focusing than any other lens I have used. Anyone heard about a fix for this yet?

Hello, the lens is manual, works manually only. Please put your camera into "no lens attached" mode and continue to shoot manually on in Aperture priority mode. Thank you.

No not in auto-focus only in manual. I really prefer to focus mine in manual anyway now, just takes a little practice and you will be shooting like a pro in no time. I had one just like this and got broken but am getting another as takes great shots.

It is a full frame lens, but for it to work on the A7 (which is an E-mount body), you'll need an adapter, as this lens is an A-mount. I'm personally quite happy with this lens, but the low cost is a big reason. The much more expensive Zeiss 85mm prime lens is better, but 5-6 times more expensive.

At last! A question from a Canon owner. I'm going to say "maybe" because I'm not sure. The lens does com with an adapter ring for Canons, so I'm guessing yes. I'm just not sure about that model. I think it's that connector that makes this lens a non-auto focus. You definitely have to focus manually, regardless of what camera you can use it on.

You don't want this lens for the a7. It will attach and take photos in crop mode. But you would be much better off with a full frame lens (either native E mount, or another full frame lens with a compatible converter). If you had higher quality non-full-frame e-mount lenses, those might be worth using in crop mode, I suppose. But this lens has too many optical compromises.

Peterson:I have the same lens and want to buy a D40 - have you figured out yet if it works. From everything I read it should work on manual focus only ?

I have one. For the price... it is a great lens. Make sure it is well mounted and set camera to high contrast and max sharp. Don't run it more than 12-1500mm. Hard to focus but does a great job "for the price." On a side note: the lens mount is high maintenance and will loosen after a few uses. Make sure your camera body is supported somehow. Take the lens off when not in use.

Thus far I did not experience any issues with focusing - worked fine for me. Moreover, XS-1 has a manual focus mode with the focusing ring conveniently located on the lens housing and a switch on the body to select manual focusing mode, so if you get into a situation that auto-focus does not work for you, it is very easy to override it.

Hello Brian, in the years I have used this lens all the time and I can report to you that I have never had any problems with this excellent lens. It is sharp and the contrast and color are beautiful. Focusing has always been crystal clear. Also focus speed would be a function of the camera body which has the drive engine for autofocusing. Hope this helps, Paul

As was said by another person the autofocus is handled by the camera body AF motor. This makes it a little slower than other lenses that have the AF motor built in such as SSM lenses. That being said, it focuses plenty quick for my use and focuses accurately. I've used it with the Sony A100 and with the Sony A580.

I would suggest reading the reviews on BHPHOTO website, they are usually very objective and helpful. Sony makes a 35mm for the a7 that is not a Carl Zeiss and is cheaper.

William I am using this device on my Sony A6000 (successor to the NEX-7) and I can control all lens functions including auto focus via the camera. I have not used the A7S, but I assume it would work similarly to the A6000. Happy shooting!!!

I wonder if you are using the camera correctly. If you set the camera to continuously focus, and then try to do focus-and-recompose, you will get out-of-focus photos most of the time. The Tamron all-in-one lens, like any all-in-one lens, is not the best lens in the world. But it isn't horribly bad, either. And it normally will not do a lot of focus hunting in decent light. If you are new to SLRs, you might begin by making sure that you aren't the problem. FWIW
