Canon 7D mk2 and a Tamron 150-600 5.6 /6.3

When I used this Tammy with a Canon 60 D the images seemed quite sharp but now I'm using the Canon 7Dmk2 when using auto focus in servo mode, on /off a tripod with image stabilizer on/off most of the images are not sharp, when blown up. Even though they look sharp in the camera's LCD monitor. I have tried different cases in the camera autofocus settings, all to no avail and different F stops F6.3 F8 F9 and different ISO settings and therefore different shutter speeds. On stationery subjects the images are fine, but not birds in flight or other fast moving subjects. All other lenses produce sharp images including the Tamron 70- 200 2.8. The lens has had the latest firmware installed. When questioned at the Birmingham (UK)Photography show Tamron insist even when blown up to 1 to 1 the images should be sharp. As this lens according to them , does produce sharp images, with the 7DMk2. Canon of course non committal, "we do not make that lens, our 100-400 would be our recommendation" the lens has been back to Tamron once. Its spring I'm getting anxious as the birds are doing spring things and I'm not getting the images. HELP. Any bright ideas ? Thank you in anticipation.

Did you calibrate the AF for the lens? Try MF and see if it is sharp. If you have any vision problem at all then use live view, magnified. That will tell you if your copy of the lens and your body work well together. Does the body have the latest firmware?

I'm not familiar with the 7D mk2, but does it have the ability to adjust the focus point on the camera to match up with the Tamron lens. The focus point for the Tammy may be a little off for the 7D. Also make sure you shutter speeds are high enough to freeze the action on moving subjects. At least 1/600 of a second or higher, probably twice that. I have the 200 to 500 Tamron I find the same problem. On the one it focuses fine and on the other I'm having issues.

I have the same camera/lens combo. Once I microadjusted my lenses to the camera, I get lots of razor sharp photos

Yes, you need to micro adjust the lens. Look in your manual to see how or call Canon.
You don't need anything fancy, just something with fine or sharp contrasty lines that shows up well. If the focus is more than 10 clicks off in either direction, Canon recommends you send them the lens and camera but I doubt they will touch that Tammy! So you can only send the body.
Don't know what the camera will allow you to do with a 3rd party lens either. Good luck. ;-)

I seem to remember when the 7DII first came out there were problems with some of them and the Tamron 150-600. Didn't someone post that they sent the camera and lens to Tamron's service center for tweaking?

I tried the micro adjustment myself, but I'm not sure I got it right, so the combo is going on Wednesday to my local dealer,. Thanks for your reply

I thought I read some where that is what happened. I suggested this to Tamron but I think they are hesitant about touching the Canon Body. I can only hope the micro adjustment will work.

Yes there were several bodies that didn't play well with the Tamron when it was first introduced. I maybe wrong but I do remember the 7DII and the 5DIII were a couple of them.

Maybe a firmware and a dock might fix this.

There are always higher risks of non compliance with 3rd party lenses unfortunately.

I know Tamron had a firmware fix for it. I sent mine in for it. One of the things in Canon's firmware update for the 7DII had to do with AF problems also.

I agree about the 3rd party lens but Canon don't make a 600 mm lens for under a £1000 and I studied what people said about the big Tammy for over a year before I bought mine, thinking any of its problems were sorted. Thanks for all comments.

One of the members in Australia (I think) had problems with his Tamron, sent it in three times if I remember right. Tamron sent him a different copy of the lens, no more problems.

No matter how good the company or product every so often you get a lemon.

Can you fine tune the lens to your camera? Will the 7DII allow you to fine tune a lens? That lens may be fine on one camera but not another. Fine tune it to that specific camera. Should help.

I have used the Tamron on both my 6d and my 7DII.
The only word I can use to describe the results is ....inconsistent.

I've gotten some tack sharp images and I've gotten many gigabytes of trash and I've been unable to pin down exactly why.

My lens has been off to Tamron 3 times and it has the very latest firmware, I've micro adjusted it until I'm sick of doing it, I've tried VC on and off, Tripod, monopod and anything else I can think of.

I met another photographer at a famous bird photo location in January. He had just sold his Tamron due to inconsistent results (he used the same word).

The symptoms are weird (at least to me).
If the subject is within say 40 feet and the lighting is very good I can get some very good images if I use a high enough shutter speed (1/1250 or higher) and f8. This means, of course, using a higher than ideal ISO....but the images are good and that's the price of a 6.3 lens.
When the subject is far off, say 100 ft or more, the odds of getting anything that isn't pretty soft are almost nil. Even on a very solid tripod and even if I don't end up having to crop very much.
However.....this isn't true 100% of the time. As I say, it's inconsistent.

Very frustrating.

One thing that I have noticed that might help.
I use back button focus so I don't depress the shutter until the instant that I want to shoot the picture. This means the VC is still trying to stabilize when the shutter fires. A sure formula for a bad image.
I've tried to train myself to press the shutter half way for a second before I take the shot but I'm not always successful and I am so used to BBF and it's advantages that I don't want to go back.

If I was 100% sure that I myself weren't the problem I'd get rid of the lens and fork out the extra money for the canon 100-400 II. I wish I knew someone local that was completely happy with his Tamron so he could give mine a try.

When I use my 70-300L, handheld and wide open I can get great images even with fairly dramatic crops so..............

Are you having the issue with both the 6D and 7DII or just the 7DII?
