Tamron SP 24-70 f/2.8 Di VC USD Lens and Canon 6D Mark II

sustain — Fri, 19 Jul 2019 18:52:11 GMT

I recently purchased a new Canon 6D Mark II and was hoping that the Tamron lens would work on it. It fits ok but I only see a small square of light coming through the lens, no images. Are there any compatibilty issues here? Anything I can do to fix the problem. Thanks.

I would say it is likely one of two possibilities. Either you have a bad lens, or there is shipping and packing material in the lens mount.

I would have thought tat but the lens works fine with my Canon 70D.

The lens may need a firmware update. Contact Tamron.

Sustain,

I own the same body. Looked at the Tamron (G2 version), but in the end, went with the Sigma.

Tamron has had multiple compatibility issues with Canon. Some of their lens are troublefree others quirks that appear to have been corrected with FW updates (mostly). You'll need a TAP-In adapter to update FW.

The v1 lens is no longer for sale.

If you have the non G2 model (A0007) revision, there is no FW

If you have the G2 (A0032) variant, updated FW exists

Tamron lens compatibility

https://www.tamron.com/faq/products/checker.html

Site lists the v1 and G2 variants as compatible with the 6D2

While I believe Tamron makes good products, I'm happy I went with Sigma in the end. I compared the 2 for weeks. The factors that influenced my decision:

I have both the Sigma and Tamron 24-70 f2.8 lenses and both work as advertised on my 1D Mk IV and 1DX. I have never been a fan on the 6 series so I can't say about it. Any third party gear can have problems so it is always better to stick with Canon gear.

BTW, if you are curious the Tamron is by far the better lens than the Siggy. I would contact Tamron whose CS is far better than it used to be. If you are considering a 70-200mil, the Tamron SP 70-200mm f/2.8 Di VC USD G2 Lens is the better choice too.

However, Canon's offerings in these focal length ranges is head and shoulders above any of the others.

I would agree. I don’t have the Tamron, but I have the Sigma and the Canon and the difference in focus speed makes the Canon worth the money. The canon is also much sharper and has better contrast.

The Canon EF 24-70mm f/2.8L II USM is extremely sharp, even at 24mm. Definitely worth the money!

The above image was shot with a 6D Mark II and the EF 24-70mm f/2.8L II USM lens.

"The Canon EF 24-70mm f/2.8L II USM is extremely sharp..."

Absolutely but curiosity is why I buy and try and use others. My retirement hobby if you will. I know what they can and can't do so I don't have to rely on the liars on the ole inner web. Canon is almost always the winner and not just by a bit but substantially better.

BTW, b&w is not a great example to prove sharpness. Contrasty edges tend to make a poor photo look sharp even when it isn't.

I am surprised to hear you say that. What you say was true in the film era. In the age of digital images, color requires more bits per pixel.. Given equivalent file size limits, a digital black and white image icon typically havea a much higher resolution than a color image.

Instead of devoting 24 bits per pixel for a color image, a B&W image can get away with only 8 or 10 bits per pixel. This means I can fit for more black and white pixels than color pixels into a fixed file size limit. I limited the black and white image to 6 bits per pixel, so the full resolution image fit under the file size limits.
