I performed focus tests with all of my EF mount lenses with my R5 mirrorless using a focusing chart on a 45-degree angle. The focus for every Canon lens was spot-on, including the 100-400mm II with 1.4x III that I had to micro-adjust significantly for my old 7D II. No surprises with the Canon lenses.

However, in testing the Tamron 150-600mm G2 lens, the focus was way off. Focus was 1-2 inches nearer than the intended focus point. Completely unusable on the R5 as-is. The lens when mounted on my 90D crop sensor is pretty good at the focus point, but I can see it stays in focus all the way down the chart 1-2” closer to the camera, therefore it also has some front focusing issues, just not as bad.

For those of you who have the Tap-in console and have used it, does it do a good job in correcting this front focusing problem? I don’t have the Tap-in console, and am wondering if it is worth the $59 to purchase at this point.

I’m a little on the fence whether to stay with the Tamron or not. The wide focal range in one lens is great for wildlife. Note that I do have the RF 800mm f/11 on order which will extend my focal range even on the R5 with full frame sensor, but in a fixed focal length. My intent was to use the crop sensor DSLR with the long telephoto zooms for wildlife for a while, and the R5 with shorter lenses for everything else. With the R5’s animal eye focus, that may change my strategy. I just don’t know how well a focus tuned Tamron would work with it.

And, then there’s the rumored R7 mirrorless crop sensor body that may be released soon!

I have a friend who just bought an R5 and I’m pretty sure he has that same Tamron lens. I’ll have to remember to ask him if he has similar issue and if he had the Tap in console you mentioned.

Thanks Basil. I appreciate it. It would be nice to hear from someone with the console and how effective it is.

Interesting that the focus was that far off with the R5. Doesn’t that focus on the sensor? Are you sure your focus point was accurate?

The tap in console will work fine to fix this. However, it is a rather tedious process to do, especially if you set it for several focal lengths. In the end, it is worth the time to do if you decide that the flexibility of the zoom is what you desire.

I believe Tamron recommends you send it in to get reset or nothing.

I have a friend who has an R6 and uses the Tamron 150-600mm G2 and is having the same problem you describe with the focus. She also has the tap in console and it has not corrected the problem. Perhaps Tamron has an answer as you don't seem to be the only one with that combo who is having a problem.

Bought the f11 600mm prime and it takes great pictures. High iso. Lens. Difficult for BIFs. I use it on my RP

It may need a firmware update.

Contact Tamron and they will confirm that it need a update.

Just FYI, my friend just informed me that he has had no issues with focus with his R5/ Tamron G2 combo. He does have the console but has not used it to adjust focus.

They did update the firmware

Thanks everyone for the comments and info. I did a quick search and found the following. It does look like there is a firmware update that addresses this issue.

Notice of Firmware Update for Tamron Lens compatibility with Canon EOS R and Mount Adapter EF-EOS R

December 20, 2018, Saitama, Japan – Tamron Co., Ltd. announces a new firmware update for the Tamron SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) for compatibility with the Canon EOS R and Mount Adapter EF-EOS R. The new F/W version makes the model compatible with Canon "EOS R" and Canon "Mount Adapter EF-EOS R" for general operations [1].

The lens firmware can be updated with the separately sold TAP-in Console.

I had the first model of the Tamron (1st month they were out.) used with a 7DII & 6D. The 7DII and the Tamron did not play well together either. But my 6D and the Tamron worked so well it was as if Tamron used a 6D to design the lens.
As per a phone call I sent the lens to Tamron and they did the firmware updates(2) and adjusted the lens to work with a 7DII. The same day I got the lens back Canon also released a firmware update for the 7DII that addressed the problem.
My G2 has never had problems with any of my family's bodies (6 different Canons-5 aps-c and 1 FF). Though the 90D with 32MP packed into an aps-c sensor is EXTREMELY sensitive to motion blur, esp. out at 600mm.

I found the same thing with my Tamron lenses but was able to correct with the Tapcon
