He says it IS the II lens he's using.

Teleconverters generally work best with fixed focal length lenses, not zoom lenses.

I have the version II lens. It’s been a great lens and I’ve had it for a couple of years so since I’ve gotten into bird photography I wanted to get closer and picked up the converter. It focuses just about as quickly with the converter but the images are not sharp with it.

Canon claims it’s compatible with this lens.

All guesses without samples. Could be several things, but since you are getting good photos with out the converter, it is more than likely the converter. Or movement. Longer lens more chance for movement, but that should show as Morton, not soft focus.

Don’t think it’s motion blur as I’m using a high shutter speed and the birds are stationary. I’d hate to think how bad it would be with bif

For what it’s worth… I read somewhere once where it is important to connect the converter to the lens first and then connect everything to the camera. Don’t know if that could make a difference.

I’m currently shooting with the canon R so the converter needs to be on the lens first then the L to R adapter than all connected to the camera. I don’t think that is the problem but thanks for your input.

Will do Frank. Thanks

Until you can post some actual examples, shoot in the f/9 to f/11 range with the 1.4x installed. Check the EOS 7DII manual and see if this camera is limited to just the center AF point / cluster with the extender installed. Also, the responsiveness of the AF is 'sluggish' so work in AI Servo and have the AF engaged fully when focusing up until the point of fully depressing the shutter. The mirrorless EOS R has a different AF system, but consider similar actions if you feel you begin to achieve improvement with the 7DII.

The Canon documentation makes this recommendation. Our OP should confirm this usage practice.

I’ll check the manual when I return home in a few days. Although I do use center spot focus on the 7D ii. With the R I see no noticeable difference in acquiring focus and I always use servo mode with back button focus. Thanks for your informative input CHG_CANON. If I can’t get this to work to my satisfaction I’m contemplating getting the canon 600mm but also want to upgrade to the canon R6 or R5 if I can talk my wife into it lol.

Look at the firmware status of both cameras too. Update as needed.

I have a canon 100-400L II lens that I use on my EOS R & 7Dii. I purchased a canon 1.4 converter V-III but am finding the images are very soft. (extremely disappointed). I’ve tried upping the shutter speed etc. but still soft focus on all images. The mentioned lens used as is takes perfectly sharp images. Any way to solve this issue?
I have the same lens and teleconverter and I've used them on my 7D mk II many times. I currently have that lens combo on my 90D and have used it on my 5DSr and 5D mk IV and 6D and M50 and a few others and have not noticed any significant degradation to the images. My friend has used the combo on his T5i and T7i without issues also. I'd have the teleconverter checked by someone who knows what they're doing, like say, a Canon service tech.

Yes, I always update my firmware. I wish they would do more with the R like a few more features. I find the R lags a bit compared to a dslr. They say the R5 & 6 are noticeably faster.
