I use this on my 70-200mm and my 100-400 for extra reach depending on situation. Works great! Be careful; and heed their warning. The extended part you see on this unit can break you camera sensor it you accidentally try to put it on backwards. Great tight fit and does the job as expected.
This teleconverter is perfect for that extra bit of reach on the 70-200mm GM. There really doesn't seem to be any downside to using this teleconverter like I thought there might be. The 70-200mm becomes an amazingly sharp 98-280mm f/4 lens.
Unobtrusive, easy to use. Excellent resolution on recent moon shots. Only loose a stop, but does limit to f8 at full 400mm zoom.
Pros: small, light weight, optically very sharp, even packaged beautifullyCons: expensive
I am giving this 5 stars for being small, and working as well as I might hope on my Sony 100-400mm GM lens. Focus is slightly affected, as is image quality (mostly because it is 1 stop slower, as physics would dictate...), but these affects are expected. This is as good as tele-converters get.
This has been a very good investment no loss of speed or quality and if you are thinking about it go for it you will not regret it
Using it on the 100-400GM lens on my Sony a7R2 I cannot see any image degradation. Check out the detail on the wing feathers shot at 540mm.
Took this picture of the Super Blue Moon last night with the 100-400mm lens and this 1.4x teleconverter. Nuff said.
I bought one of these with my 100-400 GM for shooting the eclipse with my a7Sii. What I found out was that I needed a a7Rii to take the fullest advantage of this lens system.
Overpriced, but very sharp. Tight fit & nice finish.
