Switching camera systems can be a big deal if you already own a lot of glass. This is especially true if you own several professional lenses. Lens adapters like the Canon to Sony Metabones V can help, but may not be right for you.
I recently went through this painful process. I had spent a considerable amount of money buying a full frame 6d mark ii body, and three professional canon lenses.
However, when shooting video, the 6d mark ii was limited to 60fps. This is fine for a lot of things, but I really wanted 120fps and not just from my GoPro.
To get 120fps from a Canon, means jumping up to the Canon 1dx mark ii, which sucks. Not because it is a bad camera. Everything I have read and seen suggest it is a wonderful camera, albeit big and heavy and significantly more expensive.
The steep price of the camera body and required memory cards was discouraging so I looked into other options.
After a lot of research and thought, I decided that it made more economical sense make the switch to the Sony A7iii. The body was much more affordable, it came in a smaller form factor and can shoot 120fps.
Switching camera bodies was the easy part. Switching glass was more difficult.
If possible, I wanted to use an adapter so that I could use my Canon lenses on a Sony camera body to see if I could keep my current Canon glass. I purchased the Metabones 5 adapter, making sure to update the firmware.
It adds a little bit of extra weight and slightly alters the balance of the camera, but the pictures were amazing.
I was pleasantly surprised by how responsive it is and the autofocus is more than adequate. I had worried about the autofocus being too slow.
The photos looked nice, so I thought this is it. I had just saved myself a ton of money.
Unfortunately, my excitement took a dive. The wonderful performance of shooting photos disappears when using the Metabones adapter to shoot videos. The autofocus is not impressive at all and while I like to shoot some things with manual focus, I also like autofocus for a lot of my shots.
A quick search, revealed that this is a common problem that also affects adapters from other manufacturers.
Because video is high on my priorities list, I made the decision to sell my 16-35mm and 85mm lenses and switched to native sony glass versions of those lenses. I did keep the Canon macro lens and the Metabones adapter to pair with this lens as I typically focus manually with this lens.
So, should you get a Canon to Sony Metabones V adapter when switching to Sony?
Yes. If you primarily shoot photos, I think the Metabones 5 adapter is an amazing way to save money.
No. If you want or need solid autofocus when shooting videos, then you will be better off with native glass.
While it was painful selling the Canon glass, I would do it again. I am very pleased with the Sony a7iii and the native lenses. I also like the Metabones / Canon 100mm macro lens combo. It will probably be awhile before I pick up the native sony macro lens.
Have you used a lens adapter on your Sony camera? What was your experience?
