Hi all,
I've done a bit of research, but please put me straight if I'm wrong.
1. I simply cannot decide whether to get a new mirrorless system. I have a Nikon 1, and while I love the reach and the size, i would like a better system for portraits.
As I shoot Canon SLRs, the M5 seems like a good buy, it's very cheap on MPB.com and I have about another £100 to trade in, so I can get the state of the art for about £400. I shot some great portraits on the original Eos M camera, but traded it in for better AF and more reach without mounting enormous and heavy L glass on the EF-M.
Now, I have read that you can get a speedbooster to mount Canon EF fit easily for Sony \ Fuji, but there is less info about the Canon version. I have a 50mm nifty fifty and some lensbaby optics I got cheap I would like to shoot on this body, as it will be my third "special effects" body when I shoot a wedding.
Does anyone have any experience, or anything they would suggest?
2. I had an idea - which might be optically impossible - but would be interested in an experts opinion.
A speedbooster is manual focus only, because you are mounting EF to EF-M. What if the connection was EF both sides? You would then put pass through contacts on it a la an auto focus extension tube. You'd then fit the speed booster into the EF->EF-M adapter and you'd have an autofocusing speedbooster that lets you mount full frame on the EF-M cameras!
Is this optically impossible? I don't believe it already exists...
Cheers!
As far as I know, there is a seller at ebay who customizes the EF-to-EFM focal reducer with others' parts and resells it. It means that it is not a factory product, but its cost is not inexpensive, although it supports AF and IS. Some bad effects come along, of course.
Anyway, for what focal length or range do you need the converter? Now EOS Ms have 22mm/2 for 35mm equiv, 32mm/1.4 for 51mm, and 50mm/1.8 for 80mm.
M doesn't have a native 50mm .
