I am in the process of selling my Canon 80d with kit lens. I do plan to keep my Canon EFS 17-55mm f2.8 IS Lens. I would like to purchase the Canon M50 mirrorless. I need a smaller size and weight camera for hiking in desert and easy stills photography. Which adapter should I purchase to receive the most from my Canon EFS 17-55mm f2.8 lens? In addition, I plan to purchase the Canon Macro 100mm f2.8 lens for closeup images of my rock and mineral collection. Which lens adapter would be best for both of these lens on the Canon M50 ???? Thanks for any helpful information.

That depends on why you are getting the adapter, and what you mean by "most"

The Canon Adapter allows you to use a lens on the M50 exactly as you would on any other "APS-C" camera.

B&H has "Speedboost" Adapters by Viltrox and Metabones which are claimed to give you the same view from a M50 that you would get from a "FF" camera with a 1-step increase in exposure. These have glass optics in them of course, so I don't know what the effect on image quality is.

Thanks rehess, yes I have studied the Canon and Viltrox, is there a third or fourth adapter that works real real good with the 2 lens and M50 ........ that's what i'm looking for too ....

I do not have an M50, so I have only reputation to go by. If you look at the B&H website, they have a whole bunch of adapters, but honestly I personally put most trust in the Canon adapter, because all the mounts here are proprietary and their’s is not that expensive. Metabones has a good reputation, but their “Speedbooster” is so expensive I have a hard time mentioning it when it is your money {rather than mine} at stake.

The "Speedboost" adapters have optics that may or may not work well with the lenses you choose to adapt.

The Canon EF/EF-S to EF-M adapter has not optics to hinder image quality, but passes through all the electronics so that lens' AF, IS and aperture control all work as usual.

The Canon EF/EF-S to EF-M adapter is fairly expensive at $159.

There are far less expensive third party adapters that do essentially the same thing, adapting EF and EF-S lenses for use on the M-series cameras. These are not Speedboost... they are "plain" adapters from Vello, Fotodiox and Viltrox (there are probably some other brands, too).

Do they pass through electricity or do they pass through meaning?

I.e., are EF signals the same as EF-M signals, or do they require modification going from one to the other?

I would be more comfortable with third-party adapters if you can assure that the signals don’t require modification going from one mount to the other.

All those would work with your EF-S 17-55mm. There is probably some difference in build quality between the Canon and the third party adapters (usually is), but I can't say from personal experience.

Regarding macro lenses... You mention using it to photograph mineral and rock collection. The Canon 100mm macro lenses are excellent (there are two). However, these may not be the best choice for tabletop studio work, if that's what you intend. I use a shorter lens for close-up work when I'm dong that sort of shooting. The reason is that this requires less working space. I can reach out and arrange the subject on the tabletop while looking through the camera's viewfinder. The 100mm puts you a lot farther from the subject, requiring more working space and putting the subject out of reach unless you are using it at or very close to max magnification.

I use a Canon TS-E 45mm when I'm doing close-ups of small items on a tabletop with an APS-C camera like yours. That's not a macro lens, though it can be made closer focusing with extension tubes. However, my subjects are usually 1:2 or 1:3 (half life size or one third life size) at most. The TS-E or "Tilt Shift" lenses are manual focus only, but the movements can be helpful for some types of close-up work.

The Canon EF-M 28mm Macro for use on the M-series cameras might be too short focal length. At high magnification there would be almost no working distance between the front of the lens and the subject. On the other hand, a neat feature is that it has a built-in LED ring light.

Canon EF-S 35mm Macro would give a bit more working space... maybe enough, without it being too much. It also has a built in LED ring light.

For a little more working distance, Canon EF-S 60mm Macro also might be good choice... Tamron also makes a nice 60mm macro, unusual with an f/2 aperture (a stop faster than most). Yongnuo has recently introduced a 60mm f/2 Macro, manual focus only.

There also are some 50mm macro... Canon made a "Compact Macro" EF 50mm f/2.5 in the past (1:2, adapter or extension can be used to increase to 1:1). That lens is no longer being made, but is still widely available used and is quite affordable. Rather than the matched 1:1 adapter that was available for it, I'd just use standard macro extension tubes if higher than 1:2 magnification was needed. (I use the Kenko tube set, as well as several Canon tubes. Mine are all EF, so would need an adapter to use on M-series. There are macro extensions especially for M-series, though I think they have fewer sizes.)

Sigma also made a 50mm Macro in the past, might find it used.

The Canon TS-E 50mm f/2.8L Macro (1:2) and Zeiss 50mm Macro (1:1) are superb... but very expensive and both are manual focus only.

All the above 35mm, 60mm and 50mm macro lenses would require an EF/EF-S to EF-M adapter.

Venus Laowa makes a 65mm Macro that goes as high as 2:1 (twice life size) and is available in EF-M mount, no adapter needed. I am pretty certain it's manual focus only.

There's also a 7artisan 60mm Macro (1:1, manual focus) made to fit EF-M and quite affordable.

If you search for macro lenses for Canon you'll find some of the new RF lenses... Those *cannot* be fitted to or adapted for use on an EF-M camera.

Hi, I have an M50 and I use the Fotodiox Pro EF-EOS (M) Auto adapter. No glass inside, just like the Canon. VERY tight on camera and lenses. ALL of my Canon glass, including L lenses, the 17-55 2.8 EF-S IS and Sigma 150-600 C work FLAWLESSLY and VERY FAST FOCUSING!
Hope this helps.

Hi, I just sold my Canon M50 and had a Canon brand EF to Eos-m adaptor that worked great with all my Canon lenses. I just sold it on Ebay for $78.00. I also have a Vello adaptor which also worked great. The big difference is that the Canon adaptor had a tighter fit than the Vello but they both worked the same. I loved my little M50 and the only reason I sold it was that I got a Canon R and just didn't need both. By the way I am getting ready to relist the Vello adapor back on Ebay for $29.00. You will like the Canon M50.

I use a Vello adapter with mine and it works great.

I have the canon m5 and have the canon adapter and the vitronox adapter the canon works much betterfor mall conditions.

I bought an M50 and it came with a Canon mount adapter EF-EOS M. I had occasion to speak with a Canon rep. During our conversation, I mentioned that I read that adapters make you lose picture quality. He said if you use a non-Canon adapter or another brand lens, that might happen. However, if you stay in the Canon line that doesn’t happen. I can only say, that in my experience, I haven’t seen any loss of quality using a Canon adapter with my Canon lenses.

Hello Roger if I were you I’d go with Canon the reason I can say it works perfectly plus backs their product’s 100%. Keep it a system ORM is the best bet in my opinion.

I have and use both Canon and a Fotodiox Pro adapter; the only difference is that the Canon salesman doesn't draw a salary for the latter's sale. Save your money and your back when backpacking. Buy the M5 or M50 with 11-22 compact WA, 28mm Macro, and whatever compact M series lens that covers the longer range you think you need. I have the Tamron 18-200 but don't recommend it for backpacking because of the weight. The 28mm Macro, a 44mm full frame equivalent, is remarkably good, and might even do what you are considering a full frame macro lens— oh so pricey and really only appropriate for a full frame camera— for your macro projects. The M series cameras take good pics but can not focus in poor light as successfully as the optical viewfinder Canons, with their M lenses, and especially not with EF/EFS lenses plus adapters. Still portable cameras tho! Both my Olympus and Fuji cameras do all of these chores better, but having a Coleman chest full of Canon lenses I still keep messing around with Canon— and there is a bit of brand loyalty mixed in as well.
