Excellent product

Reviewed in the United States on November 2, 2023

This is an excellent product, worth the slightly higher price compared to bargain adapters. It is solid and secure, rotating into place with a satisfying click. I can't comment on that auto focus aspect, because I use this adapter only with manual lenses. But in all respects that I'm familiar with, this adapter functions very well.

High quality but not electronic. Make sure your lens has the RED dot, not white.

Reviewed in the United States on June 10, 2018

Don't be confused by what this adapter does and doesn't do. Many reviews and answered questions are misleading. Just to be absolutely clear, this adapter works with the Panasonic Lumix G7 body and Canon EF lenses, NOT Canon EF-s lenses. If your lenses have the RED dot, them this adapter will work for you. If they have the WHITE dot, then you will not be able to focus the lens when mounted and should not bother with it.

K&F has a good product here. The ir build quality is very good and the adapter fits very snug on the camera and Canon lenses. K&F's description of the product is also accurate... it's for EF lenses. Just be advised that this is a mechanical adapter... it has NO electronics and your Lumix G7 will not be able to auto-focus an EF lens nor will it be able to adjust the aperture. Once an EF lens is mounted, you are on your own in the camera's manual mode only.

Once you mount a lens on the G7, you will need to go into C mode (custom) on the settings dial and toggle down to turn ON the setting that allows the camera to operate without a lens. That will allow the shutter to operate. Unfortunately, the adapter does not come with instructions so this isn't obvious.

Sadly, my EF-S lenses are the smaller ones that I wanted to use with the G7 and that is why I bought the adapter. Shame on me for not realizing that they are not what it was made for. Don't make the same mistake.

Got some funky lenses recently through various camera acquisitions and I thought it'd be fun to try them on my Olympus EM1 Mk2, particularly the 400mm that steps up to 80mm on MFT cameras. The adapter works flawlessly! It;'s solidly built and I've had no issues or wobbling. I would not hesitate if you need to adapt some old glass to mft cameras!

Lenses fit a touch stiff but it hasn't been an issue yet.

I'm using this to adapt my Minolta SR mount (MC and MD) lenses to my Lumix GX85. The adapter fits onto the Lumix MFT mount great with a smooth twist and just enough resistance. Some of the SR mount lenses fit a touch stiff though and I worry about breaking the aperture ring when trying to remove these lenses from the adapter, as it is sometimes hard to find a good place to grip the lens. Fortunately, these vintage lenses are built tough, and it hasn't caused issues yet. Whenever swapping lenses I remove the adapter (with lens still attached) from the camera body first. Then I swap the adapter to another lens before I put the lens and adapter back on the camera. That way the stiffness of the SR mount doesn't stress the MFT mount. None of my lenses have any looseness or play when attached with this adapter.

Works well, but be prepared to the restrictions

Reviewed in the United States on August 27, 2017

Size: EOS (EF/EF-S)-M4/3Verified Purchase

I bought this to use some of my Canon and 3rd party EF lenses on an Olympus E-M1 Mark II camera. As I have most general lenses for the E-M1 I really only needed it for 2 of the EF lenses, one a Tamron 150-600 and the other a Canon 100mm Macro. Both worked properly with this adapter and I was able to get good sharp and very usable photos with it. However there are some restrictions with this adapter that should be mentioned.

One, this is a "dumb" adapter in that it has no electronic components and thus there is no communications between the lens and the camera. That means that auto-focus, aperture adjustment and lens stabilization will NOT work. If you need those you need to look for some of the more expensive converters that contain electrical connections.

Two, your camera will not know a lens is attached so you need to make sure you can shoot "without a lens".

Third, since your lens becomes a strictly manual lens you can not adjust the aperture from the camera and you will either end up shooting wide open or you will have to set the aperture of your lens with the native camera for the lens and then find a way to dismount the lens without resetting the aperture. I do this with the DOF button on my Canon.

Lastly, you have to be prepared to focus manually. If your camera provides "focus peaking" you might want to use that to get your shots in proper focus.

If you are prepared to use your camera with the above restrictions this is a great little adapter and I have been able to use my EF lenses to good advantage and been very please with the results. The adapter seems solid and well made, but comes without any case or end caps to keep it clean and undamaged. Mine came in a plastic bag and I now store it, in my camera bag, in that plastic bag or leave it attached to one of my EF lenses in the lens case. Since this adapter fits an EF lens on one side and a M4/3 camera on the other you probably can also buy an Olympus lens end cap and the Canon camera body cap. That is what I plan to do to keep this clean.

K&F Concept M42 Screw Mount Lens to Micro 4/3 - Excellent buy!!!

Reviewed in the United States on March 18, 2015

Size: M42-M4/3Verified Purchase

Excellent product! Shipping was a long wait, but it was worth it! Great craftsmanship, looks exactly as pictured in every detail, more than I can say about other adapters I ordered that only looked great on pictures.

Pros:
- Very good smooth paint finish
- All metal construction
- Durable (been using it over a year now)
- The lens screwed in the correct way (not upside down)
- Snug fit to my Lumix GH2, no jiggle.

I cannot find any Cons...this is just a beautifully made M42 to micro four 3rd lens adapter. Even the product packaging looks good. Highly recommended for those looking for M42 Screw Mount Lens to Micro 4/3 adapter. Now I can finally use my Yashica Yashinon-DS 50mm f/1.9 on my GH2. (I'll add photos when I can)

-Update: Over a year later & the adapter is still in very good shape! (04.24.2016)

Does the job

Reviewed in the United States on March 17, 2018

Size: EOS (EF/EF-S)-M4/3Verified Purchase

Quality build. Works great with most of my Canon lenses, except the nifty fifty, which only works in a quasi-lens whacking mode. Something about the alignment on the lens doesn't permit the focus ring to have an effect when attached to my G7. I've seen other reviews that say it works with their 50mm, others say it doesn't; I'm one of the unlucky ones. Still, well worth the price - it's quick to attach, solid, and feels like it will last a long time.

EDIT 3/31/18: After toying around a bit, I've found a way to get this to work with my Canon 50mm. It involves attaching the lens to my T3i, obtaining focus, and then reattaching the lens to my G7. Sometimes the focus ring works, sometimes not, but after attaching the 50mm it will be in focus, though only at the exact focal distance (100mm for me due to 2x crop factor). I like this product enough that I ordered a few older Canon EF lenses, so I'm still a happy customer.

Very impressive

Reviewed in the United States on March 15, 2017

Size: EOS (EF/EF-S)-M4/3Verified Purchase

I got this adapter to use some semi-functional EF-mount lenses with my OM-D E-M5. I wasn't expecting this good an adapter for the price. Feels very solid, infinity is preserved and focus scales seem to still be accurate. Of course you don't get autofocus, but manual focus works perfectly well in most scenarios. In addition, there's no way to change the aperture with this adapter directly. Instead, you either have to use lenses wide open (which makes manual focusing a bit difficult) or attach a lens to an EOS camera, hold down your DoF preview button, and then take it off and put it on the adapter. This is a bit of a tricky process and certainly not suited to fast-paced professional shoots, but for landscapes or studio photography where nothing's moving very fast it's a great, inexpensive way to use nice lenses with alternate systems.

Good dumb adapter

Reviewed in the United States on July 14, 2023

Size: EOS (EF/EF-S)-M4/3Verified Purchase

This adapter is dumb, meaning it does not enable the electronics inside the Canon lens. I use this adapter to attach my old Canon lens to my Olympus camera. It works well in that regard and is a very solid piece of camera equipment. With the price being what it is, it's worth it if all you want to do is attach a lens. However, it lacks the ability to auto focus, which causes a problem especially with my prime lens. So this adapter, being a good price and designated functionality, is not actually that useful in my opinion. A smart adapter is about $200 more though so decide if this is what you want.
