The bag suits my needs as I was able to put my two Canon EOS R6 and R7 hybrid cameras with their lenses as well as additional lenses and Godox flashes.

I bought the backpack for a Canon EOS R and a Nikon Coolpix P950. Both cameras, various lenses, spare batteries and chargers have enough space in the backpack and, if necessary, the compartments can be rearranged thanks to the Velcro.
The backpack makes a solid impression and the zippers work perfectly.

have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

It has no ports but I can still use Canon lenses on NX cameras... Can enjoy different angles.

use this for my Canon FD lenses on my Sony a5000. Fits well

Yes, you can use Canon EF lenses on Samsung NX cameras with this. But. Due to the principle, no transmission of metadata (aperture, etc.) to the camera, no possibility to change the aperture; Depending on the lens, not even the focus can be adjusted (which actually makes these lenses unusable) So: This adapter is a good one, but such adapters should be avoided if possible.

Yes... it works perfectly with Canon EOS M cameras. I own Canon EOS M10 and use this adapter most of the time with Canon 50mm 1.8 lens. It is amazing. The autofocus is accurate and fast enough. If you own a Canon EOS M camera, I recommend you this adapter because it is much cheaper than Canon original and there is actually no difference between them. Everything works as it should. I love this adaptor. The best purchase I've made for my camera.

ordered the adapter to use a vintage Tamron mirror lens (5.6/350 mm) on my two Canon bodies EOS 5D mkIV and EOS 1Ds. Since both cameras are not listed in the compatibility list of the item description and one often hears (with other adapters) that the camera mirror can no longer move freely and therefore error messages or damage to the camera occur, I was curious whether that would also be the case my two cameras would work. It works out. The adapter is also seated without play, attaching and detaching is easy. It was clear to me beforehand that the focus and the time setting had to be made manually. Unfortunately, the invoice must first be requested from the seller, but it came within 24 hours as a PDF by email. However, it is an import invoice without deductible VAT and in the "worst case" the tax office will still have import sales tax when it is submitted. At the price of the adapter, however, that can probably be gotten over.
