Using it on a Contax 645. Very comfortable. Great price.

Works perfectly for my Contax 645 and is easy to slide on the little nubbins on the body. Quite comfortable too.

I love this mount. It is not compatible with the Nikon FTZ adapter unless you move it from the body to the adapter or buy another mount just for the adapter. I’ve hike a couple mountains and bustled through crowds without fail using this mount.

Part 1 - Minolta MD to Sony NEX adapterTechnically, it slightly overshoots infinity but the issue is easily corrected by dialing back the focus ring just a tad --- Not exact but clearly better than not-at-all.Although very light due to extensive aluminum usage, the build quality and fit-and-finish of the adapter is superb. Connections on the lens and camera mount sides are tight and precise --- absolutely, zero slop. The top of the lens release button is flattened making the lens removal process very easy and comfortable.Other notes:- There are no electrical connections so focus and zoom must be done manually on the lens itself- When mounting the lens, turn the adapter clockwise till you hear a "click"- Tested with a Minolta 85mm f/1.7 Rokkor-X MD lens mounted to a Sony a6000 camera-----------------------Part 2 - Nikon Ai to Sony NEX adapterEdit: Based on my positive experience with the Minolta MD adapter, I also purchased the Nikon Ai adapter later.As with the Minolta MD adapter, the Nikon Ai version focuses beyond infinity a tiny bit. Fortunately, the same solution applies - dial back the focus ring and the horizon will become crystal clear. The build quality is impeccable and the finish is smooth and clean of burrs or machine marks. Connections on both sides are taut and precise with zero play.Additional notes for Nikon Ai adapter:- No electrical connections present so focus and zoom must be done manually on the lens.- Unlike the Minolta MD adapter, mounting the lens for Nikon adapter requires a counter-clockwise turn until you hear the "click" of the locking mechanism- Tested with a Nikon Micro Nikkor 55m f/2.8 Ai-S MF lens mounted to a Sony a6000 camera

Having acquired a Contax 645 Medium format camera I realised I needed a strong durable camera strap that would fit the Contax camera lugs securely without the anxiety of any issues supporting such a unique camera.Having read many reviews and forums in reality Op/Tech Super Pro B Strap met all my expectations. The strap can be purchased with the A or B Strap and as described by many photographers the B strap connectors were a perfect fir for the Contax 645 with lockable sliding mechanism at each connector that reinforces the attachments giving you more peace of mind where your camera support is concerned.The strap support is made well, wide and sufficiently padded to demand the name of Super "Pro" and initially feels comfortable although I have yet take a lengthy walkabout with it. So I will report back about my experience. The great feature is that you can detach the connector straps from the shoulder pad and connect the appropriate Op/Tech connectors for any other camera whilst taking advantage of a quality support system.I would recommend this strap to any semi pro/pro photographer who wishes to support their Contax 645 kit or any other camera the B straps fit using a well constructed product from an established manufacturer.Before you purchase make sure you check if your camera connectors support the A or B Strap connectors

Got this for my Contax 645 since the straps (and essentially every other Contax accessory) costs an arm and a leg nowadays. OP/TECH USA Super Pro Strap (design B) definitely fits the Contax 645! The foam-like neck portion of this strap is super comfortable and really helps relieve some of the weight from heavy medium format cameras. Very glad I made this purchase!

Isn't the Carl Zeiss optics lens as advertised but it;s a much clearer picture now so... I got that going for me, which is nice.
