With the right eBay silicone turbo adapter it fits great on a hood stacked 1979 Mercedes 300SD

I use it with my Nikon D750 and Fuji T-X10 and it does a great job.

I can hear my Turbo somewhat and i feel the difference

Say what you will about the Leica price premium but this is an amazing little monocular. I've been using it for about 6 months now and don't know how I ever lived without it. I'm a photographer and this fits nicely in my camera bag, to be used for spotting animals and people to approach and photograph. I also take it with me on extended mountain treks, where it is incredibly useful. The close-up lens is nice to have, but I find myself using it only infrequently, mostly because the case, where it is stored, is so bulky I tend to leave it home. It gets 4 stars instead of 5 due to the bulkiness of the case, which doesn't fit the lanyard, and factoring in price/value.But why the Leica? Because of the clarity and brightness of the image and the durability and build of the product. It's survived 4 foot falls onto dirt without damage. It's been inundated with rain and snow. I've let everybody and their uncle use the thing and it's still like new. The initial stiffness in the focus ring has loosened up. It's possible to shoot through the monocular using my Sony RX100M3 camera, or any smaller point-and-shoot. Just put the zoom on full and focus on infinity, then place the monocular over the lens. The results aren't spectacular, but it'll do as a long telephoto in a pinch.I look forward to decades of use of this investment, and eventually I'll pass it on to one of my kids.

upgrades the turbo noise by a lot very good product

I purchased a Canon FD to Leica M adapter in order to get some more use out of my 17mm Canon lens. I’m pretty impressed with it so far. It seems considerably better quality than the cheap imported adapters, and not as expensive as a Novoflex. The lens hooks up solid and it feels solid on the camera body. I will most likely try some of their other adapters as necessary.

The best air filter for turbo engines, better performance from what I can tell..

I like getting this fuji film instead of getting the individual ones.
