Introducing the Slim M Eyecup for the M camera System a sleek, minimalist eyecup crafted for glasses wearers and those who prefer a streamlined design.
The Owlkrown Slim M-EyeKup was designed specifically for digital Leica M bodies that use the M14 × 0.5mm OR M12 x 0.5mm rangefinder eyepiece thread. The goal was simple, cut peripheral light without killing frame line visibility, and stay comfortable whether you shoot with glasses or not.
The installation is very simple. Thread the eyecup directly into your digital Leica M rangefinder eyepiece. Do not over-torque. Gently screw it in until a snug, secure fit is achieved.
Framing with Glasses Notice: The EyeKup improves contrast and focus refinement by sealing peripheral light. When worn with glasses, any eyecup adds eye-to-finder distance, which may limit visibility of wider framelines (28mm, sometimes 35mm). Results vary by eyewear fit and facial anatomy.

A Perfect Match for My Leica M11 Monochrom
I’m really impressed with this eyecup. Not only does it look beautifully made, but it also serves a practical purpose—I wear glasses, and it provides a comfortable buffer that helps protect my lenses from rubbing against the camera.
What I particularly love is the brass with black patina finish. It matches beautifully with the rest of my camera accessories and my entire brass-and-black-patina collection, giving the Leica a cohesive, timeless character.
It’s one of those small accessories that combines function, craftsmanship, and aesthetics perfectly. It feels like it belongs on the camera rather than simply being an add-on.
A great upgrade for anyone who appreciates both the Leica shooting experience and beautifully crafted accessories.
Excellent product, manufactured and shipped by a throughly professional and friendly company. Due to the rubber used on this eyecup, I'm finding that I don't get the smearing (and hopefully no more scratches) on my eyeglasses, which have been a problem for me over many years of using Leica M cameras. So impressed, I'm thinking about buying another one for my Leica M-P 240.
Thank you so much for your thoughtful review, Dave! We’re delighted to hear the Slim M-EyeKup has made such a difference by reducing smearing and helping protect your glasses. It’s exactly the kind of improvement we set out to achieve. We truly appreciate your support and look forward to equipping your Leica M-P 240 as well!
I bought this for my original M6. It fit perfectly and looks amazing on the camera! Highly recommended.
Thank you for your great feedback, David! We’re delighted to hear the Slim M-EyeKup fits your original M6 perfectly and complements the camera so well. We truly appreciate your recommendation!
Great stuff! Now living forever on my M3.
That's what we like to hear! Once it's on the M3, it's not going anywhere. Thanks for the great feedback, really appreciate it!
It's a product that greatly improves the rangefinder experience.
Thank you so much, Luiz! That’s exactly what we designed the Slim EyeKup for. Really happy to hear it improved your rangefinder experience. Enjoy shooting!
Used the black one on my M6 and it is a perfect fit. My glasses now have a comfortable place to rest and with a little pracice I can still see the entire finder.
Thank you so much, Dave. This is exactly the kind of experience we hoped to create with the Slim M-EyeKup. We are especially glad to hear it gave your glasses a comfortable resting point while still allowing you to see the full finder with a bit of practice. Thank you for sharing your experience on the M6 and for trusting us with your setup!
Great accessory - seconds to add and now my glases are well protected. Finish is nice (i got the black) for my M11-P and I also got the other size for my M6.
Thank you again, Dave! We truly appreciate you coming back and trusting us with both your M11-P and M6 setups. It is great to hear the M-EyeKup was quick to install and delivered the comfort and protection you were looking for while shooting with glasses. And thank you for noticing the finish as well. Support like this means a lot to our team.
Great product. High quality, looks great on the camera
Thank you, Neil! Quality and aesthetics go hand in hand for us, we want our products to not only feel premium but also look right at home on the camera. Really glad it's hitting both marks. Enjoy it!
Delivers on its promise. So much more comfortable woth glasses especially as km left eye dominant.
Thank you so much for your thoughtful feedback! We’re delighted to hear the Slim M-EyeKup delivered on its promise and made shooting with glasses much more comfortable. Knowing it’s helping left-eye dominant photographers means a lot to us. Thank you for your support!
