Qs-C Metal Silver Lens Cap Front Cover Compatible with Leica L39 E39 Caliber Lens Voigtlander Zeiss Summicron Summaron Summilux Elmar Elmarit Jupiter, Internal Diameter 42mm(1.65in) (Silver)

Fits perfectly, tight but not too tight, finish is excellent and matches my vintage Summicron.

The look is super. It looks like original issue equipment. The friction material on the inside give the hold of the cap to the lens a very secure feel Someone took a lot of time to produce a beautiful, needed product for a tiny market. Thank you. It is a very nice product

fits more snug than the original leica m elmarit 28mm lens case, when i put a 39mm uv filter on.

Sticks to my 35mm hood and is very sturdy. My only complaint is it's such a tight fit it sunctions onto my lens and can be a challenge to remove. Im keeping it but really im using a clip front cap most of the time.

Looks just like an original Leica for a 1/10th the price.

The lens cap fits perfectly and looks great on the Leica Summarit-M 35mm F2.8 lens when the hood is not attached. I put a Leica UV filter on it but have no problem using this lens cap. I definitely recommend it if you’re not using a metal hood and are looking for a solid alternative lens cap.

Would be a great product if it fits….But it is too big if you want to put your filter on. Needed to add a soft sponge sticker on the inner to fit.

Perfect fit and good quality at a reasonable price. Highly recommended.
