My new lens cap for the MS-Optical Sonnetar 50/1.1.

I love the pictures that my MS-Optical Sonnetar 50/1.1 can give me, but lately it has been sitting in the camera box in favour to the C Biogon 2.8/35, another stellar lens for completely different reasons.

The reason why I sometimes refrain from using this lens is not because of the optical quality, but more because of the ergonomics of the lens, more specifically, the lens cap.

The lens cap is metallic and sturdy, but it is a screw-on lap that requires several turns to tighten. In addition, the lens hood, while svelte and also sturdy, is again a screw mount. While the lens hood can be placed backward for compactness, it is the only way to unscrew the lens cap. It is nearly impossible to screw the lens cap off or on the lens when the lens hood is placed forward for actual use.

Since this is a F1.1 lens it has a very large first element, and I'd like to keep the cap on it as much as possible.

So I decided to use the Nikon 52mm LC-52 as a lens cap. The filter size of 52mm fits nicely, and the tabs on the lens cap are large enough that I can pop it on and off with ease. I'm not a big fan of filters since there is a decrease in optical performance, I may entertain it for this lens mostly due to the large first element.
