Pentax smc PENTAX-DA 40mm F2.8 XS Lens on film
The Pentax smc PENTAX-DA 40mm F2.8 XS Lens is an impossibly thin pancake lens that was originally designed to go with the digital APS-c Pentax K-01 but as some people have noted it also covers a full 35mm film frame. I needed to find out for myself so I mounted it to my Pentax MZ-6 a camera that I had given away but received back and am very happy about that. I had really under rated the camera, while not built to take a beating like a professional camera, it has all the functionality of one. Back to the lens though. While the lens is very thin it shouldn’t be all that surprising as many 35mm film point and shoot cameras have similar sized lenses that are often even closer to the film plane. As a lens used with 35mm film I can say that it does an excellent job with very little vignetting which is the one thing you might expect to see when using an APS-c lens. The fact that it takes up next to no room in a camera bag and that it can be used on both film and digital really makes this a must carry lens for me.
