Like OH said, check eBay. I've seen one that was metal once and was 52mm. For hiking, I'd go with center-pinch caps. They're a buck, hold fast, and are plenty durable. Also, if you're out throughout the day and the temperature changes, your cap may swell or shrink. With a center-pinch cap, that's no big deal. With a screw-in cap, that could make taking a photo difficult. |
I do have all center-pinch caps. But they have a tendency to fall off easily, especially when crammed into my backpack, and then that leaves the lens vulnerable.
With metal caps the edge is extremely sharp, and since the material is harder than glass it can scratch easily if your hand slips while taking it off. If the screw-in cap were made of plastic and you accidentally scraped the surface when taking the cap off (for example, trying to unscrew the lens while walking) it would do a lot less damage to the lens surface ... _________________ Canon EOS 6D | Canon EOS 60D | Canon EOS-M | Voigtlander Nokton 1.4/35 | Zeiss Distagon C-Y 4/18 | Zeiss Distagon ZF 2/28 | Samyang 1.4/35 | Zeiss Planar C-Y 1.4/50 | Zeiss Planar C-Y 1.4/85 | Zeiss Makro-Planar C-Y 2.8/100 | Zeiss Sonnar C-Y 2.8/135 | Nikkor ED Ai-S 2.8/180 | Canon FD SSC Fluorite 2.8/300 | Tair-3S 4.5/300 |
