Duncan McDougall Posted October 8, 2022 Share Posted October 8, 2022 Quick question for an expert. Is it possible for a Switar AR lens to be converted or collimated into an RX version that will work with the Bolex reflex prism? The lens in question is a Switar 16mm 1.8 AR. Thank you.

Premium Member Dom Jaeger Posted October 9, 2022 Premium Member Share Posted October 9, 2022 No. It’s not a question of collimation (back-focus adjustment), it’s different optics. If you shoot with the lens stopped down past f/3.5 it shouldn’t matter much. There’s a relatively affordable RX one on eBay now (a little beat up but optics might be ok):https://www.ebay.com/itm/255689434281 Most seem to have been bought up by the Calkovsky “buy it on eBay then sell it for twice the price on eBay” store, but if you’re patient you can find them cheaper.

Duncan McDougall Posted October 9, 2022 Author Share Posted October 9, 2022 Thank you very much. I suspected that the optics were different. Thanks for clearing this up. I will check out the EBay listing. Link to comment Share on other sites More sharing options...
