ngemu Posted April 22, 2020 Share Posted April 22, 2020 I've seen some stunning iphone video footage using these relatively inexpensive anamorphic lens. I was curious if it was possible to use these anamorphic lenses on my Canon ef-m 22mm pancake lens, which has a small front element just like a cellphone. Some manufactures use a rear 17mm filter thread like moondog or ulanzi so its possible to use a step down ring of some sort to secure it on the lens itself...although I'm curious if the distance between the front element and the filter would matter, and how much vignetting will be produced based on the size of the front element and the focal distance. Does anyone happen to have one of these cellphone anamorphic lens that they can test on their camera? Quote Link to comment Share on other sites More sharing options...
leslie Posted April 23, 2020 Share Posted April 23, 2020 there was another similar topic a little while ago. Someone was looking at using the camera phone anamorphics in front of their lens no idea how it went. i have the letus anamorphic for gopro. It screws to the gopro 4 housing. Whoever made the post thought the letus had the widest opening amongst the camera phone anamorphics if i remember correctly. If i can find my digital calipers i will measure it up i might even find the tv remote if i'm really lucky 🙄. At the moment if i run a tape across the top i measure a 22mm opening. how that would vignette i am not really sure. for posterity, i could cobble something together but that wont happen today. ngemu 1 Quote Link to comment Share on other sites More sharing options...
heart0less Posted April 23, 2020 Share Posted April 23, 2020 It's already been done quite a few times and looks quite good, actually! Don't worry about the distance between your lens and the anamorphic adapter - as long as it's not some crazy 2 /3 cm, it won't really matter. Step up rings are your friends! Here are some videos: ngemu 1 Quote Link to comment Share on other sites More sharing options...
leslie Posted April 24, 2020 Share Posted April 24, 2020 thumbs up, heart0less your all over it. But i think i will have a play with mine anyway for my own personal knowledge heart0less and ngemu 2 Quote Link to comment Share on other sites More sharing options...
ngemu Posted April 25, 2020 Author Share Posted April 25, 2020 Holy... Cant believe it worked. Camera: Canon eos-m Lens: ef-m 22mm f/2 Filter: Ulanzi 1.33x anamorphic Settings: 1:1 Full sensor readout at 1736x1158, mcm rewire 1080p, upscaled First shot was stretched using 1.33x, second shot was stretched using 1.5x Upscaled final footage to 4k Still playing around with recording and export settings and this is new to me. The filter is tapped onto my lens so not everything is aligned at the moment. Some issues with focusing to infinity heart0less 1 Quote Link to comment Share on other sites More sharing options...

In fact, you totally convinced me to buy the Ulanzi myself and put in front of a 25/1.8 CCTV lens, hahahahha May I know where did you buy your copy? Could you post a link to it?

I bought it on ebay for 30 USD. I did another test today, its actually quite blurry if your shooting at a distance. heart0less 1 Quote Link to comment Share on other sites More sharing options...
leslie Posted April 26, 2020 Share Posted April 26, 2020 what do you call, at a distance ? 1m, 10m, 100m Quote Link to comment Share on other sites More sharing options...

You may add some low strength diopters (like -1 / or +1) if you want to get more sharpness out of it. It's a fixed focus anamorphic attachment and most likely the focus is set to around 5 - 10 meters. You can't really see it on a phone due to its small sensor and almost infinite depth of field, but when you put in front of a proper camera, then it slowly becomes an issue. Nevertheless, I think it looks great. Really! The majority of wide anamorphic lenses (Cooke 32 mm, Kowa 40 mm, etc.) has quite poor corner quality - and that's what people look for.
