johnwe Posted January 14, 2014 Share Posted January 14, 2014 does anyone have one? i'd love to see a large still image to see how sharp it is edge to edge. Quote Link to comment Share on other sites More sharing options...
Orcadia Posted January 24, 2014 Share Posted January 24, 2014 I got the adapter friday last. testing, no definite conclusions as of yet.but pretty good so far. Setting up on a 5D Mrk3, full frame. Very easy to use. doesn't really flare that much. You can pull focus. you can switch out lenses pretty quickly on the right rail system. Its heavy but you can shoot hand held. (40mm canon pancake very practical) So far very slight vignetteing on the sigma 35mm. Big advantage seems to be possibly to shoot wide open,( f 1.2 on 50mm canon) stays sharp For anyone buying; It won't really connect properly without the Letus filter rings, the lens support adapter is essential but doesn't really fix in place it just supports. Also warning it has a quirk, it falls in to 2 pieces when not tightened, we almost dropped the lens. Warning; the rear element of adapter moves quite a long way towards camera so be careful it doesn't end up touching the glass of your taking lens. set up with adapter set to maximum distance (another reason to buy the lets adapter i guess.)

johnwe Posted January 24, 2014 Author Share Posted January 24, 2014 Thanks for sharing this info. Would love to see some footage or images when you find the time. Quote Link to comment Share on other sites More sharing options...
Stuart Hooper Posted January 26, 2014 Share Posted January 26, 2014 I'd really like to know more as well. I need to upgrade from the LA7200 and I am ready to pull the trigger on something, but online results from the Letus have been lukewarm at best and there are weird rumours about the amount of squeeze shifting, etc. Images, samples and more thoughts would be lovely, and what you've posted is helpful for a start, makes me cautiously optimistic.

Orcadia Posted February 2, 2014 Share Posted February 2, 2014 few (actual) frames from latest tests, sorry not much time to post, will try more next week. Letus adapter , 3200 iso, canon5D3,ML RAW dolly tripod, 50mm 1.2 and very intersting retro 135mm canon soft focus lens going pretty well, still to early to call, but going well. ignore lens description, just a formating problem.

Orcadia Posted February 3, 2014 Share Posted February 3, 2014 Very rough test Anamorphic letus adpter Canon 5DMRK3, ML RAW, 3200 iso, film convert used tripod on dolly Sigma 35mm 1.8 , lenses 50mm at 1.2, , 100mm macro at 2.8 all wide open. Letus anamorphic adapter. very rough first tests. very low light full frame 35mm (Thanks JB) https://vimeo.com/85719835 Christina Ava 1 Quote Link to comment Share on other sites More sharing options...
Michael Van Ostade Posted February 3, 2014 Share Posted February 3, 2014 Which coating did you order on your letus lens? Quote Link to comment Share on other sites More sharing options...
Orcadia Posted February 3, 2014 Share Posted February 3, 2014 letsu adpter medium flare single coated. Quote Link to comment Share on other sites More sharing options...
Sean Cunningham Posted February 3, 2014 Share Posted February 3, 2014 That 100mm shot looked to have some convincing bokeh! Quote Link to comment Share on other sites More sharing options...
Stuart Hooper Posted February 4, 2014 Share Posted February 4, 2014 Thank you for this. If there is anything you need to facilitate more testing sooner than later please let me know. I've offered to pay for someone to rent this out in LA for a day to get more tests but have no takers. Really on the fence about the sharpness and functionality with close-up shots and having a hard time finding information online and Letus is very, very quiet.

Orcadia Posted February 4, 2014 Share Posted February 4, 2014 Very CLOSE UP SAMPLE funny we were just asking ourseleve s same questions. Attached 100mm macro/close up shot through letus adapter. Its very good but would be sharper without the letus adpater. Letus does permit very close up with some loss in sharpness but macro not possible at least with configurtion we were trying) still no conclusive tests, but so far its great system, it seems to lack the character and soul of the true anamorphic lenses but this is a trade off against a system that works very straightforwardly; no dipoters etc. . s Quote Link to comment Share on other sites More sharing options...
Orcadia Posted February 4, 2014 Share Posted February 4, 2014 just processed RAW to video. results very good indeed. far better than initially thought. all working perfectly to just about 35 cm distance. 2 second full rez quicktime RAW ML 5D mrk3 100mm macro canon https://dl.dropboxusercontent.com/u/89252080/letus_100mm_crop_stretch.mov.zip also adding to previous post ;this is what frame looks like without adapter , Canon glass YEAH!!.

Sean Cunningham Posted February 4, 2014 Share Posted February 4, 2014 If you were to shoot with and without an Iscorama, a Kowa or a B&L the shot from the spherical taking lens alone would be sharper. What's your point? Welcome to anamorphics. Use a diopter. Profit. Quote Link to comment Share on other sites More sharing options...
Orcadia Posted February 4, 2014 Share Posted February 4, 2014 No idea about any of that. Never used any other anamorphic system. just trying to give a bit of information back to forum. Reporting as I see it. Quote Link to comment Share on other sites More sharing options...
Sean Cunningham Posted February 4, 2014 Share Posted February 4, 2014 Well, the Letus is a "true" anamorphic lens. As such it's just a given that sharpness with the adapter is going to be lower than without. You are making a conscious decision that the addition of horizontal FOV and the character inherent in its distortion are worthy trade offs to clinical sharpness when you choose to go with anamorphic. The same shot will always be sharper without the anamorphic, no matter the anamorphic(*). How close you're able to get with still workable sharpness (which is going to be fairly subjective) before being aided by diopters or perhaps a different taking lens is still a very helpful experiment though. edit: (*) this might seem to create a slight paradox when comparing anamorphic 35mm to Super-35mm, where anamorphic has much more detail and delivers a sharper, more detailed release on film or digital. This is because for a given final aspect ratio the anamorphic photography uses the entire height of the film negative where Super-35mm crops to a smaller window of the negative to achieve the same aspect ratio. While that may simply be trivia it has the same implications for anamorphic DSLR photography when you're shooting for an intended aspect ratio and not simply comparing still for still. 2.35:1 with an anamorphic adapter, despite the hit to sharpness, can ultimately be better, sharper and with more detail than 2.35:1 cropped out of the sharpest taking lens you'll find (once you alter your taking position to achieve similar framing and then either blown up the spherical or reduce, therefore oversample, the anamorphic).

Thanks. My main interest is indeed increase image information that the anamorphic on dslr provides. ML on 5Dmrk3 also throws another element into question wether the 3x crop factor is better than using anamorphic, in respect to quantity of information .

Stuart Hooper Posted February 4, 2014 Share Posted February 4, 2014 Procter thank you a million times over. I think Burnet may have taken your comment a little harshly...while we know anamorphic lenses are going to decrease sharpness somewhat I think I understood what you meant and/or where you are coming from. I would not expect Macro close focus either, just hoping for regular close-ups. However your 2 second clip is impressive. (sharpness wise...just FYI I think you un-squeezed it too far) A little more of this and you'll have made Letus $2,700 bucks...please keep it up anything else you can share!

au8ust Posted February 5, 2014 Share Posted February 5, 2014 I've seen an introduction video just once so I'm not remember the focus correctly. Do you focus on the anamorphic lens or the taking lens? Quote Link to comment Share on other sites More sharing options...
Sean Cunningham Posted February 5, 2014 Share Posted February 5, 2014 Taking lens. But there is, I believe, a close-focus adjustment on the anamorphic itself that reduces dependency on diopters Quote Link to comment Share on other sites More sharing options...
Sean Cunningham Posted February 5, 2014 Share Posted February 5, 2014 ... I think Burnet may have taken your comment a little harshly... This is true. My apologies for that, procter. Quote Link to comment Share on other sites More sharing options...
