DamienMTL Posted November 1, 2016 Share Posted November 1, 2016 Hi, Last week I made some test shots with a GH4 in 4/3 with a KOWA 16-H X2 anamorphic adapter. I love the look of the helios 44-2 but the focal length is often too long. I also used a MIR-1B which is awesome and fast enough without vigneting but I don't think the final 2.35 field of view is wide enough for my needs. I tried to shoot with a FUJINON TV c-mount 25mm 1.4 but this time it gives some vignette on the righthand corners and lacks sharpness. What wide angle taking lens would you suggest to fit inbetween with a nice style and without significant vignetting? The wider the better. Thanks a lot Quote Link to comment Share on other sites More sharing options...
Justin Bacle Posted November 1, 2016 Share Posted November 1, 2016 You should be good (vignette free) with a 35mm, what is wrong with the mir-1B ? If you need wider if you vignette at 37mm, you can go with a 40 or 45mm. I can reccomend the Minolta 45/2 "pancake" lens. but there are a number of equivalent lens out there Quote Link to comment Share on other sites More sharing options...

But I don't think it's wide enough with the M43 crop factor. (FF 75mm Anamorphic equivalent). Quote Link to comment Share on other sites More sharing options...
Justin Bacle Posted November 1, 2016 Share Posted November 1, 2016 According to tito's hfov calculator, you should already be vignetting at 37mm, so I don't think you can go wider than that. (BTW, 37mm on a m4/3 sensor with a two time anamorphic gives you a 37mm horizontal equivalent, not 75 ) Quote Link to comment Share on other sites More sharing options...

I'll buy a speedbooster or turbolens M42 probably. It will help. Quote Link to comment Share on other sites More sharing options...
Justin Bacle Posted November 1, 2016 Share Posted November 1, 2016 I can reccomend the lens turbo II (by mitakon) if you can (it's almost as good as the speedbooster). But i'm pretty sure you'll vignette with the mir-1B + speedbooster DamienMTL 1 Quote Link to comment Share on other sites More sharing options...
Grimor Posted November 1, 2016 Share Posted November 1, 2016 I used to shoot with FD50mm+ Speedbooster and get no vignette. But same configuration plus Rangefinder and I get a light vignette in corners. My helios 44-2 (58mm) dont vignette, but cant get perfect infinity focus with kowa 16H wich is esential for the rangefinder to work.

tweak Posted November 4, 2016 Share Posted November 4, 2016 You can shoot nFD 24mm in 4:3 with 16H/GH4 with no vignette. That calculator isn't always right . Justin Bacle 1 Quote Link to comment Share on other sites More sharing options...

Hi Tweak, I was searching the web for how wide you can go with the Kowa 16-h and came across this old conversation. So I bought the Kowa 16-h. But if I want an aspect ratio of 2.39:1 (cinemascope) I get heavy vignette with the nfd 24mm 2.8 on my GH5. Even with the nfd 28mm 2.8. Am I missing something here? Or does the GH4 crop in 4:3 mode compared to the GH5? Thanks Quote Link to comment Share on other sites More sharing options...
