DanielVranic Posted May 23, 2019 Share Posted May 23, 2019 Hey everyone. I am picking up a P4K next week and I am using the Sigma1.8 Zooms. I plan on using the glass full manual, but the aperture is controlled electronically. I really do not want to spend 650$ on a Metabones, as I am never using the AF, but still need the electronic connects. What does everyone recommend? thebrothersthre3 1 Quote Link to comment Share on other sites More sharing options...

Avenger 2.0 Posted May 24, 2019 Share Posted May 24, 2019 The VILTROX EF-M2 is cheaper, but it will be optically not as good as the Metabones. And since quality control is lacking, you might even get a really bad one. You can also buy the VILTROX EF-M1, which is the same but without the focal reducer. Let's you control the aperture and do AF without loss in optical quality. Quote Link to comment Share on other sites More sharing options...
Adam Kuźniar Posted May 24, 2019 Share Posted May 24, 2019 Viltrox EF-M2 is optically identical to the Metabones in center of the shot, corners are a bit blurry. However is that worth the difference? If I was shooting a movie for the cinema, I wouldn't skimp on that, but as I'm mostly shooting for youtube and web delivery, there's no way anyone can see the difference and none of my clients ever commented on that. I have it, I had zero issues with it and I think it's worth the price. newfoundmass and andrgl 1 1 Quote Link to comment Share on other sites More sharing options...

tweak Posted May 24, 2019 Share Posted May 24, 2019 Remember there's actually no cheap version of the Ultra .64. Viltrox M2 is a good budget option if you are looking at the Ultra .71x. Quote Link to comment Share on other sites More sharing options...

I mean, is it worth the difference knowing you paid the creators instead a Chinese company that simply stole the design? It’s not like the guy who designed the optics that were copied even posts in this forum. Everything should be as cheap as possible, especially the work you do, you should strive to deliver at lower costs. @Brian Caldwell Quote Link to comment Share on other sites More sharing options...

Also Metabones are not amazingly well made and are over priced IMO. Optically I've not seen any evidence that the Viltrox is inferior.

noone Posted May 27, 2019 Share Posted May 27, 2019 Kipon makes both focal reducer and non focal reducer adapters that work ok and a lot cheaper than Matabones. I had one of the earliest non focal reducer ones (serial number was 77 form memory) and it worked fine for electronic aperture (and AFS too) after a couple of firmware upgrades (was terrible as sold but very quickly became very useable after a couple of upgrades).

newfoundmass Posted May 27, 2019 Share Posted May 27, 2019 I've used both Metabones and Viltrox focal reducers and I noticed minimal differences between the two in terms of image quality, certainly not enough to justify the price difference anyway. The only issue I had with my Viltrox, and it was an easy fix with the supplied tools, was adjust the back to focus better with the Sigma 18-35. I haven't used it but I've also heard good things about the Commlite focal reducer. Quote Link to comment Share on other sites More sharing options...
thebrothersthre3 Posted May 27, 2019 Share Posted May 27, 2019 Lens Turbo seemed to be the closest to Metabones in terms of quality. You can control the aperture manually with a Lens Turbo. No need for electronics if you don't need AF. Quote Link to comment Share on other sites More sharing options...

You can control the aperture manually with a Lens Turbo. No need for electronics if you don't need AF. Or aperture priority. Or wireless aperture through an app. Or controlling the camera through USB. Or being able to accurately tell what aperture the lens is actually at. Or have EXIF.

thebrothersthre3 Posted May 27, 2019 Share Posted May 27, 2019 Measuring exposure is easy enough where you don't really need to know the exact f-stop. Not being able to control through an app is definitely a loss if you do that sort of thing though. Quote Link to comment Share on other sites More sharing options...
ZEEK Posted May 28, 2019 Share Posted May 28, 2019 I was scratching my head between choosing the Lens Turbo II, Viltrox EM2 & The Metabones (For BMPCC). It's a shame the cheap speed-boosters (Viltrox) don't allow for IS or OS on Canon or other Third Party Lens. They almost had it in the bag.
