Cameron Posted August 16, 2019 Share Posted August 16, 2019 I am trying to adapt a helios 44-2 58mm to my gh4 and I'd like to do this through a speed booster so I don't have to deal with crop. I'm just unsure which speedbooster would do the trick? would the speed booster ultra 0.71x canon ef to micro 4/3 be the way to go? Quote Link to comment Share on other sites More sharing options...

It's the most versatile one. You can adapt almost every mount to EF (apart from Minolta MD and Canon FD). Just get a cheap M42 - EF adapter like this: http://cdn.shopify.com/s/files/1/1415/1308/products/m42-eos-v2-01_800x.jpg?v=1479146995 and you're good to go. Stacking adapters works pretty well, I do it myself all the time. However, I'd strongly advise to take a look at Viltrox EF-M2. It's a lot cheaper and still gives perfect image quality. I did own it and can confirm it's great. Quote Link to comment Share on other sites More sharing options...
Cameron Posted August 16, 2019 Author Share Posted August 16, 2019 Thanks heaps for the help. I'll look into the Viltrox - would this do much different from the metabones speed booster? Quote Link to comment Share on other sites More sharing options...
heart0less Posted August 16, 2019 Share Posted August 16, 2019 No, it wouldn't. Take a look at my post, in which you can see some photos I took with it: Quote Link to comment Share on other sites More sharing options...
Kisaha Posted August 16, 2019 Share Posted August 16, 2019 So, you guys believe that the Viltrox is similar in quality with the Metabones? Quote Link to comment Share on other sites More sharing options...

I haven't had any Metabones product in my hands, so I can't really say if offers a similar quality. All I can say is: I was extremely happy with the Viltrox. Didn't feel any need to get a branded speedbooster. Quote Link to comment Share on other sites More sharing options...
Super Members Mattias Burling Posted August 16, 2019 Super Members Share Posted August 16, 2019 Ive had both and compared them side by side. The Viltrox is sharper on all apertures accept for wide open, has an adjustable back focus (no tools required) and its like a third of the price. The only Metabones I would ever buy is the dedicated BMPCC version (which I currently own), used. Otherwise I would go Viltrox (I sold my Metabones XL).

Cameron Posted August 18, 2019 Author Share Posted August 18, 2019 @heart0less Sorry just one more thing with the M42 - EF adapter you sent, I wouldn't need one with an electronic chip would I? Quote Link to comment Share on other sites More sharing options...
heart0less Posted August 18, 2019 Share Posted August 18, 2019 Yup, there is no need for it to have an electronic chip. Cameron 1 Quote Link to comment Share on other sites More sharing options...
essbe Posted August 18, 2019 Share Posted August 18, 2019 If you are based in the EU I have an EF-mount Zhong Yi lens turbo II (speed booster clone without electronics) that I could sell for 60€. In any case if you're just planning to use m42-lenses it would be cheapest to use a RJ/Jinfinance or Zhong Yi lens turbo, as you don't need any electronics in there. They are both good, supposedly more or less on par with metabones, just check reviews on the internet. In my experience the various speed boosters all work well on m4/3 as the corners are much better on those sensors than on aps-c. The only one I've tested that has been significantly worse than the others is the Kipon Baveyes. Quote Link to comment Share on other sites More sharing options...
Cameron Posted September 9, 2019 Author Share Posted September 9, 2019 I ended up going with the Viltrox EF-M2II with a M42- EF adapter in front of it but I'm having real trouble getting it to work with my helios 44-2? It doesn't focus any further than 30cm and won't go to infinity, so it is like it is a telephoto lens. I should be able to focus further than that right? @heart0less you touched on something about infinity focus in your reference images, is this something you know anything about? Any help would be great Quote Link to comment Share on other sites More sharing options...
heart0less Posted September 9, 2019 Share Posted September 9, 2019 I'd recommend doing this in some gloves, though. Quote Link to comment Share on other sites More sharing options...

heart0less Posted September 9, 2019 Share Posted September 9, 2019 Hmm, then the only other thing that may cause this is your M42 - EF adapter. It may be too 'thick' and that's why it's acting like a some kind of a macro ring. Nothing else comes to my mind. There are no settings that could affect it. Is there any chance you could get some native EF glass and mount it to your Viltrox just to see if it's the speedbooster that's faulty or something else?

Cameron Posted September 9, 2019 Author Share Posted September 9, 2019 I see. This is the adapter I picked up - https://www.ebay.com.au/itm/202465333588 I may have to look into finding some native EF glass to test otherwise I'm out of ideas. Thanks for your help Quote Link to comment Share on other sites More sharing options...
heart0less Posted September 9, 2019 Share Posted September 9, 2019 Well, according to the item description it should allow you to achieve infinity focus.. Without more data there is nothing more I can suggest, unfortunately. Good luck and keep us in the loop! Cameron 1 Quote Link to comment Share on other sites More sharing options...
