Viltrox electronic focal reducer vs. Zhongyi Lens Turbo II Comparison

fatpig — Tue, 13 Jun 2017 07:59:46 +0000

Viltrox came out with the first cheap electronic focal reducer. I got it because I'd like to use some Canon lenses that have no aperture ring. Sadly, corners are not quite as sharp and there is a little more bulging. Also, inside the adapter is less space because of electronics, and some vintage lenses wont fit without cutting protruding pins.

check out these straight-out-of-camera JPGs from the Sony A6500.

I need some help understanding the Speedbooster for M43

magellan14 — Tue, 13 Jan 2015 17:44:59 +0000

I have a Panasonic GH3 and am considering the Mitakon Lens Turbo for M43 to Canon EOS EF. I understand this adapter gives an extra stop of light and allows me to use 35mm glass. My question is, how do I determine what the f-stop will be and focal length of a full frame lens once equipped with the lens turbo? For example, if I attach a Canon 50mm f1.4, would the focal length still be 50mm and the f-stop still 1.4 - or would it be less?

I appreciate your help,

C-Mount Speed Booster?

Brian202020 — Wed, 29 Oct 2014 07:06:52 +0000

Does anyone know of a way to get a Speed Boosted image from a C-Mount camera? I'd rather use one official Metabones Speed Booster with a second adapter than having it all in one generic Speed Booster adapter, but I'll take all idea's. Metabones currently makes MFT, NEX/E-Mount, and Fuji X Speed Boosters, so ideally I'm looking for one of those mounts to C-Mount. I'm having trouble finding such an adapter. Thanks.

Contax lenses to Canon EF + Speed Booster

spencerb — Sat, 26 Apr 2014 09:37:21 +0000

I have a Panasonic GH3 and am investing in some old Zeiss Contax Yashica glass. I intend to use the Metabones Speed Booster with them but also want to keep my options open in the future.

Safe Option 1: Buy Metabones Speed Booster in Contax/Yashica -> Micro Four Thirds mount. Connect C/Y Zeiss glass. Profit.
Theoretical Option 2: Buy Metabones Speed Booster in Canon EF -> Micro Four Thirds Mount. Adapt Zeiss C/Y glass to Canon EF mount. This allows me to share lenses with Canon bodies if necessary and also mount standard Canon EF glass to the Speed Booster as well. With the limited range of wide angle Zeiss C/Y glass available this also could make things easier. It saves me buying multiple $400 Speed Boosters.

Question is: Is there any reason NOT to do option 2? I know it will allow a greater chance of error in the adaptors, but will the C/Y -> Canon EF even mount to a Canon EF -> MFT Speed Booster? Is this entire idea completely stupid or have I stumbled on accidental brilliance?

THANKS!

Lenses to use with GH4 / 4K Cameras

JanH — Sun, 09 Feb 2014 13:37:30 +0000

I'm pretty excited about the potential of the GH4 (and I suppose any other 4K cameras at $2,000 or so). I am currently using the GH13, mainly in 720p mode with a variety of legacy full frame lenses. Canon FD, Minolta MD, Nikon, Helios, Pentax etc. These all produce a lovely image, less clinical than the Panasonic 14-140 kit lens, IMHO.

Now with 4k coming along, I'm wondering if these older lenses will have any chance of producing the detailed images that the higher resolution sensors are capable of. Or, whether the way forward would be to use an RJ or Metabones speed booster with these lenses to get the detail/ resolution? It would be a shame to not be able to get the benefits of 4k unless using m43 lenses.

Does anyone have any experience, or opinions on this subject? I'd appreciate any comments.

Looking for zoom lens recommendation with requirements

super_spyder — Wed, 13 Feb 2013 21:43:28 +0000

Hey there I'm looking for a recommendation for a zoom lens with the following things, but am having a hard time finding it. This is going to be used with a Preston FI+Z or C-Motion unit on an FS700, possibly with a speedbooster if it is a FF lens.

-Hard stops on zoom and focus, most likely a manual lens. I'd be afraid of breaking an AF lens even if it has hard stops.

-Zoom and focus rings can't change position while zooming or focusing

-Must be in the "normal" to wide range on the wide end, so anything with a 17 or 24 or 28 or 35 on the wide end. I don't care much about the long end.

-Constant aperture, is a major plus.

I do not need constant volume on the lens, or anything very fast.

Any help would be appreciated.
