Viltrox EF-M2 II Reviews

Makes OM-1 Malfunction!

By Baron
Rated 2 out of 5
Date: 2022-08-07

The good news is, it physically fits on the OMDS OM-1, which has slightly less clearance than for example the OM-D E-M1 Mark II. Many products that fit on the E-M1.2, like Metabones, won't fit on the OM-1. So it's good that it fits -- and it just barely does, with a fraction of a millimeter clearance. But it doesn't work (even with firmware v4.0 which I installed before using). The camera just blinks and freaks out. I tried it on an older PEN E-PL7 and that camera handles the adapter fine, but the OM-1 isn't happy with it. This concerns me... I'm not trying again. I just feel lucky that I didn't fry my multi-thousand-dollar camera, and I won't take that kind of risk again in the future. In my opinion you use this product at your own risk. I wish I'd thought to give myself that advice a week ago, but as far as I can see no harm was done, so I'm wiping my brow and taking a few calming breaths.

Tengo una BMPCC4K y el poder adaptar los lentes Canon a BlackMagic eran mi dolor de cabeza. Cuando compr este adaptador qued fascinado, no solo por el material sino tambin por la calidad que ofrece.

Why don't these come with the focus already adjusted.

They work well and are so much cheaper than metabones. Almost 100% chance that you'll need to adjust the focus on this to reach infinity on your lenses. Theres some youtube videos that explain how. I can't work out why it's not adjusted from the factory?

Great!!!

Freezing issue resolved

By James

I wanted to address the freezing issue in my review with the GH5 and explain what caused it and how I fixed it. YMMV. TLDR: Tighten all the screws on the adapter, especially the ones on the camera attachment side. Found a loose screw there and tightened it. This seemed to solve my freezing issue. Most of the time, this lens adapter worked flawlessly with my GH5 and Sigma 18-35. One day my camera got bumped in my bag pretty hard, and the adapter came off the camera. I checked for damage and couldn't find anything. A couple weeks later, I noticed my camera freezing and giving me error messages. I would have to remove the battery and put it back in in order to use the camera. I originally thought it was a battery issue and ordered a replacement. When the problem didn't go away with a new battery, I further examined my camera, lens, and adapter. When I removed the adapter from the camera body, I found a loose screw sitting inside. Luckily it didn't damage the sensor. Found out that the screw belonged to my Viltrox adapter. I reattached the screw, tightened all the others, reattached my adapter and lens to my camera. Voila! No more freezing! I guess the bad connection was causing the error. Its been 2 months and have had no more freezing errors *fingers-crossed*

Not great - Viltrox customer service even worse

I made a huge jump from my hacked Panasonic Lumix GH2 to the BMPCC 4k. I already had a decent FotodioX lens adapter (which has been great). I used that on the new BMPCC4K and thought nothing of it but decided to try this after several recommendations. I have VERY little wiggle room when it comes to trying to focus with any of my lenses. From my most expensive Canon EOS lenses to my knockoffs that are actually extremely sharp on my GH2 with the Fotodiox. That also being said, I couldn't update the firmware. I tried 6 different usb cables and none worked. I own 3 Macs so I sent a message to Viltrox customer service and their response was. Try a windows computer. When I said that wasn't an option for me, they replied: You can try. Amazing. I likened my issue to possible user error but there are so many message boards and user complaints online that I just had to let someone else know who's considering it. If you're getting it for older cameras, maybe this is the way to go. For the BMPCC4K... not one bit.

The good & the bad

I intended to use this for my BMPCC4K to the sigma 18-35 1.8. I saw how expensive the metabones adapter was and did some heavy research for the comparison. I ended up purchasing the viltrox obviously & when I got it and tried using it , the adapter was extremely tight and very alarming how hard it was to take back off . Almost to the point where if I would use. But more force it would definitely damage the camera itself . Now as far as for how it functions? It gets the job done .. meaning it looks great for whatever lens you plan on using .. but understand it's full potential isn't being used . In my experience I had to manually focus & the lens had a lot of play when attached to the adapter which is not a good feeling when your best lens is being held by a adapter that may or may not come off .. As of now I switched to the metabones adapter and yes it is overpriced in my opinion but I can tell yiy the difference is major and we'll worth it .. sharper , cleaner , no issues at all using straight out the box. If your looking for a adapter for the fraction of the price & have the patience for adjusting the infinity focus . Then it's absolutely what you want to go with.. it's not a terrible adapter and it's not the best but it is good.. Hope this helps

I have not seen any specific reviews on the speedbooster being used with that camera, but I don't see why it wouldn't work. If you are referring to the g100 lumix camera. It should work fine, as it is micro four thirds mount. Same as all the lenses too.
