I hate beeing the one to ask this - but any news on the new batch, especially other mounts? :) I'm desperately waiting for a m43->EF solution (passive) for use with BMCC and GH2 :)

Any idea when the FD to M43 speed adapter will be available?

Great! I am waiting :-)

ps. Will you have plenty in stock or will we have to rush to get one?

@Vitaliy_Kiselev where can I buy it? On special deals? I want to buy one asap.

RJ Lens Turbo PV deal Mini review:

-Purchased via PV Deal

-Came reasonable fast (considering Christmas)

-Shipment was marked as Lens hood, so no Duty charges was applied (UK)

-Built quality is good apart from Lens grease below the aperture ring ( see picture)

-Mounting my Sigma 24mm f1.8 was difficult at first attempt, I needed to push hard. After that was easier with all lenses including Sig 24mm

-IQ in my opinion is that RJ has less sharper image in the centre than Mitakon Lens Turbo, but border to border sharpness is better with RJ

All photos taken in Aperture mode @wideOpen and @5.6 than resized for upload to PV. Sorry for fast moving sun..

Lenses used:

-Sigma 24mm f1.8

-Sigma 28mm F1.8

-Nikon pancake 50mm 1.8

-Tamron SP Adaptal2 90mm f2.5

Don't remember exactly, more or less 12-14 days..

Thanks for the insight @jobless! But that shows me that the Mitakon might be more for me; even though it seems that it has a lower contrast (I think this could be because of the light changes, but I noticed it's always a tad less contrasty in those images)

Just bought the m42 version via paypal, hope everything is alright ;)

I will write a review when it's here.

@gameb that's right, but for me the center is more important then the edges :( I'm actually quite interested how the announced Kipon will work out, yet I'm really wanting a MFT solution for EF quite soon. And Mitakon and this one are pretty cheap, so what :)

I will contact RJ as I don't know if I got a (really) bad copy or if the adapter doesn't work with such a wide lens. (I'm just a bit pissed, as this is the second speed booster clone that doesn't work as advertised.)

Check the adapter, optical block is on the threads and can be adjusted. It seems that it had been misaligned.

Update:

Ok, got a reply and (as Vitaliy sad) the lens elements are adjustable. The problem is, I can screw in and out both lenses (front and rear) individually! I don't know if thats intended? I can also screw them together and then move as a unit.

Adjusting focus will have to wait till tomorrow (I need more light) - I will give an update about sharpness.

One thing: If I close down the aperture to its minimum and point the lens at an angle to a light source, I get a horrible blue dot in the centre of the frame. It is nearly circular and has about 10 edges - looks like some reflection of the iris. @jobless can you test this with your adapter please (stop down and point the lens just missing your computer monitor, best visible if something dark is in the background).

Blue dot. I keep telling everyone these cheap adapters will not work well. It's the glass used. Period. There's no way around it. I know you all want a cheap solution but this is one area to stop wasting money.

It is the glass. Remember we had this talk before. There's 3 levels of glass companies are using for these adapters. The first Fotodiox was the bottom level, all these other ones are level 2 and the Metabones is level 3. That's what helps to push the price up. Well that along with the Metabones name. I'm sure you'll get upset with me and others will say I'm wrong but time and time again we are seeing the same problem with these cheaper versions. This is a fact. And people keep making other excuses.

Trust me, I would rather spend $200 rather than $400+ for one of these if it worked good but they don't. Every knock off I've seen so far has had that blur spot/flare in it.

And playing my own devils advocate and going by your view, maybe it is coating but I do believe the same logic applies. Bottom level, middle level, top level. I do believe Apfos (did I get his name right) had the same problem with his anamorphic adapter.

It just sucks seeing guys wasting money on inferior products especially when they are getting raped in taxes and import fees. Luckily we really don;'t have that in the US but other countries it seems horribly high.
