can we petition RJ to make a BMPCC focal reducer?

Hi everybody, almost ready to order my M42-version and have a question for another one:

Could I use my Hexanon lenses with Konica AR mount via a AR->Leica-M adapter on the Leica-M-RJ adapter on my Blackmagic Pocket? The flange distance should be alright for this.

Does the RJ lens turbo come with both front and rear caps?

@Vitaliy_Kiselev, I received mine a few months ago and it doesn't have a tripod foot. It is the Nikon G.

Can I buy it separately?

I'm having trouble adjusting the infinity focus, I can focus to infinity but its not at the end of the focus throw where infinity is marked on the lens. It's a little bit before the infinity mark and if I keep turning the focus ring all the way to infinity the whole image then goes out of focus. I've tried adjusting the RJ adapter and used its full range of adjustment but cant get it to work right.

Anyone had similar issues?

I would be disappointed if mine came without that tripod foot.

Does anyone know of a cheap version for the BMPCC being planned? With its 0.58x factor glass?

It is possibility, but I do not know any exact date.

A reasonably priced (passive) EF->BMPCC adapter would be a huge thing! YES PLEASE! Also, the BMPCC is not such a niche product anymore, a LOT of people bought the camera during the summer sale and now can't justify spending more on a focal reducer (the metabones one) than they did on their new camera :) The problem is, the demand is there NOW, hard to say if it will still be there in 6+ months (or however long the design & production of such an adapter usually takes).

@Boncrek

I want to know the weight of everything in my rig so I can manage my weight distribution.

What exactly is "weight distribution"? You want to know balance weight or what?

I never heard about rig that is remade for each different lens :-)

What is the weight of the new nikon to m43 version?

Is it really important? :-) As your lens will weight more.

Is the tripod foot arca compatible like the metabones?

Yep.

Just received my RJ Speed Booster EF to m4/3 and I am very happy with the results! A non scientific test (very lame to be true) with some lenses in my desk office with terrible lighting and awful conditions. But I did get the results & answers I was looking for. First thing I noticed was that the Samyang 35mm Cine version was much better wide open. Yeah!!!

GH2 Settings - Driftwood's Moon T7 24p @140Mbps

Lenses Samyang 35mm T/1.5 VDSLR Canon EF 100mm f/2 Carl Zeiss Jena Tessar 50mm f/2.8

PNG Capture Frames in Full HD 1080p with 2 crop frames at 200% of center & edge.

Thanks Vitaliy for the offer! Check photos on Lightroom to compare the differences. Hope it helps! Enjoy . . .

I shot everything on the Samyang 35mm 1.4 because it is a really sharp lens across the whole frame. In terms of chromatic aberration yes all of the speed boosters seem to exhibit this problem.

The newer Nikon 85mm 1.8G, 24-70, 70-200 VRII etc all have the newer coatings and help reduce flare etc. The Samyang 35mm 1.4 is super sharp but does not have the same coatings so when you shoot with this lens with a high key backdrop etc you will see a loss in contrast. The newer Nikons and Art Series Sigma lenses perform extremely well with very little loss in contrast.

I like Nikon G series lenses but I am migrating towards the Sigma Art Series lenses. The only downfall about the Sigmas is that they are not weather sealed but other than that the build image/quality is superb. To answer your question IMO the newest modern lenses be it from Nikon/Sigma/Tamron/Panasonic etc have better optics then the older Nikon lenses.

There was another member on Personal View that said that the newer Panasonic lenses are superior (optically) to the older Nikon lenses. At that time I did not believe him, part of this was because I love the build quality of the older lenses and did not shoot any charts or high key backdrops etc. I only shot real world subjects so did not notice a difference, however when I shot the charts and high key backdrops I then realized what he was talking about.

That being said the older lenses are still very good but optically I concede that they are not as good as the newer lenses from pretty much all the manufacturers. To play devils advocate their are those who will say that sharpness and contrast is not everything and sometimes you want that soft flattering look, well for me I want the lens as sharp and contrasty as possible and would prefer to add softness etc etc in post if I choose to do so.

So moving forward for me it will be Sigma Art Series 18-35 F/1.8, 24-105 F/4, 35mm F/1.4, 50mm F/1.4 hopefully they will release the 85mm and 70-200 Art series to complete my lens kit. The Tamron 24-70 and 70-200 VC is excellent optically, but the build quality is not up to par in comparison with the Sigma Art Series lenses.

Attached is a test picture in my studio with the Sigma 18-35 1.8 @1.8, I am purposely pointing the camera at the hair light (10:00 upper left) there is basically no loss of contrast with this lens. This lens is superb, sharp images and excellent build. Anyway this is basically what I am talking about so hopefully you can get an idea from the attached picture.

I am asking, because I read that the BMPCC is a very niche product which is not very widely used and it would not be profitable to make a special speedbooster for it without large price.. Let us know when you know more!
