RJ Lens Turbo m43 adapters

davidp158

ICProductions - Hmmmm, that center focus issue is discouraging. Your Umphrey's MeGee shots look good, though.

Will there be a BMPCC Version of the Lens Turbo?

I do not know for now, may be. It is just useful to understand that whole BMPCC sales are much smaller than sales even of single m43 or E mount cameras.

Will there be a BMPCC Version of the Lens Turbo? Would be great to have an alternative for the expensive metabones bmpcc speedbooster...

With a small sensor you'll loose resolution to diffraction anyway. If the blue dot is only seen after f11, it's kind of a non-issue to me!

Here is a piece i'm working on using a G6 with a RJ speed booster (notice the blue dot?) and samyang VDSLR lenses and a Takumar smc 50mm. I plan to get the samyang 35mm asap to replace the Tak because I have intense gold color shift :/ (almost corrected in this wip render)

Overall the RJ has great sharpness but if you use it at f14-f22 you will likely have this blue dot issue. Use ND's when possible to keep the aperture open!

Wides are most critical for flange distance, but it could also be that your Tokina is a bit off in itself – they have quite some sample variation. But with all the adapters you use I'd check flange distance first.

ICProductions

Ok - I saw a post saying adjusting the back focus/optical block is possible, but no actual directions on how to do it. Also - my other lens seemed to be just fine - should i be concerned that after adjusting for the tokina - those would not work?

ICProductions

Here are actual still showing the issue with the Tokina 11-16mm, all wide open. Pretty bad if you ask me! Is there a back focus? Or is this adapter faulty? Or is this normal? Even at 14mm, it's not usable...

First picture is @ 11mm - focus is at .3m/1.0ft Second is @ 11mm - focus is at Infinity Third is @ 14mm - Focus at .3/1.0 Fourth is @14mm - focus at Infinity

Ok! So I've had my RJ-EF for a week and a half and have shot alot of photos ( 3 or four concerts worth) I've had great success with my Tamron 24-70 f2.8, Vintage Nikon 50mm 1.4 and Vintage Pentax 135mm f2.8 (i'm in love with the lens now! ) on both my GH3 and GH2. I decided on the EF mount, as I have a bunch of nikon glass, and am using Nikon f/g to EF adapters. I've attached a few shots!

I'm having problems with focusing though, with my recently purchased Tokina 11-16 f2.8. The lens works great with my standard Nikon to m4/3 adapter, but when on the RJ at 11mm, the center is SUPER soft, with the edges sharp - AT ONE FOOT ( it seems that the focus scale is flipped now for some reason?) When I focus to Inifinty on the scale everything is out of focus! This all stops when I zoom in to 14mm (minus the backwards focus scale).

Please! Anyone have any insight on this? Could it be the cheapo Nikon to Ef Adapter? What - if any - is the next best Nikon (g) to EF adapter to the novoflex?

Tha is correct, you don't see those lenses often, only on marketplace or ebay. But i have a handfull of these, would be nice to turn my 50mm 1.8 carl zeiss planar to a 1.2, never seen before on these. :)

Rollei QBM mount to M43 RJ speedbooster adapter in the pipeline?

Something tells me that it is very rare mount :-)

Hi Guys, i have a new question here.

I like to know if there will be a Rollei QBM mount to M43 RJ speedbooster adapter in the pipeline?

It would be awesome to see some of the rollei/carl zeiss lenses shine again with more speed.

@ehr I'd like to know as well.

I ordered the 14th of Feb and it came in Mar 3. Got some shots and they will be up soon!

Just ordered a RJ passive Canon EF (EOS) adapter. I am thinking about using one of these for the adapter: http://www.ebay.com/itm/Metal-Tripod-Collar-Mount-Ring-A-W-for-Canon-EF-70-200mm-f-4L-IS-USM-Lens-/150813887331?pt=US_Lens_Adapters_Mounts_Tubes&hash=item231d354b63

They are available in different diameters. Does anybody know the diameter of the RJ Ef adapter?

thanks.

Thanks a lot Vitaliy :) !!

If I buy a Lens Turbo "Pentax K lens to Fujifilm XF", exist a "Fujifilm XF to M43 adapter" ? And if exist, it is possible ? Sorry for bad english...

You can do something like it. If you go slightly back you'll see discussion about using multiple adapters and minuses associated with it.

Danpow

Hi everybody and sorry for dumb question. I would like to use Pentax K lens with "Lens turbo" and my GH2. I know that for now there is not a model for this combination. If I buy a Lens Turbo "Pentax K lens to Fujifilm XF", exist a "Fujifilm XF to M43 adapter" ? And if exist, it is possible ? Sorry for bad english...

@Aksel Thanks! Can't wait to get mine!

I'm pointing at light sources all the time.

nomad

The last point is the only one I don't want to avoid at times…

IronFilm

@red_pilll, these things can help which together can make it a non-issue for most:

1) lens hood

2) shoot at a wider aperture

3) don't point it at light sources

Aksel

@kin869 I ordered mine on Fab/12 & I got it Mar/3

kin869

For those who ordered, how long did it take for the adapter to arrive?

Howdy, Stranger!
