anyone pull the trigger on this new lens turbo? i'm tempted.

The mft to Nikon isn't avail yet but I might on the Metabones if it doesn't come out soon

@Psyco Yeah man, I'm stumped too. Might just grab a Metabones instead. I'm sure I won't be the first.

I think that the most interesting focal lenght on the Mitakon Lens Turbo + GH2 could be 35mm: we can get in this way, using a cheap 35 2.8 lens, a 50mm eq. FO, similar to 25mm lens (like Panaleica or Nokton 25), with an extra stop (a 35 2.8 with Mitakon on GH2 should perform like a 25 f2 lens). I hope it will be a nice low-budget solution, since it is very hard to find cheap old manual glasses for this focal lenght apart from Vivitars/Kiron 24/28mm 2.0-2.8, which have evident perspective distortion too.

Ps. I love my little Vivitar Komine 28mm 2.8 , Pentax mount, on my GH1, however, while the FOV is 50mm Eq, it has the distorted perspective of a wide lens, and not the magic 50mm look (flat, but not exaggeratedly).

@Vitaliy_Kiselev I mean that using my Vivitar/Komine 28mm 2.8, Pentax K mount, I usually have a "grand angular effect": distortion on the faces, distortion on the windows (which appear a bit "bended"), and when I shoot a scene where the subject is in front of me and at the same time there is , for example, a painting on the wall behind him , the painting appears very small while the guy very big. It is a problem of my vivitar 28? I hope not! XD

Ok thanks, I will try to correct my framing then...If I have futher problems I'll post in a separate topic some still ;)

Over on dpreview they are saying the blue dot is still an issue with the new adapter.

Hmm. It needs more testing, I doubt that they claim it fixed if it is not. It is quite competitive field now, so needs double checking.

Or they can just change the name to something like "Special Blue Dot Lens Flare Optics" and say they did it on purpose, like some other non named company :)

I have a simple question about Mitakon Turbo Lens and Speedboster: according to the Flange focal distance, it would be possible to buy a Turbo Lens CANON FD mount (which is 42.00 mm )and then simply buy generic adaptors FD->OM, FD->Minolta, FD->M42, FD-> PK...etc, (like this one http://www.ebay.it/itm/M42-SCREW-Lens-To-Canon-FD-Mount-Adapter-/280551766515?pt=US_Lens_Adapters_Mounts_Tubes&hash=item41523039f3 ) Is this correct?

@Vitaliy_Kiselev Sorry, but I don't understand..could you please explain the reason why it is not possible to do it? I will be grateful to you :)

@Vitaliy_Kiselev Ok, thanks, now I understand :) There are lots of cheap converter like FD-m42, etc. Since FD is the shortest flange focal distance available on Metabones/Mitakon, I think that it would be a good choice to buy a Mitakon FD and then cheap adapters FD-> OM, PK etc just to test our vintage lens collection (expect Konica A/R lens, which have a too short flange focal distance ) I realize that more adapters can complicate things..but I think it's worth to give a try since their price is pretty low... :)

The makers of these sorts of adapters claim that their condensing nature actually increases sharpness. For my usage, sharp lenses produce sharp results with the Lens Turbo, although even sharp lenses do see some softness towards the far edges. Softer lenses (like the Tamron 14mm in the edges, frankly) produce softer results. Lacking a glassless adapter to compare, I uploaded a full-resolution un-sharpened image taken with my Super-Multi-Coated Takumar 100mm f/4 macro lens, which is a consistently sharp lens.

Likewise, lenses which vignette without the adapter also vignette with the adapter.
