since a few days I have a Zhongyi lens turbo for my NEX5N.
So far I have taken a few pics with a Mir 47 K f2.5/20mm, a Pentax K f2.8/24mm and Pentax M f1.4/50mm
with the Mir:
Pentax K f2.8/24mm ( yep, it's a f2.8/24mm. not f3.5/24 as I had erroneously written in the title )
Pentax M f1.4/50mm

Tony I have only used it twice yet, once with Pentax K2.8/24 and M 1.4/50 in the poolhall, just a few takes, and today with the Mir47K and the M 1.4/50 during an afternoon stroll.
The second shown in the poolhall has some strange distortion, an irregularity that I believe mostly is caused by the lens turbo. The pic of my friend I was playing pool with, taken with the 1.4/50 gave me hope though, and the focal reducer must have provided, if I understand this right, a gain in speed!! - which, of course, simply is marvelous
Today I was very, very happy to see how well it works for portraits with the 1.4/50!!
- even with the 20mm, for portraits the lens turbo should do well, hopefully with pretty much any focal length
Curious how the Mir with the lens turbo would compare I also carried my GXR M with f4.5/15 Heliar, both shot @f8, neither sharpened nor treated for CA
4.5/15 Heliar on GXR M
Mir47K + lens turbo on NEX5N
near center 100% crops
4.5/15 Heliar on GXR M
Mir47K + lens turbo on NEX5N
near corner 100% crops
4.5/15 Heliar on GXR M
Mir47K + lens turbo on NEX5N
yes, the corner is quite bad, the lens turbo won't be the tool if corner sharpness is required.
the far corner 100% crop of the other pic with the kids at the playground looks better

thank's Hari, I was surprised how well they turned out!
and I think that you are right about the haziness, I believe it well may have been caused by the lens turbo not handling direct lights very well. _________________ my photos on flickr: https://www.flickr.com/photos/kuuan/collections |

thank's Suat and Pancolart!
Suat your samples look very good!
Pancolart Saigon has this 'vintage flare' of the 60s, and the "Paris theme" wallpaper may add to that cinematic look too
new lens added: today I tried out a Super Takumar f1.9/85mm ( stacked via M42>K adapter on the PK lens turbo )
I tried to do 'real' shots rather than just test shots, today's however really are just test pics. ( again the pic with the 100% crop has no sharpening, no editing to treat CA. The total pic however has been sharpened after resize = that also is true for the full frame pics in my original post )
the corner of the wide open shot:
100% corner crop @f8
observation: corners look much better than with the Mir, looks like the lens was more responsible for those than the lens turbo
wide open ( sharpened after size reduce )
100% crop ( like all 100% crop no sharpening )

How heavy is the Lens turbo + Nex + 50/85mm combination? 50mm lenses are perfect for the NEX because of their size, but I found that longer lenses are not really good for hand holding due to the added weight.

hm..what should I say..first because I hardly have experience with the lens turbo yet and secondly because this must be very personal:
On one side I never have had problems with the weight or length of any lens on my NEX. This must be partly because I hardly ever have used lenses longer than normal lenses, and if it was e.g. a small and tiny 3.5/100 Pen-F lens, and partly because if I ever did use a bigger and longer lens I let the lens and camera rest on the palm of my left hand. Doing so I never felt that a 85mm or 135mm Takumar to feel more awkward on my NEX than on my ( should add: rel. small and light ) dSLR.
On the other side for me a NEX decidedly best is used with rangefinder ( or halfframe, e.g. Pen-F lenses ), that is lenses that only require a small adapter, usually are also smaller themselves and make for a small, light and well balanced package.
That said the lens turbo is much heavier than I had expected and does add weight that can be felt! It is shorter than a ,normal' adapter though making the whole package more compact and that I like. _________________ my photos on flickr: https://www.flickr.com/photos/kuuan/collections |

Hoan when I bought mine the cheapest 'buy now' had been 189 usd free shipping and seller Lengrin was the only one that had accepted 'best offer'. However the one shown by Lengrin, unlike those offered by other sellers, had not "Zhongyi" written on it's body. I was wondering if there already was another producer, asked the seller if it was a Zhongyi and offered 170 usd. Reply was that yes, it is a Zhongyi, the 170 usd were accepted, the lens turbo that arrived has Zhonyi written on it.
So it was a bit of a gamble and I see that by now cheapest offers are 161 or best offer + free shipping, offer of 150 usd should do. _________________ my photos on flickr: https://www.flickr.com/photos/kuuan/collections |

Thanks for the answer! NEX is "nose heavy" with most SLR lenses anyway, must be better with RF glass. _________________ Latest post on my blog (no new posts):

I agree with this. I tried other lenses too on it. best so far is My CZ vario sonnar 80-200/4 T* on lens turbo, corners is much better than my Schneider Curtagon 35/2,8 wihich looks like real crap with this adapter. (Curtagon is best for APSC)
So, my opinion, If the lens great at Fullframe, then it will be great at lens turbo. _________________ nex5, Olympus EPM1, yashica half 14, Canon eos 650 want to see samples of mine? please click My lenses

that's for sure, some of the disappointment of corner performance of focal reducers certainly must be due to some users knowing their lenses on APS-C only.
just took pics of the combinations used, here they are:
( taken with Macro Takumar 4/50 on Ricoh GXR M )
Mir47K 2.5/20 + lens turbo on NEX5N
Pentax K 2.8/24 + lens turbo on NEX5N
Pentax M 1.4/50 + lens turbo on NEX5N
Super Takumar 1.9/85 + M42>PK + PK lens turbo on NEX5N

interesting Calvin!
could you please be so kind and explain to me what is meant by 'flat field lenses'?
from the little experience with the lens turbo I'd say best benefits are:
- gives extra speed, great for low light
- approximates angles and dof the lenses have on FF, this adds new possibilities specially with normal and wide lenses, offering more shallow dof resp. subject separation at wider angels when corner sharpness is not required.
biggest downsides:
- corner performance, it's not useful for landscape and architecture, though I read that some lenses stopped down enough may do fine.
- it adds it's own 'signature', 'changing' or 'diluting' the lens's characteristic.
a focal reducer sure is a teaser to get the real thing, a FF
btw. I should mention that the last photo I showed in this thread had not been taken by me, but by a befriended photographer while playing with my camera / lens

Since last friday I also have a PK lens turbo and I enjoy using it very much.
- Kuuan, I can confirm everything you said about it.
So far my favorite lens on the lens turbo is my Leitz Summicron - R 2/90, this massive pile of glas delivers wonderful portrait images.
Without having done serious testing I suggest that not all lenses perform equal well on the lens turbo.
Kuuan, can you tell us something about the performance the Pentax M 1,4/50 delivers on the lens turbo?
Unfortunately I was not able to mount my favorite 35mm lenses, the Flektogon 2,4/35 and the Primagon 4,5/35 because my M42-PK adapter does not fit into the lens turbo.
Has someone already tried the pentax 3,5/35 on the lens turbo?
