    Thanks. That's what I thought.

    Canon EF 85/1.8. Very sharp!

    NEX-6, Speed Booster, Canon EF 85/1.8, Effective f/1.3

    This lens also vignettes wide open on a FF Canon.

    Finally, I also tried a Canon lens that will auto focus with the Speed Booster on a NEX- the EF 40/2.8 STM lens. It hunts and at times gets the focus right. Since this lens is not that tiny to be a "pancake" for me, I will pass. It appears to be quite decent though, optically.

    Hi K-H, This might sound odd but the dprevs forum format makes it really unreadable for me. I look at something specific when pointed to a particular post like you did. I thank you for that.

    One snap with the Olympus OM Macro 50/3.5.

    This lens, practically, was a give away (US $10/-).

    Re: Speed booster for NEX

    Here is an extreme case with an esoteric lens.


    Untitled by Vivek Iyer, on Flickr
    NEX-6, Speed Booster, UV-Nikkor 105/4.5, Effective f/3.2, 1/2X magnification.

    At this magnification, the lens basically doubles its size- meaning the exit pupil is too far away from the Speed Booster's optics.

    This perhaps is similar to K-H's test shots with the Telyts.

    Although, I am sure that if I just remove the lens head and use it with a larger diameter focus tube, the vignette/darkening will go away. FWIW, UV-Nikkor 105/4.5 covers 6x9 at infinity and at f/4.5 without its helicoid.

    A couple of wide open shots with a DX (APS-C only) lens, the Sigma 30/1.4.

    at its closest focus distance.

    I shot a wall to check the corners without realising that a light was behind me.

    Interesting, that Sigma DX covers more of the sensor than I would have thought.

    Re: Speed booster for NEX

    Hi K-H,

    I noticed in that post there is a lot of talk of the magenta corners and was wondering if anyone had tried turning off the the settings:

    Menu -> Setup -> Lens Comp.: Shading
    Menu -> Setup -> Lens Comp.: Chromatic aberration

    I assume these settings are for jpeg but there is nothing to say they are. They are set to auto by default on my NEX-7. I would test it but I don't have any that create the magenta corners and I have firmware 1.01

    Of course, khaw that's me.

    Best, K-H.

    Vivek, thanks for the how to re "trimming" the tabs.

    You know, Peller Estates is just up the road from me. They have a nice restaurant and the wine isn't bad.

    I was surprised since on a Nikon D300, the corners were always iffy, wide open.
    This lens will make an ultrafast "normal" for the m4/3rds if one can put up with its bulk (67mm filter thread).

    Also, mounting in the Speed Booster is not an easy affair. Though it does not affect the optics, mechanically it is too tight of a fit. It needs a bit of force to dismount.

    I have not tasted the "ice wine" yet. Years ago, BC (Kelowna) wines were always considered as one step lower than any Ciders. This might have improved now. Well, they can't make it worse. I did not know that Ontario produced any wine, until recently.

    Re: Speed booster for NEX

    A couple of lenses (Nikon F mount) that do spectacularly with the SB on a NEX are the Nikkor 20/3.5 AiS and the Vivitar Series 1 90/2.5. I will post some samples later.

    I also briefly checked the PC Nikkor 28/3.5. Full shift in any orientation is no problem at infinity. With full shift (from normal), the speed drops by ~1 stop-not unexpected.

    Whoa there, Bessie. The Canadian government sends attack beavers after people who make comments like that. If you see a large rodent on the street, better run.

    I'm very curious to see your results with the Vivitar 90/2.5. I've got the prescription for the this lens, and on-paper it does extremely well with the SB except in the extreme corner. The Vivitar 90-180/4.5 should work better in the corners because its exit puil distance is reasonably short, and it doesn't change during zooming or focusing.

    Hi Brian,

    Here is a snap. Weather was not great today. Cold and rainy.


    Untitled by Vivek Iyer, on Flickr
    NEX-6, Speed Booster, Vivitar Series 1, 90/2.5, Effective f/1.75.

    I own two samples of this lens and at the moment only one is visible to me. Absolutely no vignette worries from infinity to 1:2. I am yet to try it with the 1:1 adapter.

    Those who have used this lens know that it suffers from (internal?) flare problems and reduced contrast. While the flare problem still exists, the contrast gets boosted but to a very pleasant degree. Combine that with its high res nature at pretty much any aperture, it is simply awesome! Bokeh is smooth. This lens alone + the SB is worth every cent! If I sound a bit too generous in my descriptions, I am really not.

    I also happen to have the Vivitar S 1 90-180/4.5 Flat Field Zoom. Located it. Will check it out soon.

    A sample from the 20/3.5 AiS Nikkor.

    I shot a bunch with this combo. Suffice to say that this will replace a few C-V wide lenses for street photography for me. Totally useful and impressive performance.

    Quick report. After seeing the Summicron R50 adapted I tried with the Elmarit R 35. No joy. Once the shroud is gone, the convex rear lens surface conflicts. Furthest focus is about 20'.

    Re: Speed booster for NEX

    If you would bear with me for the subject, WB and even the focus, here is a bunch of tests..

    The first show the Vivitar S1 90/2.5 at 1:2 without the 1:1 adapter.


    Untitled by Vivek Iyer, on Flickr

    This is the result when using the 1:1 adapter and at 1X mag.


    Untitled by Vivek Iyer, on Flickr

    With the 1:1 adapter if the magnification is close to 1:2 then images like the first are obtained. As it gets closer to 1X, the corner darkening intensifies.

    Re: Speed booster for NEX

    A correction: The Micronikkor P 55/3.5 A mounts just fine without any problem, though the rear baffle looks menacingly close.

    The Nikkor 35/.14 looks delicious. There seems to be no corner worries. I do not think I have a great sample. It is an old Nikon A version and has an yellow cast (had this on film). If someone has a modern AiS version, it is definitely something to use, althoug it may not be possible to use a hood.

    Vivek,
    Thanks for all this! I see images of the nikkor 20mm 3.5 ais with a few smallish things on the back. Did you need to cut or file anything to use this lens with the SB?

    Re: Speed booster for NEX

    Hi John, My sample is still "mint". No mods, none whatsoever!

    I also want to add a correction here-

    To be safe, i trimmed about 1mm of the rear shroud on my GN-Nikkor Auto 45/2.8. It is entirely worth the bother to use this lens with the Speed Booster!

    This is a tiny Tessar clone which is a mechanical master piece! Apart from the nifty GN mechanism, it has a well rounded aperture diaphram. Simply fabulous!

    If anyone locates the hood (I believe HN32), please drop me a line.

    I finally got my EOS-F Adapter and have uploaded a sample with my Zeiss Planar T 50/1.4 at a boosted f/1. Focus at infinity works on the lens with the speed booster. Now wish my c/y adapter would arrive.

    lovely!

    i tried the Planar 50/1.4 and the EF 50/1.4, last Sunday. Very big difference in terms of OOF renderings. Zeiss Planar is "perfect".

    Re: Speed booster for NEX

    I will just report on two low grade Nikon zooms.

    The 18-55 AFS ("kitzoom for APS-C cameras")- from 24mm to 55mm no vignette worries, wide open. At 18mm there are prominent dark corners.

    The 70-300 f/4-5.6 AF-D- Works fine at all FLs, wide open.

    That is a battery of lenses on the table behind the one you were shooting.

    Much more testing. Great

    I'm really learning a lot from your tests images, Vivek - thanks so much for doing all this!

    I have to confess that an 85/2 is not something I would have though of as a compelling companion to the Speed Booster since it winds up being almost the same (at least superficially) as a plain vanilla 50mm f/1.4. However, the bokeh in your shots looks really nice. I'm curious about your opinion regarding the 85/2 + SB vs. a plain 50/1.4.

    I'll have to dig out my old 85/2 Nikkor to see if it gives similar results.

    Re: Speed booster for NEX

    Bear in mind the 85/2 will be essentially an 85/2 when adapted with the Speed Booster (~1.4 in light gathering but ~2.0 in DOF equivalency.)

    If you are talking about a straight adaption of a 50/1.4 to a NEX, then yes, you'll be at roughly 75/1.4 in light gathering, f/2 in DOF equivalency.

    I hope that post is NOT for Brian, Robert. Brianc1959 is the creator of the Speed Booster.

    I have to confess that an 85/2 is not something I would have though of as a compelling companion to the Speed Booster since it winds up being almost the same (at least superficially) as a plain vanilla 50mm f/1.4. However, the bokeh in your shots looks really nice. I'm curious about your opinion regarding the 85/2 + SB vs. a plain 50/1.4.

    I'll have to dig out my old 85/2 Nikkor to see if it gives similar results.
    Hi Brian, I am the one to be thanking youfor this!

    I will try a comparison of the 50/1.4. However, I am sure that this OM 85/2 is something special.

    FWIW, I bought this sample from monza (Robert).

    Nice test pictures Vivek! The 85/2 definitely looks great.

    Here are a couple more from this weekend w/the Macro-Elmarit 60.

    The three lenses I can't wait to try are C/Y 60/2.8 Makro Planar, 50/1.4 Planar, and 85/2.8 Sonnar.

    Hi:
    I'm Brian. Pleased to meet you!

    I'm a bit old-school, so I never think in terms of equivalency with regard to focal length and f/#. So the combination of an 85/2 plus the Speed Booster *is* a 60mm f/1.4 lens.

    So, I'm thinking that superficially it should act pretty much like an ordinary 50/1.4 mounted to a NEX with a plain adapter. What I'm interested in here is whether there is something subtle (and hopefully worthwhile!) going on with a bokeh difference between these two cases. It's just something that hadn't occurred to me until I read Vivek's post.

    Re: Speed booster for NEX

    Every day I like coming in here and getting to see Vivek's great shots on a wide array of lenses. Now Taylor's added some more great shots and to top it off Brian is adding his thoughts. I have been telling everyone about the speed booster and think it is a fantastic idea.

    Nice Taylor. I have been looking at your images from the SB + 60 Macro combo.
    Very nice skin tones in the street musician shot.

    FWIW, the short macros (pretty much from any maker) of 50-60mm FL are usually optimized for a magnification of 1/10X and the longer ones- 90-105 FL range for 1/5X. This applies to unit focusing lenses and does not hold true for floating elements design.

    An Infrared snap.

    Hacked NEX-C3, Speed Booster, Olympus OM 85 f/2, Effective f/2, ISO200, 1/160s, Hoya R72, Infrared capture

    It is very difficult focus wide open in IR as the DOF scales are even narrower in IR. So, I had to stop down one stop.

    The Speed Booster has no ill effects (hot spots and such) in the near IR region.

    I also briefly checked the PC Nikkor 28/3.5. Full shift in any orientation is no problem at infinity. With full shift (from normal), the speed drops by ~1 stop-not unexpected.

The Vivitar 90-180/4.5 should work better in the corners because its exit puil distance is reasonably short, and it doesn't change during zooming or focusing.

    ... and I for one am very curious to see your results with the Nikon PC-Nikkor 28mm f/3.5 especially since I have one put up for sale at the B&S board at the moment

    oo ooo, I see a f1.4 penf lens there, is that the 40mm f1.4? I have one, and it is a joy to use.

    All these amazing speed booster shots, is really making me super envious and the desire to get one gets stronger, just need to save up more $$$. Also I want the adapter to use phase AF on sensor for the likes of nex6 and nex5r.

    Re: Speed booster for NEX

    Every time I mount a lens via the Speed Booster and make pictures that becomes the new favorite of mine. I am going to have a very difficult time to even decide on a "standard" 50 to use. Today I had the Summicron R 50/2 ( and an Olympus OM85/2 and a Vivitar S1 90/2.5) to shoot the Chinese new year festivities in the Hague. I have uploaded a big bunch of photos here:

    Speed Booster - a set on Flickr

    I will probably post a few later.

    Oh, the SB is simply awesome!

    One other interesting factoid- the NEX-6 lasted for >460 shots on a single charge! All manual lenses. No review. Only RAW captures.

    Re: Speed booster for NEX

    Hi Vivek,

    Congratulations for all your lenses that work well with the MSB.
    Thanks for sharing your tremendous work.

    I finally got a Leica Vario-Elmarit-R 1:2.8-4.5/28-90 ASPH.

    My first test images with a regular adapter are here:
    Re: Metabones Speed Booster - Vignetting with Tele-Lenses: Sony NEX Talk Forum: Digital Photography Review

    With the MSB are here:
    Re: Metabones Speed Booster - Vignetting with Tele-Lenses: Sony NEX Talk Forum: Digital Photography Review

    One really has to look at the included full resolution images to see what's going on.

    One thing I noticed with that lens and a regular adapter on the NEX-7 is that I can focus with 90 mm, change focal length to 28 mm, and the lens is still in focus.

    However, with the MSB focus dramatically changes as I go from 90 to 70 to 50 to 35 and finally to 28 mm. In order to focus for 28 mm focal length, the distance scale on the lens is completely off.

    Vivek, have you noticed a similar behavior with any of your zoom lenses? Thanks.

    With best regards, K-H.

    Re: Speed booster for NEX

    K-H, I am at a loss to understand how such a joyful experience for me is not the case with you.

    These are the zooms I have tried:

    1. Canon EF 28-80 f/3.5-5.6 IV
    2. Vivitar Flat Field zoom 90-180 f/4.5
    3. Nikkor (AiS) 35-70 f/3.5
    4. Nikkor (AiS E series) 75-150 f/3.5
    5. Leica 75-200 f/4.5

    None of them show any corner softening problems at all. It is remarkable that barring the Vivitar zoom, none are unique. All behave well.

    I also tried a Hoya 80-200 zoom (OM mount) I had with one of my OM bodies (I had never used it before though!) that was down right horrible with weird distortions. I am pretty sure it is down right horrible on its own.


    What is the FW number in your NEX-7?

    Re: Speed booster for NEX

    Thanks Vivek.

    We really have two different adapters though, in all fairness.
    Before the last test I updated the NEX-7 Firmware to Version 1.02.

    With best regards, K-H.

    Re: Speed booster for NEX

    Hi K-H,

    I just looked at this: http://en.leica-camera.com/assets/fi...=file_1848.pdf

    From a fleeting glance of that, it occurs to me that I would have very different results from50mm (perhaps even earlier) on. If this sounds like a riddle, i can expand on it later for you.

    I highly doubt that we have two different adapters. The optics ought to be identical. I would check if the sample allows for infinity focus. If not there is a solution.

    Please check the white paper and see if the descriptions match your results.

    Also, just look at your sensor with the SB mounted on the camera. How does the sensor look like?

    It is about 3 deg C during day time and evenin the city, after 30 mins, my fingers are frozen. I can not use gloves with a camera. When it warms up a bit (this is a flat/windy country), I will take some infinity/landscape shots. I will even put some zooms to use out of curiosity. It is a pity that I sold my 14-24 f/2.8 Nikon zoom. Although, I am sure that I can borrow one for tests.
