    Looks good.
    Would be hard to justify the Canon and Metabones adapter based on this.

    I think that I'd be wanting to check out some full resolution files before coming to that conclusion. The 24 TS-E II on metabones IV is simply outstanding on the Sony, heck even on my Alpa FPS/IQ back.

    From what I've read though, the RokiBowYang benefits from being stopped down so for pure landscape work where you want a wide focus wedge when tilting the quality may be fine.

    The general nature of these lenses is that they tend to be optically simpler than the more corrected designs from Zeiss/Nikon/Canon etc and hence the extra CA and distortion (but on the flip side I use a Rockinon 14mm & 24mm for stars BECAUSE the design is less corrected and gives me less coma). I've been lucky so far but you need to watch for sample variation with these lenses as there is a fairly reasonable history of decentered lenses - not a problem so long as you are prepared to try a couple and get the best one.

    You certainly can't complain about the price.

    Well there is nothing like practical experience

    From a trip to a village church in Suffolk earlier today, all with the Samyang T-S 24mm and Sony A7RII

    Drop front:




    Rising front (shift), two exposures, combined by hand the old fashioned way to enhance some detail in the stained glass.



    Tilt



    The biggest problem is precision. On a relatively small camera, its harder to align everything than on a ground glass of a LF film camera so errors can and do creep in. Accurate focussing is critical. But its a very good lens. All at F/11.

    A comparison shot between the Samyang and Nikkon tilt shift 24mm lenses. The Samyang is longer due to the built in E mount

    Samyang: 16 elements, 11 groups (2x Aspheric elements) 82 mm filter thread

    Nikon: 13 elements, 10 groups, 3x Aspheric and three ED glass, 77mm filter thread

    The Samyang does have a distance scale for approximating DOF - I just got it the wrong way around...

    Graham I have a 17, 24 and 90. The files are outstanding with a A7RII. Just a question of how close this lens can get in optical performance. At web size it would be hard to justify the Canon or Nikon.
    an 80 inch print would be a different matter.

    Below is a link to a full size image from the Samyang @ F/8, with shift applied.

    This full size image shows the best and worst sides of the Samyang.

    Its been decoded using ACR, with +8 distortion applied and "remove CA" ticked, shadows boosted and highlights pulled back a little, no sharpening applied in Photoshop (ACR defaults).

    Resolution is very good, in my opinion, but there is flare visible top left and bottom right from a strong sun top left just out of shot. I have only seen this a couple of times and had I noticed it at the time, I could have prevented or mitigated it by shielding the sun. Samyang's weakness is clearly their lens coatings are not as good as some.

    Hi Quentin,

    Yes, flare can be quite difficult to deal with when using the Samyang on sunny days and I quite often need to shield the lens using my hands (sort of like dodging in the darkroom) or a wide brim hat. Other than that I have no serious complaints with this lens.
