The first part of the Lens Rentals write up wasn't overly helpful but they've added a second part where they take the lens apart to look at what's inside.

Generally they were pleased with the build quality and materials.  The plastic tabs are, apparently, plastic sheaths over metal tabs inside.  They could still break but if they're made of the high quality plastic other parts of the lens are then it shouldn't be a huge concern.

I would say that with the sensors getting better en better it is obviously the lens is bound to be a one trick pony looking at pixel level..
In the case of this samyangTS lens - I think it is a good thing if they designed it to perform perfectly at f8 and f11..
flat field ( not sure) - really sharp corner to corner even shifted...good coatings...  would already be a very beautiful outcome...
After all you buy a 24mm MF lens in a way for only 1000

Ephotozine has posted their review of this lens.  Their resolution figures seem to be out of step with some of the others.  Given the possible issues with focusing I saw in one of the other reviews in this thread, I think I'd put more stock in the ephotozine results.  It may also point to manufacturing QC issues.

Not familiar with the Lenstips site so don't know how reliable it is.  If you can get past the hackneyed English, their results seem more in line with ephotozine than The Digital Picture.

EDIT:  Sorry, forgot that the ephotozine review has already been posted.

from this review i want to quote this:  ... for this review, the lens was tested on a Nikon D700 using Imatest..."

So excellent results on a 12 MP body...
Also you really have to do some very delicate testing for the differences are in the details among these 3 shift lenses   (nikon, Canon. samyang)
is all about field curvature etc etc... A simple Imatest result is not enough to rely on.

Yes, I know they used a D700.  The Digital Picture used, I believe, a 1Ds MkIII.  An additional 9 MP isn't much and shouldn't account for the significant differences in image quality results. 

As I noted, the results from the Lenstip site are more consistent with ephotozine than TDP and they also used a 1Ds MkIII.  They also tested the lens shifted.

Unless TDP got a bad sample, I don't think this lens is as bad as they make it out to be.

Has anyone done the more 'delicate' testing you mention?

I would think a real test would be on a D800E between the Nikon and the Samyang.

People on Dyxum report that on Sony A850/900 pentaprism blocks vertical rise around 9,5mm (of 12). Pity.

Good results.  He didn't seem concerned that the knobs and tabs were going to break imminently.

Yesterday i bought Samyang 24mm Tilt-Shift F3.5 lens.
It's only option of wide-angle TS lens for Minolta|Sony A Mount (except cosmic-pricey 28mm SK).
Immediately i've discovered that i cannot use shift-RISE function more than 9.5mm (of total 12mm) because lens base barrel touching a pentaprism housing of my Sony Alpha a900 (the same will be at least with a700 and 850). Do they ever ever test this lens on this cameras?  Because User Manual shows only operation with oldish aps-c alpha 350.
Second discover is not so camera-specific: you forgot or miss or mis-design a counter-clockwise rotation. I CANNOT use diagonal shift movement fully. Not only because of Pentaprism.
I only can SHIFT top right corner OR lower left.
I have to rotate my camera and mount my tripod on the ceiling to proper use of DIAGONAL shift?
I think this is major fault, more significant than wide-open sharpness.

Sorry but the fault is with the camera body not your new lens.

Look at nikons PCe 24mm it has the same problem with the d800.

Nikon D800 has onboard flash.
Nikkor PC 24mm has proper shift rotation.

Arax 35mm is not so good.
Much better is separate T|S adapter and 35-40mm Medium Format lens.
Pentacaon Six| Kiev mout has very good 55mm shift lens (under Mir or Arax name).

Hi,

I have not tested the Arax 35. I have some experience with Arax tilt adapters, they work as advertised but have problems with flare. Just fine in studio/lab but not so good in real world.

I would consider Mirex adapters as they have a different construction.

Best regards
Erik
