dear all,
beware of the new Schneider 28mmXL Digitar on the IQ180.
It got uncontrollable color cast EVEN WITHOUT SHIFT!
A fellow getDPI forum member Chris Hauser and myself met in Hong Kong last weekend and had a fun shoot out comparing the Schneider 28XL and 43XL with the Rodenstock 32HR-W and 40HR-W. He was on an Arca with the Rodies and myself on an Alpa with the Schneider both equipped with IQ180s.
to simplify our findings I simply grouped those images and made screen shots. The lens and shift amount can be found below the respective images.
The lens test were as follows:
- 32HR shifted up: 0, 5, 10 , 15 mm plus corresponding LCCs
- 28XL shifted up: 0, 5, 10 , 15 mm plus corresponding LCCs
- 32HR shifted left: 5, 10 , 15 mm plus corresponding LCCs
- 28XL shifted left: 5, 10 , 15 mm plus corresponding LCCs
Please note while both the Arca and the Alpa allowed for more than 15 mm upward shift the 28XL due to its proximity to the sensor pane can't be shifted higher than 15mm on the Alpa. The 32HR peaked at about 19mm when we reached the image circle of that lens.
Also the camera were right next to each other and there we minimal light changes during the 15 minutes of shooting these test.
I deliberately did NOT make any changes to the LCC or the image itself (no adjustments, straight out the camera).
All were shot with the same IQ180 on f11 1/8sec (1/4 for LCC) and WB set to Daylight.
Despite the lack of any scientific procedure I think the images speak a clear message:
the 28 Digitar as great as it is on other backs is NOT recommended on the IQ. I had to buy the bullet and sold it right away.
On another note: thanks to Jack and Guy for this forum plus everybody's else's accumulated wealth of information & not to mention the fact that you bring folks together as well.
Especially in this part of the world (China) its hard to initiate a shoot out with such rare equipment specs.
Special thanks also to Christopher for making me loose a few thousand bucks this weekend on the trade in
Hope some of you can avoid this costly mistake.
