Digital ICE and No digital ICE samples
The image below was scanned with an Epson 4490 scanner without to use Digital ICE technology, the second one had identical scanning process but using Digital ICE technology, the original is a 6x6 Agfa RSXII 50 slide taken with a Rolleiflex 2.8C Xenotar, there is no visible difference about sharpness for both images(please click on thumbnails).

Rollei TLR cameras weight
I weighed these cameras with an electronic precision scales originally, the cameras weight is the same using this kitchen scales except for the Rolleiflex 3.5F, it looks some grams heavier because it was loaded with film, the original measurement without film was 1140 g and now due to the film is about 1170g; the 2.8C weight for both measurement without film was 1200g and the Rolleicord IV without film for both measurement is 850g. The kitchen scales used below is pretty exact according the electronic scales, with divisions each 20g and more significant is the fact the cameras were weighed using the same scales. Please click on thumbnails to see details.
The first one below is the 2.8C Xenotar 2.8/80, afterwards the 3.5F Planar 3.5/75 and the third is the Rolleicord IV Xenar 3.5/75.

Roller reflection issue
Black rollers: The new Rolleiflex FX uses black rollers, please click on thumbnail.

This is another example about no roller reflection, taken with a Rolleiflex 2.8C Xenotar 2.8/80, Agfa Scala like negative developed in Rodinal 1+25, please read comments below about this issue.(click on thumbnail for full size image, copyright cmfreaza)

These two B&W photos taken in sequence as you can see according the numbers are another example about no roller reflection, this time with the 3.5F, Planar 2.8/80, Kodak T max 400, Rodinal 1+25. The frame number 10 is again a strong backlight, a direct shot to the sun, and the frame number 11 don't show reflections like for the color example (see note and photos below), please click on the thumbnail for a full size image.-

Some old Rolleiflex and Rolleicord TLR users have commented that a roller reflection appears at the bottom of the next frame if the the previous frame have received a strong light exposure on the upper part, f.e. a direct shot on the sun; I have seen some examples and it's a real problem when it happens, however I never knew about it til last year and I never had this problem with my Rolleiflexes and Rolleicord cameras, you can see below an example about no roller reflection with two slides taken in sequence with my Rolleiflex 2.8C Xenotar 2.8/80 and Fuji Provia 100F film in the same conditions described above, the first frame with the strong backlight is a direct shot to the sun taken during our subtropical summer and it's difficult to imagine a worse situation for a roller reflection, but the 2.8C separated both frames perfectly as you can see; BTW the images are inverted in the camera (click on the thumbnail for full size image, ©cmfreaza).-
