I use SL2000F since about 1992 until recently switched to Contax C/Y. I also own SL35, SL35E, SL35ME, 3003.
I have a few points to raise:
1. Are the lenses of QBM I to QBM IV usable on SLRs from SL35 to 3003? Are their differences analogous to that between MM and AE lenses of Contax RTS series?

I am not sure what is QBM I to IV. I only know 3 types of QBM:
1-pin type: no aperture info to camera body. Therefore stop down metering for all models. However most convenient to use with SL35 where the camera is designed to work using stop down metering. Should come with a manual/auto aperture switch.
2-pin type: auto aperture (same as 1-pin) and with aperture info transfer to body. Thus work with open aperture metering for all models except SL35. However, this version when use with SL2000F, 3001 and 3003 there is no aperture indication in the view finder.
3-pin type: the latest series, usable on all bodies and with aperture indication for SL2000F, 3001 and 3003.

2. (Personally speaking) The main attraction of this series is Carl Zeiss lenses, with their characteristic triangular aperture blades. Most interestingly, it contains some of the designs which were only made by Carl Zeiss in Germany for this line of SLR, the D35 f2.8 lens being one prominent example.
Many of the QBM designs are different from the C/Y one. 50/1.8, 50/1.4, 35/2.8, 85/2.8, 135/2.8, 135/4(not available for C/Y), 200/4. 35/1.4 I am not sure as C/Y has a aspherical but not mentioned in Rollei catalogue.

3. There are various discussions about the different colour renditions between Contax and Rollei lenses which are attributable between HFT and T (star) coatings. Does that claim hold true for those Rollei lenses made in Germany? I guess not because actually they are T coated as well. The difference is due mainly to difference in year of production, which points to a (slight?) different/advance in the T coating technology, just like its Contax counterpart??
I but lenses to take photo all the time and very very seldom like to compare detail charateristics. I can only say I like the overall presentation of Zeiss optics, QBM or C/Y alike. However, Rollei HFT has a very nice reddish/brownish look which I like very very much compared to the boring C/Y T* coating but in terms of look only! However, comparing the coating of 16/2.8 and 18/4 both mounts look alike for these 2.

4. The functionality of the 3003 is state of the art at the time when it was released in 1984(?). Does it suffer from the problem unreliability of other Rolleis?
IMHO 3003 in many expects is still state of the art. Even to date still the only SLR with:
Just take the film magazine and battery apart u will realise how small the body is, compared to Canon F1 with winder and Nikon F3 with winder at the same era.
As usual, electronic Rolleiflexs are not perfectly reliable, but I do not have any problems with those I used extensively. By the time 3003 was launched should be quite stable already as SL2000F was the first generation of these wonderful 35mm Rolleiflex.
Hope my info helps.
