Hi..Is there a difference in optical quality between mint Rolleiflex 3.5F cameras ranging from type 3 early 60's and type 5 early 70's.
Glad of any advice, many thanks.

I recall reading that the later cameras had a 6 rather than 5 element planar lens. To what extent this might have affected the optical quality however I know not.

Thanks. That numbering means mine has 6 elements.
And if the additional element was actually a warm-up filter it would also explain why the camera gives distinctly (er) warmer results than an earlier version I once had...

I think warmer just means warmer. I've owned a couple of the Rolleiflex cameras w/ Planars, both early and late, as well as a 2.8 Xenotar. They all were, w/o a doubt, the best lenses I ever shot in medium format, excepting the Heliars on Voigtlander folders. The Heliars aren't necessarily better, they just image w/ more of a 3-D look.
Type 3 was the transitional version. After 2753002 the Planar had six elements. After 2299547 the Xenatar had six elements.

Thanks for posting that! I've seen it before at some point but couldn't recall the precise details.No, the six element Planar and Xenotar have no warming filters. They were new designs, with one element split in two and the flat surfaces cemented together. It's said that this was done to simplify the production, and that the quality was the same as the earlier five element versions.

Dear Patric,
Thank you for your inquiry to Carl Zeiss.
Well, the reason for the change of the lens design was an improve of the lens performance (less vignetting, more consistent performance across the image field) as well as an easier production. The splitting of the second lens element into two cemented elements with a plain surface in between is easier in production than the meniscus element.
Hoping to be of service to you we kindly ask you to contact us again should you need further assistance.
Sincerely,
