  1. I would not attempt an amateur effort to fix a Rolleiflex, even if you had a service manual. I'm not sure which model Rolleiflex you have, but ask Oceanside Camera Repair, Manhattan Beach, California (AKA Harry Fleenor) if they service your model. Oceanside repaired my 2.8C.
  2. Thanks for discussing the FL interpretation further. I agree the FL is 1000mm and is unchanging when switching formats, In this scenario, the D700 body is simply cropping. Below are two images made with the setup Hasselblad 500/8 CF + 2X Mutar on D700; both made at ISO 400. These JPEGs are generated from unprocessed NEFs.

     

    Bird was positioned at about 6m. Moon focus was checked with "Live View". I think the images are good and reasonably sharp.

  3. Thank you for your valued perspectives. The D700 sensing the center portion of the 6x6 image would give the 'impression' of a longer FL than 1000mm pictured lens setup. The estimated "apparent" 1600mm FOV generated by the D700 is reasonable. I don't have a 1600mm f/16 telephoto lens for 35mm film camera. Leveraging the good quality Hasselblad V optics I have on hand is a viable option for the few times I may need that reach by using the FX DSLR. Admittedly, I can crop the 6x6 scanned film image to get the same, but the D700 image is available faster and cheaper.
  4. Purchased used Leica M2 button rewind (BGN) - most obtainable Leica to me. Most importantly, I listened to 1s, 2s shutter speed accuracy, clarity of 35-50-90 framelines and focus patch, film advance smoothness and shutter curtain condition. The body had slight dents, leather was intact although not original; overall acceptable cosmetically and complete. Can't be mint obsessed when buying BGN. With functional criteria being met, the pictures with 2/35 ASPH were predictably outstanding. RF alignment is something that could only be checked out with 2.8/90 Elmarit-M. With sharp pictures at 2.8, I was lucky there. Solid, small, and agile camera, the M2.

  5. The 18mm f/3.5 is one of my favorites. It makes the lowest edge distortion I have ever seen. It uses standard front filters, offering plenty of imaging options. The next wider lens is the 15mm, but it's big, flares more, not as sharp, and offers limited filtering options, in comparison.
  6. Tilt-shift lenses (for 35mm cameras) will help you obtain tremendous Depth Of Field without closing down the lens aperture too much, avoiding image degradation from diffraction. This effect is based on the Sheimpflug principle, which view camera users easily exploit.
  7. To clean the lens, use compressed air, then soft brush, then microfiber cleaning cloth moistened with lens cleaner. Rear lens scratches are worse than equivalent front lens defects. Any rear lens defect will be clearly visible when shooting towards the light at small apertures. Point a bright flashlight in the lens and observe resulting image formed on a white piece of paper. If dark fuzzy spots or lines are seen, the lens is degraded.

  8. There is no newer version of the Nikkor 20-35mm f/2.8D. The new available zooms are wider, in response to market demands. Go to the Nikon site and explore what's on offer. Nikon now provide MTF charts, but they don't tell you everything about zoom lens performance. Nikon have their secrets.
  9. Yes, FLE=floating lens elements. Zeiss 40mm CF T* FLE lens is compatible with 500 series V cameras. As Q.G. attested, the FLE lens is better than the older C (non-FLE), and more desirable, IMO. Below is an unretouched example film image taken with 500CM and 40mm CF T* FLE on Ilford Delta 400, illustrating the lens' abilities. Please excuse my head's shadow. Very low distortion, excellent sharpness and contrast are evident. This is the imaging performance one expects from the lens you seek.

  10. Imagine 40mm lens offering about 20% more scene, vertically and horizontally, compared to your 50mm. How often would you confront situations where a 40mm lens will improve your photo over one taken with your 50mm?
  11. Assuming you seek CF T* model, consider that they sold for $4000 new in 2004. In today's digital world, figure $2000 LN, or $1400 EX, if you want nice. I bought bargain, with light coating scratches on the front glass; no issues - just great pictures.
