Enlarging lens question
"David Nebenzahl" wrote in message .com... Richard Knoppow spake thus: ... Kodak Enlarging Ektars are also excellent and often cheap used because they are so old. We may have been over this before, but what do you think of the predecessors to those lenses, the Projection Anastigmats? (Apart from their not being coated.) I've got a bunch of these (cheap from eBay) that I've gotten excellent results from. I've not had one to test. They are probably good performers. The Enlarging Ektar series was intended for color work, they are well corrected for lateral color. The 50mm and 75mm are Heliar types (5 elements in 3 groups), the 152mm is a dialyte (four air spaced elements). I have a 75mm Enlarging Ektar, which holds it own compared to an older Componon. I also have a 152mm Ektar but its scratched up. The lenses I use for enlarging are all Componon-S except for the 80mm one which is an earlier chrome barrel one. -- --- Richard Knoppow Los Angeles, CA, USA |

It's a 161/4.5. Very heavy for such a compact lens. The outer dimater of the threaded area is 50.8mm and the front is 49.1mm. In looking at the specular reflections of my rooms overhead ligt in the lens, there are 5 reflections that are easily observable. I picked mine up on Ebay for the princely sum of $7.50 +S&H but I don't feel cheated as the lens came in the original box with the original packing paper and lens cap. I'd say it's in mint condition and never been used. == John S. Douglas Photographer & Webmaster www.legacy-photo,com www.xs750.net |

And it makes very good prints from 4x5, that I can vouch for. -- Save the Planet Kill Yourself - motto of the Church of Euthanasia (http://www.churchofeuthanasia.org/) |

Enlarging lens question
That's the best advice I've rad on this thread so far!
"Nicholas O. Lindan" wrote in message link.net... "Colyn" wrote needed another lens for an Omega C700 I found which will go to a friends son who is learning to process and print his own photos. [Found an el-Omegaron and el-Beselar...] I had a Nikon 50/3.5 Tessar formula lens which I replaced with a 50/2.8 6-Element. The difference in prints was startling: I couldn't tell the difference. Several hundred dollars down the drain. I have very good acuity, I spot my prints with a 30x stereo microscope, I have 'blads, Leicas and Sinars all with SOTA lenses and my requirements for 'sharp' are higher than any other anal retentive I know. Bottom line: IMO there is more hype about lenses than there is about developers - that doesn't mean there aren't some really awful lenses out there but Apo-Costalotagons don't improve anyone's photographs. Put the lenses on your enlarger and make a few test prints. Only you can say what is acceptable you. I wouldn't spend money on lenses for the kid when he may not get hooked by darkroom work. As a first lens either of these is great. Play 'Princess and the Pea': if the kid complains about sharpness then you know he is on the hook. -- Nicholas O.
