    Like I said, the original question had nothing to do with astro-photography.

    YOU NAILED IT.

    Just figure out how much ND you have or want.

    Re: Using 8x10 camera as enlarger for 120 film?

    Well, I use my 4x5 enlargers to make prints from Minox film (8x11mm) -- that is a much more extreme situation. Use it or lose it!!

    I have a Minolta MC Rokkor 85mm f1.7, but I think you summed it up perfectly -- it's a toy. Save it to hang on your Christmas tree is 10 months.

    Re: Nd filters versus stopping down

    A ND filter does not change the DOF. It just cuts down the light getting to the film. So how much DOF you want needs to be determined first. At the same time, you need to determine what speed you...

    There's a lot of "brand snobbery", for sure. The same is often said for the Kino-made, Vivitar lenses, as well. Some go ga-ga over the Series 1 lenses which were actually made by several...

    Judging from the serial # on the lens "10000" it was one of nothing. Most early Vivitar lenses used the first (and second) digit to show the manufacturer. For example, 22xxxxx, meant Kino (AKA...

    All of my Fujinon, Schneider, Mamiya, Rodenstock, and Minolta large format lenses are muti-coated, but many of the elements do not look multi-coated to my eye. So a multi-coated (an undefined term)...
  14. Re: Fuji 250 6.3 or 250 6.7, I am confused? Is one superior to another in 8x10 Use?

    That's for sure, but I haven't seen any evidence in the Fuji literature -- even in a possible error -- that shows the f6.7 with an EBC coating. But that doesn't mean it could not have happened.

    Re: Pinhole size for 8x10" - help needed

    Yellowish glass is one of the symptoms of rare-earth glass -- so maybe the f6.7 has some.

    It usually gets worse with age, but not everyone notices it, and fewer people report that it is a...

    Re: FUJINON NSW ( SW ) f:8/125mm - experiences?

    Also consider the actual hypotenuse/diagonal of your film holders. It will be less than the hypotenuse of 8x10". That's the number you need to compare to lens image circles.

    The 120mm Fujinon has a slightly larger IC of 290mm, but it is single coated and has a larger 77mm filter thread. There are other lens options for 8x10 in the 115-125mm range -- and then there...
  21. Re: Fuji 250 6.3 or 250 6.7, I am confused? Is one superior to another in 8x10 Use?

    There was one f6.7 -- single coated. There were two f6.3 models -- EBC coated. The f6.7 has a substantially larger IC. All three cover 8x10.
