    Another interpretation is "I'm intrigued, but reserved".
    Direct translations rarely manage to convey the deeper meaning.

    Re: Gandolfi or not Gandolfi?

    I would say "similar". There are too many differences in the construction, even the brass parts are different.

    Re: 8X10 Lens advice required

    The 150mm Symmar covers only slightly better than an ancient 90mm Angulon: It will get you a picture if you have nothing else, but the corners range from soft to absent. With the right subject I...

    A 210mm Angulon has plenty of coverage, a 165mm just adequate, and a 120mm will cover at VERY small stops. With a Russian 18x24cm plate camera they are all useable. I have used a 121mm Super Angulon...

  14. Re: Do I need macro lens for 3:1 or similar ratio?

    Not quite. The old Schneider Symmar convertible lenses were optimised for 1:3 instead of 1:10 or 1:infinity. That was done as a compromise, in an attempt to make a lens that would work equally well...

  16. Re: Voigtlander Petzval or Euryscop? Can someone please help me identify what i have?

    Re: Wide Angle for 12x16"

    An old 210mm Angulon will almost cover at infinity - corners are soft, but not enough to be a problem on a contact print. At 3m distance, it will cover just fine (at small apertures).

    If it originally held a Symmar 360mm f:5,6 convertible, I think it's a V, not a IV.
