    Anastigmat versus Tessar lenses

    I'm looking at two identical cameras, one with an Anastigmat lens and the other a Tessar. Which is better overall.

    The anastigmat will be a bit softer, the Tessar will be soft wide open but sharpens considerably from f8 on up.

    according to this http://throughavintagelens.com/2009/...astigmat-lens/ the tessar is a development of the earlier anastigmat -- tessars have a better reputation. Given the choice, all other things being equal, I'd go for the tessar. If it is softer images you want, whack the enlarger during the exposure.

    Anastigmat is a generic word that has included many more specific types of lenses, fine and inexpensive. If possible, taking photographs with both cameras is the best test of both lenses and cameras.

    Not in my experience. Both seem to perform about the same, and the softness is something I read a lot about but never found all that annoying.

    Lens marked Tessar is likely slightly newer than one marked Anastigmat.

    Not neccesarily. I have a lens marked "Zeiss-Kodak Anastigmat" It's a 7" f:6.3 Tessar. Another marked "13" Eastman Anastigmat" - it's an f:10 Artar type process lens.Scary sharp. Yet another marked "Goerz Double Anastigmat" - we all know what this is.

    Unless the OP gives more info. about just which anastigmat he has his question is unanswerable.

    To add a little, the name anastigmat has been applied to many design types. The name refers to a property -- well corrected for astigmatism -- not to a design type. All tessar types are anastigmats, some anastigmats are tessar types.

    Spoolman, if you want advice that's safe to act on, you'll have to tell us more about your Anastigmat. Other markings on the face plate, who seems to have made it, which camera it is attached to, ...

    If you're looking at old Kodak folders, anastigmat covers a lot of lens types, including tessars, triplets, dialytes.

    Anastigmat versus Tessar

    The specific reason for asking this question is that I'm looking to purchase an Ihagee Parvola 3x4 cm camera. I have a choice of two. One has an Anastigmat 70 mm lens and the other is a Tessar 70mm. The price difference between the two is significant. The camera with the anastigmat lens is $80.00 cheaper than the one with the tessar lens. I will be using one of these cameras for everyday street photography and I just needed to know which is the better lens for rseolution and sharpness.
