Thread: Super fast 4x5 lens comparison by Bognacki

    Super fast 4x5 lens comparison by Bognacki

    For all you shallow DOF chasers out there this is a great little test done by Jason Bognacki. Includes the Aero ektar, Dallmayer pentac, Leitz (Leica) hector, some Buhl projection lenses and more. Oh, also includes a very cool 165mm f/2.7 Zeiss tessar. I'd love to get my hands on one of those!

    Check out the shots on his tumblr: https://tmblr.co/ZSFHXy22acjuV

    Or look through his Flickr: http://t.umblr.com/redirect?z=https%...VzMmpCTA%3D%3D

    A bad test or bad photography? I'm not sure calling our LF peers bad photographers serves any useful purpose and I'm not going to do it unless they are asking for critique and then I'll get specific.

    Now if someone wants go call Cindy Sherman or Mortensen or Adams bad, that fine as that's healthy debate.

    Nope. I've used the Aero Ektar 7", and still have a 16.5cm f/2.7 Tessar. They are both capable of excellent results, as is pretty much any lens. The test above is rather pointless in my opinion.

    FWIW, here's a photo from the aforementioned 16.5cm lens:



    I would use it more but almost immediately after buying this I found a 150mm Xenotar that was much better suited to what I was doing (handheld work, it was cammed to a Technika), so I haven't really shot much with it.

    Thanks for your images from the BUHL lenses. I use several of them for making images up to the 11x14 format and making Platinum/Palladium prints. They are surely one of the best buys out there. Petzvals bit better but not all that much to be so very overpriced.

    I was surprised at how good my 1927 8" Pentac can be. I do think all of those lenses are capable of great results.

    Someday I'll get around to mounting my Sony 300mm f2 projection Petzval. I have a 5x7 studio camera that might be able to hold it, though I would have to modify the front a little and attach it permanently.

    That is beautiful, was it shot wide open?

    As in, "They're all equally 1% bad"?

    Or, are you just trolling?
