  1. Re: Lens length preferences in 7x17 format?

    Jim, have you tried a 190 Wide-Field Ektar? 5x12 and 7x17 have almost exactly the same aspect ratio. So doing the math: (12/17)*10.75*25.4 =193mm so the Ektar should match the view of your 10.75”...

  4. Re: Mounting a threaded filter on a lens without conventional threads.

    Adam at SK Grimes can make you a slip-on threaded adapter. In that size I guess it'll be in the $100 range, plus or minus, and you might need a different one for each lens unless the outer rims of...
  5. Hinge the window on the top or the side - or does it matter?

    While watching the George Tice video on the B&H You-Tube channel I noticed that at least one of his images had the window hinge on the side of the mat. I've always put the hinge at the top because...

    Something I did on a recent rainy day. It was lit using a fiber-optic illuminator about a foot away, which acted like a point source. This was my favorite of several "poses".

    Re: 300mm lens 4x5" landscape

    Any 300mm f/5.6 lens will be in a Copal 3 or comparable shutter so it will be big and heavy.

    Re: new (and first) 4x5 camera

    The Intrepid has a lot going for it as a first camera. It's inexpensive, decently made, and as you're in Europe support isn't that far away. If you buy a new one you'll get the latest version with...

  23. Re: Longest focal length telephoto lens with bellows draw under 300 mm

    The 500mm f/9.5 Tele-Congo has a 287mm flange focal length according to my notes, which would give you a closest focus of around 20 feet or so without an extended lens board. It just covers 4x5...
