135/1.8 Sigma ART for Nikon with USB Dock $1300 Three weeks old and perfect condition but I did take it on a trip and it doesn't feel right trying to return it with the typical mild signs of use of a newer lens, no defects, scratches, perfect glass. I love the rendering, sharpness, speed, and build quality but do not care for the focal length. Includes a similarly new 82mm BW F-Pro XS Digital filter (installed immediately) and new Sigma USB Dock. Over $1525 invested. Absolutely clean and definitely a sharp copy, focusing is far quicker than the Nikon 105 and accurate too. Fine tuned using the dock to my D810. Will include original box and materials, USA receipt from MPEX.com(Midwest Photo Exchange in Columbus, Ohio). Please email me for sample images if you are serious (if you PM then include your email address).

I have other Milvus lenses, the build quality is wonderful, lovely lens with great rendering and sharpness. I just don't use it very often. BW F-Pro covered since first minute, filter included. Sent in an OEM Zeiss box sent from Lens Rental but the serial number on the box does not match. Buy this knowing you're getting a good one. Price is NET to me after fees

Also, most of these cameras, whether digital or film, are going to be slow at focusing and have significant shutter lag. Of the newer digital cameras, the Terry Richardson favorites are fairly snappy if they have a nice nice contrasty subject in good light that isn't moving a lot... like a Terry Richardson portrait.

If you already have the Canon 17 and 24 tilt-shift lenses then I'll assume that you must already have a decent Canon DSLR body for them as well... and while the Sony A7/D800 36mp may be a better sensor for architecture than an older 16 or 24mp sensor, is the performance gain really so amazing that you'd invest in an entirely new system from a manufacturer who still hasn't produced a usable range of professional quality lenses and instead forces you to rely upon third party adaptors (that would be Sony)? Won't Canon eventually - like within a year - have a higher resolution DSLR body that can use your fine tilt- shift lenses fully and properly? Without having to stick a wobbly adapter between lens and sensor, which seems like a weak link no matter how hopeful you are and even if that fancy adapter costs $$$. And if you are stitching, then why not simply stitch an extra frame or two and you're capturing the same amount of information as you would from the higher mp sensor? I just hate to see anyone spend money chasing hype. I bet the difference between a Canon 5D2 shot against an A7r isn't going to mean much in your final results. I can't help but think shooting the Canon body with those lenses is going to be very much easier, steadier, and possibly even sharper in real world scenarios. As for shooting 4x5 around TO, there is http://www.elevatordigital.ca/film.html and Bob is a great man. Personally I started shooting only one sheet of many set-ups since my failure rate has dropped with experience, and I like the discipline of "one sheet per shot". It certainly saves money and sharpens your shooting muscle.
