Yea but the Hartblie is not as wide as this Canon 17mm. Also Don do you think it maybe better IQ wise. I have my doubts honestly.I'd do this in a heart beat if I could only find IR filters that were that large! In the end it looks like the Hartblie will work better for me and allow me 2-seperate syatems for it to work on....
Guy I understand the concerns however shooting IR is a little more forgiving. Base on previous experience with a Hartblie when I was shooting with a P45 I had no concerns on the IQ. My main thought is that the 45 is equal to 28mm on the 7R and that with shifts I'll be able to pick up wider (maybe not as wide as my 14). I'll also be able to put it on the DF so I get (I hope) the best of both worlds. While I see this sitting on the Sony most of the time it'll be nice to have it there "just in case". I've got the newer lens coming to me so later in Sept I'll be able to share.Yea but the Hartblie is not as wide as this Canon 17mm. Also Don do you think it maybe better IQ wise.

Seriously this lens is hot ****. LOL
No trouble with finding 82mm filters it became a PIA when trying to find larger which thankfully I don't need.did you try filter connection for 82mm filters?
Yea they have a 82 ring that would work fine for the 24mm. The 17 is more the problem child. Why I figured to go the 100 mm and 105 Cpl. I know I'm perfect for the 24 with no limitations but the 17 I get 5mm of rise and fall which will be fine and keeps me from buying the 150mm units. The 17 I know I can deal with that but the 24 I know I would want full movements. The one issue I was worried about was the 24mm TSE was if I stacked 2 82mm screw in filters I would run into vignetting and maybe even one for that matter, not sure. My reasoning for jumping up to 100mm. I know that will cover anything I do with the 24mm. I look at the 17 more as the interior lens and the 24mm as more the landscape lens. But I do like a super wide sometimes doing fun stuff with landscapes. I'll see how it goes with the 17 and worse case i will keep the 100mm system for 24mm and above lensesfor my cambo rig i use the Lee wide angle compendium bellows with a variety of adapters to fit my lenses. polarizer is 105mm B+W and i use Schneider 4mm thick 4" sq glass filters, 4 x 5.6" GND); will figure a way to fit that to the 24mm lens next (looks like an 82mm wide angle Lee adapter would work, but this setup is too small for the 17mm
Thanks Chris. Well being the old dog I came from 4x5 view cameras but in digital I also used tech cams quite a bit so you do get used to it. A lot of people go by numbers a great deal trying to figure out the formulas and all that. God I hate that stuff. I go by the rule of thumb here and let me say very clearly this is WHY i bought the Sony in the first place was focus peaking, magnified view and very very good Live view which makes this so much easier. I came from MF digital backs and none of this was available it was guess work and still is to a large part. But the rule of thumb says pretty much for every 30mm worth of focal length standing at a normal height than 1 degree of forward tilt should get you pretty much right on the money. Now the 17mm with the same basic guide would be a 1/2 of a degree. Now as you get lower the camera that is to the ground this will slightly increase and you get lower , now that makes sense since your angle is getting getting smaller.Guy - your image samples here look great. You seem to be getting a good grasp of the tilt feature for getting near and far subjects in the same focal plane, which is something I still struggle with. I have played with tilt on flat landscapes, and with the 17mm I noticed that one needs very little tilt (about 1/2 degree based on 4 ft above the ground) to make a difference. The tilt feature is much more useful on the 24mm lens, where a 1 to 1.5 degree tilt can bring near and far into focus (at 4 ft above ground). By the way, after researching the tilt feature on for my 17mm and 24mm TSE's, the best demonstration of how to use tilt is this video from Darwin Wigget of oopoomoo: youtube.com/watch?v=kOQsxbYs4gM
