I think it was gerald.d that posted a very nice comparison between Digaron-S 23mm and Canon 24 TS-E on an Alpa FPS. At f/8 the Digaron-S blows it away, still better at f/13 (or was it f/11) but then the Canon is quite close and diffraction is still not too bad. If one thinks it's good enough is personal. I think having great sharpness at f/8 is overkill, as f/11 is my preferred shooting aperture for MF, or else DoF becomes a bit too difficult to work with in most situations I think.Can the Canon 24 really hold up to an IQ180? It seems intuitively more likely that a Rodie is going to do much, much better, admittedly at the cost of having to do LCCs...
The 23HR is, if anything, better than the 40HR regarding sharpness and bite. But of course with a smaller image circle (see comparison of tech camera image circles here).The 40mm HR is the best lens I have ever used, in any format. It is not close. If the 23mm HR is as good or at least close to being as good then it should blow away any extreme wide angle ever made.
I have the 24 TS-E II and it works best at f11. Its good in the center at all f stops but in the borders and edges (on a 24x36mm sensor!) and when shifting, it only gets really good at f11. At f16 diffraction has set in.
The 40mm HR is stunning at all f stops and its only diffraction limited..
With two mounting blocks the Cambo STC will mount vertically or horizontally with the same ease.2) the cambo wrc400 seems nice in that it has 'natural' rise whereas the STC requires the camera to be turned 90 degrees if you want rise. I use rise a lot more than shift. Is the STC easy to use that way or does it feel strange ergonomically?
With a Full Frame sensor (e.g. IQ260) the 23 has no meaningful shift (like you said, 2mm maybe).The Rodie 28mm is extremely sharp and maybe the sharpest lens I used with my Tech cam was the SK 60 XL. Frankly if it was me starting back up I would not get the 23 as it has no movements really 2mm maybe. The 28mm you get about 7mm so you could stitch a little if needed . Than I would get the 40mm, 70mm and 120.
If you are diligent about turning off the IQ back between a sequence of shots then thei answer is no. However, for the very best results without fear of heat noise accumulation then yes. It's easy to forget to turn off the back and it can get warm - normally when you least want it to. I use the auto off feature anyway as a backup.Do you really need a wakeup for the IQ180? What's the gain? I thought that hack was for the P45+.
Here's the latter test -I think it was gerald.d that posted a very nice comparison between Digaron-S 23mm and Canon 24 TS-E on an Alpa FPS. At f/8 the Digaron-S blows it away, still better at f/13 (or was it f/11) but then the Canon is quite close and diffraction is still not too bad. If one thinks it's good enough is personal.

Anyway 24mm is a lot wider than 40mm, probably not what you are after. For the 40 you'd look at HB V 40CFi it the proposed FPS system, I have no idea of how that lens will perform, but typically retrofocus SLR-type of lenses are considerably weaker than tech cam lenses. They are often also rather expensive...
Tim,I hear that the Rodie's need to be shot at F8 thru 11 whereas I was comfortable with the SK at F16 if needed.
Tim,I am getting so fussy - turning into an 'old woman' - today I was looking at some shots I made on an M8 with 90mm Macro Elmar and for the first time I noticed a subtle colour shift in the sky. Where will it all end?
I agree bite the bullet and buy an SB from the get go. You then are free to lock it to a 34mm adapter and carry on as if it were LB, or... put it on a 34mm TS adapter or... two 17mm TS adapters for 2 directions, or... use it with an FPS. (no LB lenses can be used on an FPS)...and a long barrel Rodie 40 which I can later convert if needed (trying to find out what that costs and how long it takes!)
