New Unique Macro Coming? [CR1]

sabaki, the only things affecting depth of field are focal length and aperture - no free lunch in macro world.
A 1:1 TS macro would be cool, popular with product photographers, most of whom swear by the TS-E 90 +/- extenders. I would guess that 90 to 120 mm would be the sweet spot. I would like a 300 or 400mm 1:1 macro, perhaps by having swing-in elements or a converter with glass to cover the 1:4 to 1:1 magnifications. (It would be great for those head shots of rattlesnakes and cottonmouths. Really. I currently use the 180 plus 1.4x TC, and even that is slightly closer than I would like.) It needn't be continuously focusable from infinity to 1:1, if that presents a design issue. I admit that I would like a lighter 180mm 1:1 macro with IS, but the IS would be more for the 1:3 and lesser magnification, because IS doesn't do much at high magnification. Speaking of which, I wonder how in-body image stabilization (sensor position adjustment) would work in macro. Sony A7II users?

I am not sure that any of these are truly unique. The MP-E 65, now THAT'S unique!

This constant clamour for T/S macro lenses displays a remarkable consistency for failing to grasp how tilt works and the intrinsic limitations of tilt lenses on cameras with deep mirror boxes.

Sure, the 90mm TS-E is a wonderful product lens and it is often paired with extension tubes to reduce minimum focus distance and increase magnification, a 25mm tube gives you a 0.6x magnification, but tilt use becomes limited at these distances because of mirrorbox shadowing and if you look at the classic 90 TS-E + tube images they are all done with the camera tilted too.

A 90 TS-E MkII with a closer focusing distance, yes; a T/S Macro (1:1) I think is highly unlikely.

My question is, would it be possible? If yes, Canon may charge another $ 3,000 for this lens. ;)

The point here is that right now everyone is simply speculating what the new "Unique" feature would be. If a certain lens design is technically not possible, fine, let's speculate on something else. However, if a lens design is possible even theoretically, why dismiss it altogether?

My 15mm f2.8 fisheye with MFD of 15cm can focus as close as a macro.

Yes, but can you get 1:1 magnification? :)

Not sure how serious you are, but isn't a fisheye macro oxymoronic? 'True' macro implies 1:1 magnification of the subject at the sensor, but a fisheye has the widest field of view of any lens type. How could you have both simultaneously? My gut feeling is it's physically impossible, but I'm not an engineer.

The lens would have to be practically on the subject itself I imagine, it does seem oxymoronic I agree which is why I mentioned the idea in the first place :)

I would like to see a 1-3x Macro, 90mm or greater, 150mm preferably. The 3-5 range of the MP-E 65 has such a steep learning curve that if they would make a baby brother with a longer focal length I believe that would appeal much more to many macro shooters.

TS stands for Tilt/Shift - Shift isn't really needed here - and itcosts to build a bigger circle of light.
Maybe only a tiltable frontlens, but enough to tilt the focus plane to 90°. On Ultrawide there is only a small angle needed, I don't know, hoch much for a 100+mm lens. And rotate in any direction, so you have the chance, to tilt in any direction, not only 30° steps.

A 90mm TS-E lens with greater magnification has been rumored for sometime, but it would not count as a unique macro. Nikon's PC-E 85 already is .5x. I suppose it is possible to increase the magnification beyond that, but I am not sure the need is there.

Canon could release an update to the MP-E 65, but I doubt that. The current copy is still extremely good and Canon has absolutely no competition in this space.

Another possibility is a low aperture macro. The lowest one I am aware of is the Zeiss 100/2. Still, low aperture in macro if mainly for very abstract photography. I do not believe there would be a huge need.

Finally, Canon could create a >200mm macro lens. A 300/4 macro lens would be intriguing, but I question the market need. Already the 180mm is a niche lens - suited for specific types of flowers and insects. For many uses the 180mm is too long.

Note that I currently own the 100/2.8 IS, MP-E 65, TS-E 90 and have owned the 180, so I would likely be a prime customer for any new macro. That being said, I suspect this rumor is untrue. I know Canon has patents for new macros and may have a prototype or two out there, but I do not believe the market is large enough to actually release something. Most likely Canon will update the TS-E 90 and the 180 (IMHO the poorest resolving of the macros) within the next few years, but their more innovative lenses will be in the more widely used lenses.

I have a Mirex Pentax 645 to EOS TS adapter and I have experimented with the Pentax 120mm Macro with it. Indeed the problem was the amount of limited shift I could get without severe vignetting.

I was able to "gain" about 1 to 1.5 stops of increased DOF. So instead of having to use f32, for example, I could use f22 to get about the same DOF but almost no noticeable improvement in sharpness. To me, this wasn't a big enough gain to make it worth the effort. That is not to say some combination of focal length and TS design couldn't improve on that.

But....

Putting the same adapter on the EOS-M was a different story. Not only could I use the full range of the adapter to get usable focal plane changes, I used a tripod mount on the lens instead of the camera the usability goes way up because I was moving the camera instead of the lens and the lens could stay pointed at the subject.

Macro is all about sharp pixels on the subject. it usually makes more sense to use a smaller sensor for macro since shallow DOF is less of a problem.
