In order to become useful for macro photography we need much more than 8.5° tilt.
I have the 90 TS-E, and use it much more than the 100mm Macro for flowers close-ups (with 12 and 25 mm macro tubes), it's über-sharp and a joy to use, but I wish 3 things could be improved :
- separate tilt/shift function (I assume the v2 will have it).
- slightly closer focusing distance (at least 1:2 instead of 1:3)
- improved tilt capacity (more than 8°), but that will be at the cost of the relative compactness of the 90mm, since the lens will need a bigger optical circle, which means bigger lenses.
- I was quite happy with the 90mm focal, doubles nicely from the 45TS-E. 100mm TS-E Macro L
sounds good, but I hope they won't turn it into a 135 or 150mm, that would be too long for a true close-up/detail/studio/ architecture all-rounder.
I hope we do not end with a 3lbs, 3000$ monster.
