I've been doing some food photography with the 100 macro lately, and the DOF limitations have gotten me thinking about TS-E's. What are people's thoughts on getting the 90 versus the 45 with a 2X telecoverter? Seems like the latter would be more versatile, but is there a big IQ tradeoff?
Huge trade off, don't do it. The 90 is a very sharp lens, the 45 not so much, with the 2x convertor the 45 becomes practically useless.
If the lens is less sharp than the camera, there's no point in using a TC, just crop it and you still have a better quality.
