27.2-88 f/4.48 would be equivalent for taking identical pictures.

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.
Comparing noise at different resolutions makes no sense whatsoever. My one pixel camera has no noise at all, even at very high ISO; will you buy it from me?
