I use both T3 and TC, have two bodies of each. Only one of the four has an accurate meter - a TC. I really do like the T3, a lovely winder. The TC has a loud shutter and somewhat dim finder. T3 is better. I use the 135 f3.2 a fair bit and it is just lovely. Not terribly keen on the 28mm, the most common lens it seems. I find it very hard to use the 21mm f4 on the TC - cant read the display in the viewfinder. Better on the T3. Actually, the T3 is rather good. Definitely keep using it.
