I got the 17 first and also used it with the 1.4xTC, which it takes very well. Once the need came for the 24mk2, I added it to the lineup.
Agreed. The TS17 can become 24 (with 1.4x) and 27 (with 7d) or 38 (with 7d /1.4x) and about 11mm with the shift and stitch. I would rather have the option of 11,17,24,27 than 21,24,34, 53. Often 24 is too long.
However, if don't shoot in the mountains, maybe you don't need 17. In which case the 24 has better iq than the 17 but not by a large margin.
The TS17 is my go to lens. I take the ts17 and 1.4x when I am hiking to save weight. I think the shift is far more needed at 17 then 24, since the UWA affects are greater.
