I had bought the 7D with the excellent EF-S 15-85 a close equivalent to the 24-105. I loved the range for travel and it’s sharpness. 15 mm is very different to the 18 mm offered in standard kit lenses to the point I will not move to RF-S if it doesn’t come out or at least a 15-65 mm which would be the true 24-105. Having to buy the RF 6 and 24-105 is a totally different budget as well as all other replacements to my other 4 EFS lenses. I want to move for lighter equipment without necessarily having to go to FUJI for that although their 16-80 would suit me too. EFS 15-85 was great for all its users but Canon never promoted truly after its launch on 7D, I hope it’s not disregarded for RF-S.
