So I have the 358 but want the 1degree spot meter function of the 558 and 758. Someone will sell me their spot attachment for $65. Since I paid $200 for the 358 mint it seems like a good deal but I also found out that u have to look at the screen every time u meter and it's not in the spot viewfinder. Doesn't seem like a huge deal but would it make sense to just grt the 558 if I don't need it to do custom calibration to my exact camera? Or stick with the 358 and spot attachment for the price?
Btw/ I want a spot meter so I'm not having to use th 70-200 in spot mode just to get a couple values if I'm averaging thrm out.
