here are a couple of 100% crops of the 450mm and 600mm
Forgive me for asking, but is it just me or is there a substantial IQ loss between those two images? The 600mm seems very soft.
Thanks for sharing and enjoy the xiao long bao while you are in Shanghai!
it is, I think there is a bit of camera shake in the 600mm image as i was trying to hang out of the 12th storey window as much as possible with the camera and lens and was not using a strap
this is the reason i posted the crops not sure how much is due to the lens and how much of the loss is due to the operator
all the BIF shots i posted before are 600mm too but dont seem as soft so i think its more operator than lens
