Hi glo, thanks for your question. I just bought this DC about 1 week ago, at this time I mostly use the auto aperture and shutter, only sometimes use EV compensation. Due to the limitation of this DC, even for manual aperture, for tele say 112mm, it allows either F4.8 or F9.2. Back to this photo, my target are the reddish-brown rock and their shadow which make me feel quiet which also attract me to take. I guess if F9.2 is used, those green trees will have more details, but for the background mountain, as it is much foggy than the trees, there will not be much improvement. But honestly speaking, if you don't ask, I will not have this analysis. At that time, I just found the result was what I needed. Thanks again for your question which make me have more thinking.
