comment What's wrong with my Sigma 18-250mm lens?
yeah, apparently SE user Mike Sowsun provided a better, more explanatory answer. - User Slava can still try to set ISO higher to check if the lens/camera combination still can yield properly exposed pictures, (which will be noisy, though)

comment What is common practice w.r.t. providing signatures on printed photographs?
I meant to say "rubber stamp on the back" instead of just "rubber stamp". It might provide more info about technical process involved (e.g. the lab, quality-control)

comment Can a Sigma dp3 quattro be used for Macro Photography?
I meant Superresolution. Maybe it can be used here for noise reduction and some resolution improvement. Never tried it, only know that this method exists. Didn't remember its name yesterday. To me it's like focus-stacking with focal plane held constant, and then different algorithms applied.

comment Can a Sigma dp3 quattro be used for Macro Photography?
that's the extreme case. my objects are larger. and there is still the option to apply a focus-stacking technique.
