Please keep the feedback coming. I'm noting it all.
I'm also grinding through mountains of older posts under various search constructs, and from that reading, another related question has emerged:
Some ART 1.4 buyers complained of bad focus out of the box. However, instead of sending the lens back, they instead used the Sigma Dock to tweak the lens. Coming from a 1970's era initiation into photography, this business of being able to hook a lens up to a computer to adjust it is still very Flash Gordon to me, so the following question might be kind of dumb, so bear with me...
If a micro focus adjustment (MFA) is made only to the lens, based on it's performance with camera A, then what happens when that lens is attached to camera B, where cameras A & B are not only different cameras, but are also from different generations?
I can get my mind around making an MFA in a body (even though most of my bodies do not have this feature), because the lens can remain the same, and gets interpreted differently from body to body (if I understand this right). But if a lens is "tuned" to one body, and the optimization of that tuning takes the lens towards the extremes of it's adjustment scale, then what happens when the lens is attached to a different body?...Show more →
That is a great question. I guess the theory is that the lens will behave the same way on every body, and the AFMA on the bodies takes care of any differences between the bodies themselves.
