If one starts off fresh, they just need :
Samyang 14/2.8 (works very well on FF)
New DFA 24-70/2.8
That covers as wide as most people need at 14mm and a very reasonable skip to 24mm (on the zoom).
I use a 12mm and then a 24mm UWA prime combi very often for travels.
In fact, in places where thre are wide expanses of land, 14mm may be overkill.
The zoom provides all the focal length one generally needs too and at f2.8.
Alternatively, one can just get the Tamron 28-75/2.8 and give up the 24-27mm for a cheaper option.
So, a FF even if starting from scratch, does not cost that much more than an APS-C, certainly wider for cheaper.
Oh..yeah.. add a rather cheap DA 55-300 in crop mode if one wants long reach.
Originally posted by biz-engineer Thanks for sharing, interesting examples. Overall you get very decent results.
Questions: are you referring to color filter stack on the sensor itself? How did you manager to get two different A7 models?
I sent my camera to Kolari Vision which pioneered the thin filter replacement and my brother (another Pentax user who got A7 for his Pentax lenses) has the unmodified one.
AKAIK, its the overall thickness of filters on-top of the sensor. ie. color filter, AA filter, UI/IR filter.
