to Oranges again, but as Thom
has said well, photography is a balance of "Chasing
Perfection versus Balance". That's exceptionally true for those of us
doing expedition photography where weight is of paramount importance.
Especially since I really only use the Samyang 14mm f/2.8 for shooting
starscapes as it has so little coma.
Today a quick side by side look at the petite new Samyang 12mm f/2 on
the A6000 and the more well known Samyang 14mm f/2.8 on the Sony A7.
Really the only two modern, cheap and fast ultra wide angle rectilinear
lenses. The aperture difference helps the sensors come near equal as
the A7 is about one stop better in low light. Of course the 12mm f/2 on
the A6000 comes out to ~17mm in full frame so it's not exactly equal.
Neither is the weight or size as can be seen above. Plus the 12mm f/2
can take 67mm filters, a nice advantage. Both
focused to infinity with cameras set to sunny day white balance and
exposure matched at ISO 100.
