Originally posted by Laurentiu Cristofor Yes, I guess I had my scenarios in mind more than yours. My "focus challenge scenario" is available light portraiture and in that scenario, with thin DOF it makes a difference if you focus on the eye or on the brow - the focusing point can often overlap both, as it is not easy to keep it just over the eye if the subject is moving
. This is also where focus peaking was failing - it was highlighting both the pupil and the brow and the highlight over the pupil was not easy to notice either.
Very nice work! I never had a lens that is suitable for this scenario. Speaking of lenses, which Pentax lens would you plan to use for such work?
Hi, thanks.
Yep, that's why I included the samples, it's normal that when we're giving an opinion we're thinking in our own situations.
I understand your point about peaking, that's also why I said before that in it's current state I can't use it for action, or I can but not so well as trap focus.
BTW your experience with peaking is with Sony or Pentax? IMO both systems has it's strong points and weaknesses, but I think Pentax is probably better for your use.
In theory (because I never tried it), I'm not so fond of Pentax because of the lack of color choice, in fast action I think it would be difficult to notice Pentax peaking. But I think it's a more sensitive and precise peaking than Sony, because unlike Sony it appears to work in both vertical and horizontal axis.
I wont be using a lens, I'll be using a telescope. It's what I've been using for a long time, a 480mm F/6 triplet apochromatic telescope. The IQ of this thing is really good, and that's in part why I refuse to use AF systems, it's hard to find an AF lens that can keep up with the optical quality of this scope, at least at a reasonable price
And with a body that can give me realible CIF I don't see the need to have AF.
