Frage von eXp:
hello people,
I'm looking for a good wide angle lens for my pentax Kx (APS-C sensor).
I've been following objective put into the fears either.
- S.meisten Sigma 20mm F1, 8 EX, is objectively interested me until now that: Wide angle good, Depth of aperture and thus a minor.
Unfortunately, I've read through the glass far more bad than good.
- Sigma 10-20mm F4-5, 6 EX, will be a very orderly objectively, however, is not the brightest and do not leave much room to play with the sharpness to "".
And das ..
- Tamron 10-24 mm F/3.5-4.5
has not collected one experiences with the glasses? especially with the 20mm festbrennweite of sigma?
or else do you have other recommended alternative?
schonmal thank you!
David
Antwort von srone:
Sigma 20mm F1, 8 EX ... aperture and thus a small tiefenschärfe ... at a focal length of 20mm can hardly be of shallow depth of field (and not "Depth of" that's something else to talk) and it is synonymous ever so bright, because more wide-angle (which has a much greater influence than the luminous intensity) the greater depth of field .

You Kuck Tamron 20mm zooms in on - which are moderately announced price / performance. And you get synonymous WW.
Or buy halt ne good old manual Pentax Lens've finally ne - who needs new lenses, even if it could get old super manual of good hand. ;-)

@ SRON
So I know it so the tiefenschärfe and depth of field and is the same!?
enhanced when the 20mm sigma of a maximum aperture of f1.8 has left to me (at least if the object is not removed allsoweit) is playing with more sharpness than with the 10-20mm with a maximum aperture of f4.0.
Another small advantage of the 20mm, is the manual blinded, which allows me to knipse in exposure to trick something.
@ B. DeKid
jaaaa, that would probably be best to have indeed been synonymous of a manual 50mm f1.4 pentax.
but so far I have not found one under the old very wide angle.

Where is the difference between the depth of sharpness and clarity of the Depth?
