Originally posted by dammit_jill It looks like I'm looking for speed more than anything. I'm always on the go and candid shots, well, I got to be fast in low light that's for sure.
Pentax are notorious for being slow in AF in low light levels - there is not that much improvement going from a K100D (Super) to even the top of the line K20D
note the horizontal scale of the K20D is misaligned it should be the same as all the others.
(crops from certified test results from Popular Photogrphy)
The other well known brands are faster in lower light levels - but we are still talking in the order of about 3/4-1 sec to auto-focus - which is simply
NOT fast enough to catch any action.
This is the misconception that faster automation is a panecea for
ALL problems.
So how did photographers from years ago ever manage to capture action with manual focus lenses?
and there are lots of example out there including acknowledged masterpieces....
Almost
ANY AutoFocus is faster than we can focus manually
- so why aren't we doing any better? ...
Did photographers from years ago with manual focus lenses wait to see the shot and then tried to focus to take the shot?
I know, that sounded absolutely
ridiculous -
of course not, they pre-focussed their lenses and waited for the shot
then it was only literally tripping the shutter.
Use the same technique -
Pre-Focus - by light half depression on the shutter button, hold that focus, re-compose, and wait for the shot - when the shot is seen, fully depress the shutter button, then the delay or shutter lag is less than 0.1 sec which is faster than human reaction time
or any AF...... under any lighting condition.
Originally posted by dammit_jill I'm going to try out going after faster glass and see if I notice a difference. Otherwise I'd just return them
You already have one of the fastest glasses avaiilable in the 50mm f/1.4 .....
Originally posted by dammit_jill I do notice ALOT of noise at higher ISO for the k100dsuper.
Yes, well, noise at high ISO is inevitable -
The Pentax K100D (Super) is actually very good at high ISO -
there aren't that many dSLRs that are noticably better -
yes, some Full-Frame dSLR (but read expensive - and the Full-Framed Sony A900 is not that great in high ISO noise)
and perhaps the new Nikon D90 and D300 does show improvements
- but not much else.....
