how to work quick shift DA lenses?

[phil r calgary ab canada]

hi

 

got a bunch of DA lenses a month ago and i love them. 14mm, 18-55 & 50-200mm

beauty with my K100d. sooooooooo much fun

 

my old 50mm, 135mm and 70-210 work awesomely too (my photojournalism teacher

called me a maverick for already having too many lenses for first year sheesh)

once i figured out from a forum post that you had to hit the AE lock button in

manual mode to get a metering on non AE lenses -- a function ALSO very scantily

covered in the manual

 

but they are heralded as having the quick-shift focus system.... that's nice

except it doesn't say very clearly at all how to actually use the darn function.

 

is the lens' magical automatic quickshift system know when i want to switch to

manual focus so i can shoot action or sit with it on a tripod? which is what i'd

assume the system was meant for.

 

is it somewhere in the manual that i missed or is there a secret pentax guild

trick to this. now if the pentax guild could just explain how to make my NiCd

batteries resistant to the -10degree celcius cold, that'd be awesome too. thanks

for any help on the quickshift system

 

cheers

No special tricks, just focus manually after the AF has finished wheeling around or when

you get tired of it searching. Although, every time you meter, the AF will reassert itself and

ignore your previous manual focus.

 

So you might be interested in learning about using the OK button as an AF button to

control when you want the AF activated if you prefer manually focusing AF lenses but don't

want it coming on every time you meter (half-press the shutter). It's especially convenient

with the Quick Shift lenses. More on that can be found in the manual and <a

holy thank you so much. the ok button works so nicely. now i understand the quick shift -- very neat function! and the site link had some really great pointers too. getting tired of it searching was a mild way of putting it and now i got way more confidence in autofocus. cheers to you

 

gooday
