k-x and tamron 90mm

Hi all,

Picked up a tamron 90mm for some macro work, and have a quick quiestion regarding the aperture setting. Most of my other lenses do not have an aperture ring, whereas this one does. Do I leave it on A and set aperture via the body, or set via the lens ? Do I need to set the menu item to allow the aperture ring to be used ?

cheers

Leave it on A if you want to control it via the body. Much easier.

Control it on the lens if you don't want to control it on the body, or want to use the lens on a non-aperture control body (like an older film body). If you want to use it on the lens on the k-x, then the camera settings menu tab 4, last item #22, Using Aperture Ring set to option 2.

Cool, thanks for confirming. Will set it so I can use on the body and get a few macro shots up soon.

Good luck with the macro shots. If I may provide suggestions:

Tripod
2 second delay shot or 3 second remote delay shot
Some sort of additional lighting (whether macro flash or some external light source)
F8 if you don't want even a hint of CA, F5.6 if you aren't shooting anything super reflective, F2.8 if you want hell with the super thin depth of field

Good advice from JinDesu. A note on tripodding: When the camera is immobilized, be sure SR is switched off. If you use a remote, or time delay, or B mode, the camera switches SR off automatically. If you are 'podded but you finger the shutter anyway, you must switch SR off yourself. Have fun!
