SMC 50mm A 1.7 - WOW !!

simonkit · 12-04-2007, 12:41 PM

Just received a used 50mm 1.7 lens I bought on ebay for very little and I'm extremely impressed, sharpness is something else.

One minor problem, probably just me, but occasionally it won't take the shot when the shutter release is pressed - do I need to change any in-camera settings etc ?

thanks

Is this when you are taking a number of shots in rapid sequence? It could be the write time to the card.

Thanks - just had the answer from another forum. I still had the selector in "SAF" mode, changed it to manual mode & problem solved

which camera you are using? AutoFocus? so maybe it is just hunting the focus :P

I'm using the GX10 (K10D clone) - the A lens only works as a manual focus lens, definitely because I hadn't selected "manual" on the selector

thanks

Pretty amazing lens for very little cash BTW !!

That´s the cool thing that´s called the "focus trap" on Pentax bodies. I sometimes use it with manual lenses when focusing is tricky.

As you say, when camera is set to AF with a manual focusing lens, the shutter doesn´t fire until you have focus.

Very useful at times.
