I just used that as an example from a google shopping search because I cannot remember where I saw it for £400 ish.
My cousin has a Sony A350 and bought an amazing 50mm F2 digital prime lens for £99. I haven't looked recently but cannot find one for a Pentax fit.

Adqam, I just found it. The 'wireless' setting in the Fn menu. Thanks!

Yep, if you set it to Av it will meter and shoot with the lens held at the largest aperture.
If you set it to M, be aware that some trial and error may be needed to get the exposure right. I find that the camera's idea of the right shutter speed can be slightly off (and I know it's not a fault as most others have it too).
When you're focussing manually look for a little green hexagon in the viewfinder, this confirms that you're in focus.
If you decide that you like the lens, have a look for the Pentax-A 50mm f1.7. It's the same lens but with the A position on the aperture ring, so it'll work with all the modes on your camera apart from auto focus.
I have seen that lens. It is about £400 though! I need a 10-24 before I buy that!Yep, if you set it to Av it will meter and shoot with the lens held at the largest aperture.

If you want to give f/1.7 a go, I would advise some kind of focus aid - either a magnifier; such as an O-ME53 or Magnifier FB; or a focussing screen with split prism, as it is really easy to stuff critical focus in these cases!
If you are using P-TTL flashes, you can set your pop up flash to work as a controller.
I am using P-TTL flashes. I find using my pop up flash to trigger them affects the image and it annoys me. Although I did try it with a home made reflector that reflected all the light behind but it still set off my hotshoe flash that was on the floor 3 foot infront of me. chris9486 wrote:

I am planning on getting an infra red trigger once I get my own studio flash kit. I don't know why they don't build these into them. Well I do know but still, they should!
f/1.7 will give you extraordinarily narrow depth of field. With studio work, f/5.6 is a more typical aperture. This aperture (or thereabouts) will give you maximum sharpness.Ok, I am doing some shots possibly for a promotion for an opticians. So I am going to be close to the eyes and want to play with DOF.

I think I might use my Sigma 50mm then purely for ease of use. What would I use F1.7 for then?

Thank you all for the great replies!
Ian was right about this place!!
Ok, it works! I didn't think to hold the shutter release half way down. My viewfinder does go a little dark and then shows me a shutter speed. This is in Av. I will play about with it in M more.
I will be shooting with a home studio flash kit with an X sync cable (I am new to using flash kits) and want to know, will I have issues with using this with the lens? It doesn't do the swishy thing with the green button in X mode. I do have a 50mm Sigma EX F2.8 that I can use instead, I am thinking this might be much better for studio portraits. I have two models booked next week for location shots. I am assuming the 50mm 1.7 will be better for this as I will be using a 43" reflector instead of flash.
Thanks again.

Hi John, thanks for the quick reply. This is really going to show how little I know about my camera.
I made a very stupid mistake originally, I still had it in AF mode because I was so excited to use it I just switched lenses without thinking.
I have no idea how to do any of that. I have tried it and would like to learn it if it will help for using the lens. I am assuming the stop down lever is turning the on off ring all the way around to the preview method? If so, it was set to live view and I changed it to the others and tried what you said but it still isn't getting a meter reading, or at least I don't think it is. Would it show it in the F number section on the top LCD if it did or would the shutter speed be jumping about if I point it at other things (because it has been doing this all along). As for the green button. I have it, I just cannot fathom what it is for. I wouldn't consider myself thick, but I just cannot understand the manual and have never felt the need to learn what this button does.
Also I changed the drop down menu when first posting to the lenses section, I mustn't have done it properly.

Hi, I don't know if I can ask this here. Normally use the 'other' Pentax forum but some people are rude.
I have borrowed the 50mm 1.7 Pentax Asahi Lens ( this ) from my cousins Pentax film camera as I am doing some portrait stuff later this week hopefully. Well I cannot get my Samsung GX-20 to take a photo with it. I went into custom menu 2 and changed the 'Use Aperture Ring' to ON. It also asks me focal length when I start the camera for image stabilisation. Can anyone tell me why it wont work with my GX-20?

Don't wanna pay £350 for a new one as I am poor and cannot decide between the Sigma or Tamron.
