Four photos to be proud of - each one of them very good

From a pure landscape point I think it would have to be No. 3 - great composition, spot on exposure and a lovely feeling of atmosphere.

However No. 2 is the one I'd have hanging on one of my walls! I just love the bleak simplicity of it.

Hi Paul,

You're most welcome - I'm glad you've managed to get them working (all be it with certain lens restrictions).

You may find that they could be just the excuse you need to buy an a nice A 50mm 1:1.7

Hi Paul,

I have only used the tubes with lenses with an aperture ring and set the required aperture on the lens and not the body because of the very problem you are having now.

From my experience if you set the lens to A the lens will always operate fully open as there is no aperture control from the body this is why you see "F--" as the aperture setting. If you are using a DA L lens it will only ever be fully open.

Regardless of the aperture setting on the lens the camera holds the aperture fully open until the shutter is fired. Using the green button when in M mode closes the aperture for metering ie "stop-down metering". You can hear and see the aperture closing down to whatever it is set to on the lens. The shutter speed will adjust apropriately depending on the aperture set on the lens. It's just like using AV mode except that you have to press the green button.

The pin you refer to does retract on my A 50mm but not my FA 50mm and they both behave in the same way when mounted on my K7 with the extension tubes.

I think that the removal of the paint does nothing other than fool the camera into thinking that a lens is attached.

Are you using M mode and stop-down metering?

Regards

Hi Paul,

Here's a photo showing the area of paint I removed from mine.

The lens on the left is the A 50mm 1.7 that I use with the tubes. I compared the 2 mounts and removed the area of paint where the A contact is.

You do need to have the "use aperture ring" (or the Kr equivilent) set to permitted in the menu and use the camera in M mode.

I hope this helps

I should add that 5 shot bursts are usually cleared in 3-4 seconds and a subsequent burst is back to the highest fps rate.

I get about 15 RAW files in a burst (at maximum fps) with a class 10 Sandisk Extreme card with my K7 before any noticible reduction in burst speed. Then it slows to a crawl. I'm afraid I don't have any slower cards so I can't compare.

I would hope that the K5 should have similar or better buffer and write speed performance than the K7.

I don't notice any metal on metal rattling with the L plate. Won't it be the same with the Sun Sniper fixing? It is a metal ring that you're connecting the strap's karabiner to.

I am using a Q Strap sling strap. It uses a metal baseplate and they can be purchased seperately.

I have been using it for a while now and am very happy with it.

Great shot - I like the way the car is picked out by the lights of the (obviously very close) car behind.

Great shots. I love the last one, it feels like he's just about to pass the ball right out of the frame
