And finally...in our kitchen this morning:
Enough light = Sigma 150-500 fine!

ISO800, K7 Sigma @ 500mm, AF200T Flash, autofocus, PSE9....

All's well that ends well!

Roll on SUMMER & GOOD LIGHT!

PM sent re Olympus Varimagni Finder.

Thanks for the encouragement, folks!

Mike, I've never really grasped the percentages thing with crops, so here's the full-frame, jpeg, straight from the camera of the tufty.

The others are roughly the same rate of crop.

Roger.

With 150-500 on the K7....

All cropped, adjusted & sharpened in PSE9.
Further C&C welcome.

Thanks,

Roger.

Thanks, David.

Sorry to have led off a bit & I certainly didn't mean to appear to be biting the hands that have fed me such help & advice here!

Having slept on it, A PLAN!

Go out into the real world, not "testing", in some decent light & take some pics at f8 & at iso 800. See how I get on.

Meet up with someone I know here who has a 150-500 & a K5 & try my Sigma on his camera & his on mine. Note any differences.Move on, if necessary to SRS.

Calm!

Thanks again, all,

Roger.

Further thanks to all for the pointers to solving my problem(?) with this lens.

I'll try further tests this week when I get time/light to make it worthwhile!

I'm getting a little cheesed-off inasmuch as, given: tripods, monopods, mirror-up/remote release, stopping-down, high shutter speed, "good" light, high contrast subjects, (K7!) high ISO, etc., etc., etc.......

In the real world this lens/my K7 does not yield acceptable image quality!

Mind you, it was only 600 quid, so, what the hell.....!!!!!!!!!!!!!!!!!
(Are we down hearted...?
Too *%%^$""£! right, we're down hearted!)

Thanks for your time & advice, Mike.

I'll ring Chris at SRS tomorrow & see what the procedure is.





Thanks also for the pointer to AF Contrast focus in live view, with the ability to zoom-in to check focus. This sounds very handy for macro!

Thanks again, all.

Roger.

Wonderful pics, Alan!

No.2 for me. Great action capture.

Roger.

As my previous post, but focussed using live view.
(JPEG straight from the camera, no PP.)

Certainly not as easy to focus using l/v, since I always use the OME-35 magnifier when using the viewfinder.

I can't discern any difference.....

Can you, Mike?
Can anyone?
Am I any further on?
Shall I return it to SRS tomorrow?


Roger.

Good set, Bjolester.
Nos. 2 & 3 for me, for the graphic quality of them both.

Roger.
