25mins could be file size limit, final production models may be able to create a second file with no gap.

We''l have to wait and see. Looks like what you have been waiting for Don.

Dave,

That is only your first problem. The shift in colour of TN screens means they are rather poor unless viewed from directly in front.

Secondly, laptop TN panels only have about 50% of the colour reproduction of sRGB and even less of AdobeRGB.

They can be calibrated to give a perceptive representation of colours and contrast.

Sadly few laptops incorporate IPS or SPVA panels as they are more expensive.

If you have the space and can afford it an LG eIPS display will be much better out of the box than a laptop screen will ever get calibrated.

We have 2 eIPS screens both of which required minimal correction and provide 100% sRGB coverage, which is what the printing labs we use work to.

I'd take it off your hands but my wife won't let me. If it were a few months down the line then the story would be different

Hmm, that is unusual. Any such fault with other lenses? Perhaps it isn't recognising the Sigma correctly. Is it locked in place correctly?

There are several options for AF behaviour on the K-r.

Centre Only
Manually Select
Automatic 5-point
Automatic 11-point

It will focus on the most prevalent phase/contrast difference. If you want to make sure all AF points are working, just set it to manual and focus on ha hard line, change in contrast with each point. The focus points will only flash up when it is the one being used for that scene and confirms focus.

The K-5 has moving parts which need to operate in live view.

The mirror actuator needs to keep the mirror up, that makes a little noise. The SR mechanism has to move the sensor to keep it steady, that also makes some noise.

Noise in live-view is normal as far as I can tell.

AFAIK the K55 1:1.8 is based on the Tak 55mm 1:1.8. I really wish I had an M42 adapter to use my Tak 55 on my K-5.

Well, I'd definitely have to say as an all rounder the DA*50-135 is something special.

Looking for a lens for my dad and this might work. Problem is it isn't his birthday yet...

Not sure I could buy one and wait. If you still have one to spare in a month or two then I'd definitely be interested. Unless I can scrape something together.

Because then you get the DoF of a 52mm F1.5ish.

I'd want at least an f/1.4 DA* prime in the 28-35mm range. f/1 is just asking for trouble at a great cost.
