No mention of which Windows versions it is compatible with and which it isn't.
I put apps on my phone, but PCs other than Win10 don't call programs apps. So guess it won't work on Win7.
Some basic get you started instruction might be useful too.
Why do some programmers forget the basics?!

Hi! Which pentax m measures the timing with full open aperture ? So the viewfinder doesnt get darker when focusing? Thanks!
A fully manual lens at full open aperture is allowing as much light in as possible, so it won't get darker when focussing. If you can say which camera and lens you're using it will help others to be able to help you get it sorted out. Otherwise it's all a bit of guesswork and you might be given an inappropriate answer!

I bought a Sigma 24-60 f2.8 from a forum member. That's full frame and pre-dates their 24-70 and it isn't too bad at all. Just look at its ratings at the US forum https://www.pentaxforums.com/userreviews/sigma-24-60mm-f2-8-ex-dg.html compared to the 24-70 https://www.pentaxforums.com/userreviews/sigma-24-70mm-f2-8-ex-dg-macro.html
It's pretty light and compact too.

They can't do that if it wasn't designed for FF. OK as a DIY though.

Whether it's true or folk-lore I wouldn't like to say but it has been stated on many occasions that the 60-250 lens design is officially rated as "designed for FF" by Pentax patent US7489452.

Here's a link to the patent: http://www.freepatentsonline.com/7489452.pdf but it would be a braver soul than me to wade through that and find the reference!

IMO Pentax should just remove the baffle on the DA* 60-250mm f4 and update the focus motor. One of the best lenses Pentax have made, compact and much better focal length.
Agreed.

What you want is the Pentax new D-FA* Platinum Series 10mm-150mm f2.0 (a prototype I've been testing for them for a year or so now), it has a 49mm non rotating filter ring, weighs 232gm and is 84mm in length and targeted at a RRP of £249. I find it covers most needs - but until it's released you'll have to make do with one of the other suggestions
How much will the f1.4 version be?

How do you get a 70-200mm out of a 70-210mm????? ..... Cut 5mm off each end

It's the other way round. You stick 10mm on the end; requires an optical adhesive. The Pentax version does away with that so the glue isn't required. Did John miss that requirement out in his review?

Late update, the extra length can be achieved with a variety of filter options, eg UV, ND, polarizer etc. but the combined total extra musn't exceed 10mm.

Changing the subject slightly, one other classic 3D stereo promotion was by Weetabix who put paired sets of images in their cereal packs. You had to purchase the bright red folding viewer (for half a crown I seem to recall). For a freebe they were fantastic quality.
Yes, I remember those too.
There's photos of the viewer and image pairs on Brian May's site here:

Apparent;y the viewer was actually just 1/6 (that's 7½p converted.)

There's an amazing number of image cards for sale on eBay and even a viewer:
