Is there a vertical image on the site somewhere that is displaying horizontal? I'm asking as I can't see one affected by this.

GPS is pretty power hungry so only turn it on when it is useful to do so. Smartphones are no different.

However, they do say 'More on the way'. Where from? Perhaps they've discovered a secret cache.

Yes, it does seem VERY expensive. Well it is that cut price online retailer, is it not?!

They discussed this at the other place: link
May or may not help but a few more ideas about it.

In fairness perhaps I should say I do have Elements 11 installed and find several of its features useful. Its Panorama editor works very well joining multiple exposures seamlessly (better than anything else I've tried.) It's Magic Extractor is good for cutting sections to create layers for graduating or replacing skies. However its raw converter never comes up with an ideally balanced image, sometimes they are way off with the camera default being far superior (other RAW converters seem to be better.) It's also a nuisance that it only allows working in 8 bit for some of its features. I tried the giveaway old version of the full Photoshop but didn't feel I required many of its extra features and it was taking up far too much valuable space on my SSD so it didn't stay long.
My current favourite alternative is EasyHDR3 which does more than just HDR conversions. Once an image is loaded it suggests its ideal representation of the photo along with a number of alternatives. I usually agree with its default. It's similar to Photomatix but the images aren't as extreme and offers more processing options. Very reasonably priced too.
As to Lightroom, I've tried that too but cannot get along with its image importing system. Once its imported a photo it doesn't seem to like opening it again. And I don't want to 'load' all the images in a folder, I just want to open the image I wish to work with. I found it a very frustrating method of working. Certainly not worth 10p a month to me, let alone £10 ! I wouldn't even let them pay me £10 a month to have it installed.
Then there's all that 'phoning home' it does all the time. No thanks.

and the A* weighs in at under a kg. Can't really think why the extra half stop makes the Mitakon so much heavier.

The lens they've pictured is a pre-production prototype so until the production lenses appear its all supposition. So maybe AP and others got it wrong, maybe they haven't. Time will tell. Better start saving just in case! However, if you check the ordering page it's just the three mounts though: http://www.zyoptics.net/product/pre-order-mitakon-speedmaster-135mm-f1-4/ (no Pentax.)

If you check the sample photos on DPR I can't see anyhing special that couldn't be done with a more modest lens. https://www.dpreview.com/sample-galleries/8958190061/mitakon-speedmaster-135mm-f...

Canikonony mounts only, no PK. Production run just 100 lenses. (And 3kg = 6.6lbs.)

If you feel bad about it we do have a current Pentax lens that is dearer: https://www.pentaxforums.com/lensreviews/hd-pentax-da-645-28-45mm-f45-ed-aw-sr.h...
Also the Pentax DA 560mm isn't far behind.

Take one of these next time.
