Oh well. Try this one then:

Just want to point out that your thread title states the lens focal length is 35mm but the photo shows a 28mm one.
Be it a 35mm or 28mm it would work on the K-1 in manual metering mode with the green button. I suppose as to how well would depend on the eyes of the beholder!

The K-3 is a great camera and now a good companion to the K-1. As the button layout and menus are so similar it is pretty simple to swap between them without getting overly confused!
Mine certainly hasn't been overly used as really I've got too many cameras now, what with those and several Q's, an MX-1, a K-m and a K-5 and even a K-01 (not to forget a Theta as well) At least several have been moved on along the way (a K100 and a GX20 and dare I say an EOS300D.) So none get the chance to become worn out!
Regarding servicing a perfectly performing camera, I'd go along the lines of if it isn't broken don't fix it in case it comes back worse than when it went in. If it has issues or has been really heavily used those are other matters that may make it worthwhile but I'd probably just get another new one (or use another I've already got!)
Hope you have a great journey.

I'd at least take a spare card or two in case those Grixx play up again. Even if they're normal SDs you can sort out the filing of the photos when you get home.

FWIW, this is one of the photos I took this morning to test the card. Glad I had the camera out!

Just to say that with my 128Gb micro Sandisk in the K-3 taking raw files everything seems normal (except the number of shots to go which is well over 2000) so no complaints.
Look out for that offer in case it comes round again as £25 was a really good price for a decent 128Gb card.

Would an adaptor like this work with the tablet?

If you're not happy with something purchased by mail order you have the right to return it. I'd do that and ask them to swap for another brand. I think Sandisk should be OK. Can't see SD cards being repairable.

What speed are the Grixx cards? My Sandisk is class 10 80MB/s 533X so much the same as its larger cousins. (I'm wondering if the K-3 can't write to your cards fast enough.)

I'll try the Sandisk tomorrow but can't believe they'll be a problem with it (but if there is I guess it would be useful to know!)

Can you read normal SD cards in your tablet? If so could be another option.

They've recently been doing Sandisk micro SDXC Ultra 128Gb's for £25. I bought one but haven't tried it yet. Oddly, no sooner had the card arrived they wanted me to review it. Perhaps I had better try it in case it is like those Grixx ones.
I get somewhat annoyed being asked to review something the moment you receive it. I reply to the effect 'ask me in a couple of months' - they never do.

Are you going to offer a repair service for broken K-30's Algi? It might be quite profitable.
