Was sad not all images deserved a comment. I stopped submitting entries following a dearth of comments a while ago. It seems things haven't changed.

In my K-3 I have an 8Gb card in one slot on which I save jpegs and a 32Gb card in the other slot to save raw files. Should one card go bad hopefully the other will be fine (though I haven't, touch wood, have a card go bad.)

Re the earlier comment about using 512Gb cards - Sandisk do make one but gather it costs around £500 - that has to be the dearest card I've ever heard of. Though I remember Jessops selling their own branded 96mb compact flash cards for £132.99 (the packet still sports the price label!)

Re fake cards, I guess these can crop up anywhere but buying from a reputable dealer should avoid such issues (I would hope.) If a dodgy card was obtained from a reputable dealer I would expect them to investigate their source and take appropriate action. If a deal looks too good to be true then be wary.

Thanks for that. As you say its very good, and free. Its map page isn't that dissimilar to the Ephemeris.

There's plenty of UV in sunlight too!

Don't worry until the Governor of Arkansas has personally written to you and all the the other photographers in the w̶o̶r̶l̶d̶ (no, sorry) universe to point out their new law to you!

Do these help Vic?

I didn't think it would be any good this morning, but surprise surprise, the sun broke through!

My efforts:

Not sure what reviews you may have read but user reviews seem to rate it highly, e.g. http://www.bhphotovideo.com/c/product/740381-USA/Pentax_21977_SMC_DA_18_135mm_F_...
The bad reviews reflect its launch price when it did appear poor value compared to other similar lenses (eg Pentax and Tamron 18-250's.) Don't ever remember hearing it described as terrible though. Where did you see that?
re K500, I'd presume it's compatible but have never personally seen one let alone tried one! Sorry about that.

Not really. A 24mm lens will always be 24mm. But as the full frame camera has a larger sensor more of the image circle is recorded. It would be better described as being the equivalent of using an 18mm lens on an APSC camera.
