These are the sort of posts that must attract the casual passer bye to consider using Pentax cameras. Why buy another brand that does not have these issues when you could by a Pentax body and spend time working out how to get correct exposures with old lenses on various recent bodies.
I have a shelf full of older glass. Do I use it often? No I don't.
For the same reasons that people don't try to get an Intel 286 to run MS Office 2010. Today you can take photographs with Pentax lenses that do meter and work well, tomorrow you may be dead.
Just a point of view. Otherwise, keep up the good R&D.

Fascinating. No Pentax images there, though, is this allowed?48 DSLR's used to capture amazing images.

One could take all the data for each model, and work out the standard deviation as well as the average - and then have some slightly more useful values.
And, if you really want to see the value of that database, look at the figures for the SD9 Sigma - a sample size of 13, of which two appear to be the same camera (and are certainly the same person reporting). I find it hard to believe that two samples should each fail at exactly 65278 actuations in the same pair of hands. Not impossible, just very hard!

Now that was being nice, John.It is interesting, but as the failure rate is based on only one negative result maybe it needs a larger sample.

That makes more sense as I had heard it was closer to 104.8%I did hear that over 80% of statistics are made up anyway.
In a way, statistics are only that and may have no real impact on most people or their activity. Unless your an insurance broker?

The OP wants a full frame yet poo poos most of the options available!!!
If the D700 & D3x's low light are last generation then what is the best low light option for ff??? As I understand one of the reasons to go FF is for the low light capabilities, are you saying that APS -C low light capabilities are now up to ff standard???
If I was to upgrade for anything it would be a D3 alas the £10,000 needed to completely swap over is way out of my budget
Not according to DxO (and no I don't use such data before buying cameras). The sports low light ISO for the K5 is 1162 and 2303 for the D700. The D7000 is up at 1167 which is the same as the K5 for the same sensor. So I'll be keeping my D700 for a few more years.The OP wants a full frame yet poo poos most of the options available!!!

I was at one point too enthusiastic, wanting Pentax to launch a FF but no more. I've had FF for over 2 years and never looked back. If Pentax do ever launch FF, I'll consider it just to use the Ltd's properly.

I did try to word the post correctly. Basically trying to bring to attention that it may not inspire some people to take up the brand.
I have used M series glass on my istD and K10D. I've not had issues with my A series lenses.
