A very slight one. It is like green button metering but the shutter fires, if that makes sense.

Yes.

With older presets in Av mode with "use aperture ring" enabled it works just like before except you don't see the shutter speed, just the word Auto. I haven't tried it with "use aperture ring" disabled to see what happens. I'll have a look next time I am out using it.

Yes, but the metering is more accurate than I have experienced before. I always found that "green button" metering was OK wide open but got progressively worse as you stopped down. Now it seems fine.

Hope that helps.

For anyone sitting on the fence about the K-3iii, don't. It's great and that is not just because I am a Pentax fan boy. It is an incredibly solid, well built, and well-designed camera. There are a few things I find mildly annoying, but only because muscle memory has me pushing the wrong button occasionally and I'll get over that.

Now we need someone with the 2000mm mirror lens to show us what that can do...

Lovely. K.

I think the tiny bit of nose really makes it. Super photo.

Thanks all. It makes an interesting contrast to the same scene shot on FPP Let it snow which made PoW a little while ago.

K.

I realise now why. Av mode now works with M and K series lenses by stopping down as you take the photo. Obviously, as the camera has no idea what the aperture is, it cannot tell you the shutter speed in advance. This is a great improvement for K and M series lenses with automatic apertures, but less convenient for preset lenses.

High ISO images are much cleaner. 6,400 easily usable and that is as high as I tried. Much easier to focus manual lenses through the viewfinder (I often rely on live-view for MF lenses). Some quirks, such as the slightly annoying issue with shutter speed indication when using Av and preset lenses (there may be a setting for that). Exposure is pretty spot on. Recovery of burnt out highlights pretty good (on the last one no detail was visible on the sunlit wall when I first looked at it). It'll take me a little while to get all the settings the way I like them, but so far a big thumbs-up.

Just posted some images in the photos section. So far, pretty impressed. The only thing I dislike (which I might be able to change in the settings) is that when I am using a preset lens (like my shift lens or the Takumars) in Av mode, the screen just says "Auto", it doesn't tell you want shutter speed it is using. Otherwise, the viewfinder is wonderful. I especially like the dual levels in the viewfinder.

Having had a K10D, the K20D and the K-3 were pretty straightforward to master. This beast is a bit different and although I can mostly work out how to get it to do what I want, there is a lot of scrolling through menus at the moment.

Went for a short walk this afternoon after I finished editing a paper and took the K-3iii and a selection of lenses.

I emailed Adam at PF and asked him if it would be possible to get it from SRS. As you say, I feel much happier having it from a good UK retailer.
