The main Q1 (?) body was all metal. Had quite a high spec too. But a daft price.

I bought it used for not a lot although I cannot remember how much exactly.

I started in photography in late 2006 getting ready to document an overseas posting. With my budget I was looking at three cameras:

1. Canon 350XT/REBEL
2. Nikon D80
3. Sony A100

I went with the Sony, why

a. decent camera, plus or minus a bit here and there but overall about the same as its competitors.
b. the Minolta bit - immediate access to a deep well of reasonably priced good quality lens and it was a bit of a left field choice outside the Canon, Nikon duopoly.
c. the Sony bit - I believed the future of photography was increasingly electronic as an electronics company with incredibly deep sensor and processor skills Sony would end up as a leader and jumping on early seemed fun (and it was a left field choice outside the Canon, Nikon duopoly).
We are all going to die but at least we can go down swinging

Found a few Pentax Q bodies on eBay - varying price. Couple doing the wrong thing (for the seller's wallet) and bundling with a bunch of lenses.

Seems like the '50mm' isn't so easy to find. Plenty of toy/fish.

eBay pro tip - always, always, list things in single lots.

True, but hard to do. You will have to underexpose at 1600 (which will give you darkness in the viewfinder) to be able to raise the exposure to an 6400 equivalent. If you expose correctly at 1600, raising to ISO6400 equivalent will give you big blow-outs. So the ISO adjustment is to allow use of electronic viewfinders.

BTW. Great how this thread has developed into ISO and Pentax Q musings

How to keep viewfinder bright:

Live View Display -> Setting EFfect Off

By default the switch for this setting is the Trashcan/C4 key.

I've used this option to great effect for studio shooting. I'm in a dimly lit room (want not very much 'ambient' light) but I'm shooting at sync speed and for the studio light. So, VF/EVF is pretty much not doing a lot!

But I've found with the A7II default that it will brighten for the LCD during focus for a second (and yes the horrible focus assist beam that all manufacturers continue to install is set to OFF). Found that to be quite smart.

Also, on the street I have my cameras set to 'no image review' (I don't look at photos in the field very often). But in the studio it is nice to see a quite 5s view of the frame.

Thank you for the tip ... I hadn't considered that I can put that into one of my C buttons. There was me thinking I had two too many C buttons, I'll now have three of them in use!

And so we learn every day. Never thought of this possibility, never saw the need.

Not sure what the value is in these (or the early Nex) any longer, other than playing with them for fun.
My phone camera has a much better spec (20Mp with Zeiss lens, OSS and 4k video) and manual controls via a touch-screen menu that's hugely easier to use than the Nex.

The Pentax Q bodies are about £100.
While I use my (new to me 01-Jan) iPhone I prefer holding a camera for some shots.
I don't deny that the iPhone (other smartphones are available) are super tools the experience is a little different. As are the controls.
