And I am sorry but if the 55 - 300s out there need to be stopped down to f11 to be crisp then that model is a dog!
It's sharpest at f/11. One of my examples above is at f/8 and you wouldn't know it from the sharpness difference. One more stop open is as wide as it gets at full zoom.

For the flexibility, and price, I think it performs very well. Also... f/11 doesn't hold me back at all.

but I've figured out what the issue is with the Tok 28-200. It's a 3.5-5.3 lens, but it's not transmitting changes in zoom to the body, so wide open at 200, the body is reading 3.5 when in fact it's 5.3 so to get a true 11, I guess I'll maybe need 8 showing in the viewfinder?
OK had a look in the reviews and it looks like your lens is like an "A" series. And you are using it on "A".
Take it off "A" and set it to the aperture you want on the ring. When set like this the lens still stays open while you are focusing and stops down when you take a shot. Take a selfie and see if it is working correctly.
The other advantage of using it at this setting is that Live view is more effective - it autobrightens so that your target is always bright. It won't do this set to "A"
This should help your focusing.
If you set your camera to Manual and set your own same exposure for all the lenses then any significant variations in exposure (apart from the light changing) will indicate faulty aperture.
And above all don't overexpose - that may be mostly what is wrong with the F 70 - 210.
And by the way my attempts are by no means "scientific". What I am trying to achieve is a practical in the field comparison. The trick to that is to reduce the variables. That is why be in manual mode and aperture on the ring. But hard to get around the lighting variation unless I go inside.
The reason for using the Tak lens caps is to try and give an international standardised target but I suspect not as many people as I thought have one!

Gentlemen - I have a basically brand new Pentax D-BG5 grip for my K-3 that I brought, have used twice and has been in the box ever since. I am planning to bundle it with the K-3 which I will list on TM this weekend, however, if someone here wants it on its own PM me with an offer between now and then.

Having established i don't use grips, I haven't brought one for the K3-III

Cheers

Ross

Funny that Ross. My battery grip never comes off the K-1! I like the added size.

I know right. I thought I would at least use it with my big lenses, but generally the K-3 is in a smaller bag for travelling, and when I am seriously using the big lenses, it is on a tripod, and I don't need the grip. Portrait's/weddings, another use where grips come in handy - I don't really do - very occasional family ones.

So I found I never used it. I thought I was going to use it, or I wouldn't have brought it, as they aren't cheap. But there you go. Experience is a wonderful thing

Looks like the Pentax D-BG5 can take AA batteries as well?
That's an interesting feature in itself if you were travelling and couldn't guarantee a place to charge etc.

Funny how we purchase things but don't necessarily end up using them.
Honestly thougth I'd get more into using a flash than I ever have for example.

Yes, it comes with 2 trays - one for the standard battery, and one for AA's so very useful if travelling

Like the BBQ rotisserie kit I have that's still new in the box. 20 years later.

No, there is a different newer battery grip for that - please see this B&H page
K-1 = D-BG6
K-P = D-BG7
K-3 III = D-BG 8
K-3 = D-BG 5

The pricing structure in USD is interesting.
