Attempt at manual focus etc.
Hi Womble, Greytop & Hardgravity, I agree with the comments regarding focus, I will get a Katz Eye screen at some stage this year. But will also have another go (differant subject) ASAP. Thanks for the comments Regards

Doubtless a different screen will help with manual focus, but there's still no reason why AF confirmation shouldn't enable you to focus manually, and have the camera tell you it's in focus. Using the green confirmation hexagon in the viewfinder works fine for subjects like this. You just need to...

Using the green confirmation hexagon in the viewfinder works fine for subjects like this. You just need to be sure it's using the centre AF point, and, very importantly, not move the camera after you have focus confirmation. I'd forgotten about setting focus point, I have mine on centre all the ti...

Nice to see you back Martin :D In my experience too the focus confirmation is not accurate enough for close up focussing. Split prism screen is the only way to go.

The green hexagon has some latitude to play with. Depending on which camera you use. You will notice you can turn the focus ring for a certain amount, whit out the green hexagon disappearing. The will effect critical focus.(specially with the lens set at wide open) Yes, I'd certainly agree with t...

When using MF lenses the centre focus point is automatic selected. No way it will be set at an other point. :oops: So it is! I'd forgotten that. Why is this the case, do you think? Why shouldn't it be able to use the other AF points, just because MF lens is stuck on the front?

Hi Chris, I think it is plain old fashioned "Old School" thinking by the design dep. Because the focus area of MF was based on the location of the split screen/RF patch in the past. A more likely reason could be: Their is no electronic linkage between original MF lenses and modern Dslr's except...

Just tried it out... the focus point is selectable when using a DA lens (in this case my kit lens) and manual focus but defaults to the centre point with older lenses (in this case an SMC-A 50mm f/1.7). (This was with the K20D, I assume the K10D will be identical.) Best wishes, Kris.

Thanks Kris, I'll guess this makes my thoughts about the lack of electronic linkage between dslr's and old mf lenses correct, as the main reason selecting different focus points is not possible.

As a side note: The more I look at the OP's picture the more I am thinking about the dioptre setting, having to be adjusted. Let's face it. The Op thought the Pull was in focus, at least....that is what his eyes told his brain. Because of the focus point being that close behind the Pull ( sugges...

Seems a likely situation Malo. Sadly the dioptre adjustment for my K20D is as far over as it will go and that is just about OK. I have the FA-1W on my LX which is wonderful. I really must get a Katz-eye for my K20D. I have been thinking about it for ages but haven't bitten the bullet yet. I a...

Kris, wouldn't be a slightly cheaper and more versatile solution, for on your k20D ?

Attempt at manual focus etc.
The other problem I run into (especially in low light or with poor contrast) is that the camera doesn't always give focus confirmation. I know this as I've gone through "in focus" and out the other side without even a flicker! The only snag with the Katz Eye screens is the price, and the fact tha...

There is no electronic linkage between original MF lenses and modern Dslr's except the contacts who give the aperture info. ( Pentax A lenses) Sure... no disagreement there. So how could there be communication between the movement of the focus ring and the camera electronics ?? How is that rele...

I am Noooooo...expert either Chris. But if it is possibles to select different focus points with DA lenses, when using them manual focus, I suspect that the way internal lens elements move while manually focussing there is some sort of communication necessary to communicate with the AF system. Why ...

OK, here's my two bob's worth. I've just acquired an A 50 1.7 (took 5 days to get from Texas to Australia. Not bad, eh?), and I've been experimenting with it, as you do. Try opening it right up (f1.7) and placing the subject (a person's face) a metre or two from the wall. Now use the focus tips the ...

Can you tell I got a Raynox recently?
Haha okay I'll get back to you on that one ;)

Sigma 105mm Macro Photos
Went to the garden center in Alhaurin de la Torre this morning, Took the K7 and the 105 macro, all shots were hand held at 800 iso because the light was bad, I love this lens but it is hard work, took more shots out of focus but here is a few that were OK, C&C welcome. Jack.
