What lens while waiting for the 16-50 da*
Peter, I've used a couple of mf lenses and know exactly what you mean. However if you partially compress the shutter release and focus the lense you will get the red dot and bleep confirmation of a focus fix - at least I do with my K100d. I would like to use a better focus screen in the future but f...

What lens while waiting for the 16-50 da*
The red dot indicates where the multi focus point was chosen and like mattmatic suggests, it is more reliable to use the centre focus only option and then re-compose if using this method. According to the K10D manual, lenses in the A series can only use the centre spot for focussing on the K10D (an...

What lens while waiting for the 16-50 da*
Had an SMC-A 50/1.4 for a while - which was absolutely beautiful to use - but my focus hit-rate was pretty poor I also have a 50/1.4 A and less than perfect eyesight but I've found that the green hexagon in the viewfinder gives me perfect focus about 90% of the time - without this focus confirming f...

Pentax-A 28-80mm 1:3.5-4.5 zoom - different versions.
Just to go back to my original post. I purchased a Pentax-A 35-105mm lens and I have to say it is truly a magnificent piece of engineering. Works well on the K10D, and has a very useful macro setting across the whole range. Thanks for the good advice. /Ian

Pentax-A 28-80mm 1:3.5-4.5 zoom - different versions.
You will find that the 24-50/4A is very similar. However the later 24-50/3.5-4.5 is not in the same league. Kim Just to go back to my original post. I purchased a Pentax-A 35-105mm lens and I have to say it is truly a magnificent piece of engineering. Works well on the K10D, and has a very use...

Pentax-A 28-80mm 1:3.5-4.5 zoom - different versions.
Slightly off topic I know but I did have the 28-80 'F' lens and this didn't have SMC it was back on ebay in days. I had a 35-135mm 'F' and found that to be a quite a reasonable walkabout lens, despite the somewhat garish appearance the 'F' series lens have. Then I bought a Sigma 18-125 and that b...

Frustrated over lack of Telephotos
The Sigma 400/5.6 comes up quite often and is a very good lens. I think so too, especially considering how small and light it is - very usable hand-held in fact. I have a manual focus one (not the APO one) in beautiful condition that is now surplus to requirements (on account of the fact that I hav...

Frustrated over lack of Telephotos
On a dSLR with the crop factor, I would be wary of using a 400. You'd think so, wouldn't you. But unlike the Pentax SMC-A 400mm F5.6, which is optically better but much heavier and not as light to focus, the Sigma is very light to hold, yet not at all flimsy. I've used it handheld quite a bit wi...

Frustrated over lack of Telephotos
That's another reason why I like the 200/2.8A on the 2x adapter so much. It is a much lighter and easier rig to use than the old Vivitar 400. :wink: Kim On a dSLR with the crop factor, I would be wary of using a 400. You'd think so, wouldn't you. But unlike the Pentax SMC-A 400mm F5.6, whi...

Frustrated over lack of Telephotos
The majority of that demand will not be in long telephoto lenses that most amateurs only dream about but rarely buy, so I can understand that this particular area has not been the first priority. The K10D seems to have taken most people by surprise as it has certainly hit the nail on the head and...

Frustrated over lack of Telephotos
Hopefully if some longer lenses are released the second-hand prices on E-Bay might start to drop That's a good point. I'd better get on and sell the ones I'm thinking of sooner rather than later. Here's a list of the stuff I'm thinking of selling. I haven't thought much about prices yet, but it...

anything worthwile here?
Takumars are what Pentax called their best lenses in the screw-mount era. SMC Takumars were the best lenses you could buy from any Japanese manufacturer. If your lens is in good nick, the focus ring will move as smoothly as silk bathed in pure Jersey cream. Even the Limiteds can't compete wit...

New camera bag needed
A LowePro TLZ1 is just about big enough for a K10D + Grip + DA* 16-50mm (I just tried it, I have the non-AW version). This combination completely fills the bag leaving only a small outside pouch for accessories. Anything placed in the inside pocket might damage the camera back. It might interest ...

Pentax SMC 1.7 X AF Adapter
Has anybody tried using a Pentax SMC 1.7 X AF Adapter and an f8 pk mirror lens. I know by rights it shouldn't work but i was wondering how sharp the focus would be if it did work correctly.

Pentax SMC 1.7 X AF Adapter
Thanks for that, but i have to use autofocus these days my eyes are not as good as they used to be i just can't seem to get sharp focus without it. I intend to buy the 1.7 adapter and use the mirror lens as a stop gap until i can get hold of a good 400mm f4 telephoto. John.

Pentax SMC 1.7 X AF Adapter
I am using a k110d. I know about the green focus light, I just find it hard to focus on that and the object i am looking at. As i am mainly photographing wildlife i have to be quick. I think my eyes just can't adapt quick enough to looking close up at the information bar and the target object and v...
