Old Lenses on a New Body
If you really want to do manual focus (I do) then get a split prism focus screen. You know, the ones all cameras had before they invented autofocus, and we all got lazy.

Do you not get the focus beep with the old lenses?? No, there's no beep with 'M' lenses.

No, there's no beep with 'M' lenses. Isn't there? I always have the beep turned off, but you do get the green hexagon focus confirmation. It's a useful check, but it's not very quick - I keep going past it, and going backwards and forwards to find it. I have just put a focus screen with split im...

You certainly get the green hexagon focus confirmation. i too have the beep turned off, but i am sure you would get that too. You can even go further and use a manual focus lens in AF-S mode. You will find you cannot release the shutter unless the camera confirms the focus ! None of this is as...

Old Lenses on a New Body
I have recently started to use manual lenses on my K20, I made the mistake of purchasing a kood adaptor which jammed on the camera and I had to cut free with my cutters. No damage was made and I took the forums advise and purchased the genuine Pentax adaptor which fits inside the K mount like a glov...

Thanks Pete for your clarification. I use the Katzeye split focus screen and highly recommend it. Its quite expensive but well worth it, especially with the old Takumar manual focus lenses. Spanner: I have a couple of the Pentax adapters and a couple of generic branded ones. The Pentax versi...

Just thought of another question, will the auto focus work through out the full range of the lens. Ian

I have the Kenko 1.5 on my Tamron 70-300 permanently only problem it hunts a bit trying to focus in poor light but apart from that I am very happy with it, it is fully automatic with all AF lenses. I went looking for a photo you can see it here

It still depends on the light you have and the subject you try to focus on, if it has a lot of contrast it will focus easier but still suspect it will hunt alot. Maybe you can focus first at the widest range and then zoom in, sometimes it helps if the focus is already very close. In bad light I mos...

Hello everyone Reading all the replies in regard to the 1.5x, 1.7x, 2x teleconverters; i'm sort of deciding against purchasing one. I take alot of Birding / action pictures, using my Pentax ISTDL and Pentax-DA 55-300 f4-5.8 lense, and find the lense fishes around for focus when zoomed to the MAX ...

Value for the money
All of the Tamron SP Adaptall lenses, especially the macros, 35-80mm and 70-210mm f3.5. As long as you are happy to manual focus they are cheap as chips and much more satisfying. PK/A mount to go with them is another story though.

philistine, autofocus is handy for most form of photography but not all, atleast not for me. For everything in the studio I prefer manual focus and for the studio zoom isn't an piority either, also with macro manual is often used. Martin was talking about focal length so thats were the zoom come...

Wide angle question/favour
Here are some images that show the kind of edge distortion you'll get (Googled these - with Nikon & Tokina lenses... but you'll get the idea) 1) http://static.photo.net/attachments/bboard/00I/00IM8t-32857184.jpg 2) http://static.photo.net/attachments/bboard/00I/00IM8r-32857084.jpg 3) http://w...

Wide angle question/favour
It seems crop factor, focal length and field-of-view are difficult concepts to explain with words alone. Is there a series of good diagrams on the web to make it all clearer? Here is a document and diagram that I did waaaay back in 2003 ;) http://www.photon.me.uk/matt/cameras/pentax/istd_focal.htm ...

But if you're still confused, Foxy, just concentrate on what a certain focal length provides on your digital camera and forget about ...

Pentax FA 80-320mm f/4.5-5.6 should the Barrel be Wobbly?
I had this lens for while and upgraded to the DA 55-300mm, (thanks to a forum member) Your right about the softness at the long end and the DA is certainly better in this respect. I don't notice about any CA with it (DA 55-300)and to be honest I don't even look for it, its not obvious to me. ...
