catch in focus
I've been trying to make an AF lens manual so I can use it! :D There must be some well proven techniques for doing that. Dropping it usually works but might not be reversible! What you could do with is... DFA 100mm f2.8 macro. But many of the old manual macros were excellent lenses. Have had a V...

catch in focus
Not sure dropping it would be adviseable in this instance as it's the 'plastic fantastic' Vivitar 100mm! Adding a 12mm manual tube works, but I suspect I might have been better off with an older, manual lens rather than trying to make a modern AF lens manual. I certainly could do with a DFA 10...

No, best not drop it really! You might find only the autofocus works! How about: ? For future readers once the link is no more it's a 'Pentax SMC-M F4 Macro lens - K-Mount - Excellent' John

catch in focus
Thanks John. I saw that, but 50mm is a bit close. Now I have the 100mm I prefer the working distance. Good price though as long as it stays at £25:D

A big decision
K5 - no brainer, an absolute must have ahead of all else ! I wonder just how good the Bigmos or the Bigma would be in comparison to a DA*300 (cropped or with TC), certainly the K5 has the edge in speed but when shooting birds I'm almost always f8 to f5.6 (unless dusk has set in and you still can't d...

1. When you put the AFA x1.7 on any lens it's immediately semi-AF. That is it is manual focus until you are in the vicinity of the range that the AFA covers by itself (it has a tiny focusing motor built-in) then the AFA takes over and snaps into focus. When shooting birds at infinity this means it'...

A big decision
Thanks Frogfish Can you explain thought the first part a little easier for me ;) I dont quite follow you. do you mean you can manually focus first to help the lens and then kick autofocus in at closer range? If the 550mm lens is around 2 grand I am def buying it :)

A big decision
As said above - the K5 will make by FAR the biggest difference to your wildlife photography - I upgraded from a K10D and am now able to take SO many pictures I couldn't do before, as most are in shaded woodland and low light. For two years I've used a Sigma 120-400mm non-os with reasonable result...

Catch in Focus?
I've tried to use the catch in focus prog. but it seems I have to use the shutter each time. (K7). Not tried on the K5 yet. On my old Chinon once it was set up I could press the button and walk away and the camera would roll off a whole roll of film as and when something came into focus. Am I missin...

Catch in Focus?
Have you got the body set to AF? Should work fine with a manual lens, CIF 'on' and the body set to AF. I have a range of manual lenses and they all work fine with it.

Catch in Focus?
tried again body af ,lens mf on switch and that works as the camera sees the change. i can see why i think ,because i have locked the focus on a point so if the release is fully depressed the shutter will fire as it is told to do in the menu c.3 15. afs setting 1 focus priority= shutter can not be r...

Catch in Focus?
I haven't done this with a K5, but I have used it a bit with a Kx and an old Tamron manual 500mm lens, with quite good results. The bit that confuses me is where you say "as you have put something in focus (your point) the shutter releases". If you focus on a point where there is something presen...

Catch in Focus?
I got a bit confused by last night's post too. I would have replied, but wasn't sure what the problem now was as it seemed to be working correctly. If you set the body to AF, CIF to 'on', take everything in the viewfinder out of focus then press the button it shouldn't fire. Keep the button press...

Catch in Focus?
now i am awake. yes it does work as you say, what made me muddled was the phrase in the instructions "set the focus on a point" so i assumed you focused on a point and it was the movement of something coming into the area that triggered the camera. that is how i interpreted the instructions. so if y...

Catch in Focus?
It's probably easiest to imagine something like a hedge, flat on to the camera, say 30 feet away. Defocus the hedge but move the focusing ring to a point closer, say 10 feet away. Now let your model walk into the shot. When he or she reaches the point of focus, the camera will fire, and your mode...
