Photographing birds by accident
As a rule, if a bird ends up in any photograph I take, it is there by accident rather than by design. I have been wondering, though, whether I should change that and try to take some deliberately. I joined a camera club a few months back and have seen pretty ordinary looking (to me) photos of bird...

Photographing birds by accident
I think it's true what has been said about bird photography not generally being done to be artistic. I started to do it as a hobby when dog walking - when you tend to travel the same route a lot it's good to have something else to do at the same time. There are plenty of challenges and it can be fun...

Photographing birds by accident
Quite possibly depending on the Judge, but regardless of what judges think or what method they use you shouldn't take pictures to please them Yes, I agree with that completely. This birding business is strictly experimental. I tend to take way too many "landscapes" (aka holiday snaps) and need to...

Photographing birds by accident
Ours is just a friendly little meetup group with no prizes but the judges often seem to fall for a quick cute snap of a child Rarely had that from a Judge, comments are usually "its a competent shot and the childs parents must love it" just goes to show how varied judges can be. The closest focus...

Photographing birds by accident
I received the Pentax DA 55-300mm from SRS a couple of hours back - and took a few test photos out of a bedroom window. This is the image taken by the Tamron 400mm (same image as first post in the thread, repeated for convenience), taken at f/11: This is a shot of the same door (around 80...

Photographing birds by accident
Did you buy it for photographing doors? :mrgreen: :wink: Doesn't everyone? Actually, thinking back, I am not really being fair to the Tamron 400mm. The shot with that was through a double glazed window. The others were not. It looks good, but 80m is a bit far... holding the lenses steady be...

Sigma AF 70-200mm f/2.8 EX OS HSM AF
Hello to all. I just received my new Sigma AF 70-200mm f/2.8 EX OS HSM, I'm experiencing it, and notice that the AF is quite fast, but is very confused and does not focus on AF. Here someone has the same lens and can give your opinion about this problem because I have to test the lens for one more...

Sigma AF 70-200mm f/2.8 EX OS HSM AF
I have the same lens for sale on this forum and it focuses fine. Your problem sounds very much like the one I had with my Sigma 50-500mm where it would just "judder" back and forward but not lock focus on anything. It went back for repair and has been fine since.

Sigma AF 70-200mm f/2.8 EX OS HSM AF
At first the problem of lens focus was her turn to both sides and not lock focus in the right spot you wanted to focus on. But then began to focus as it should be, and not focus on failure, and moreover is quite fast. I appreciate your attention on this issue,. Best regards

500 Telephoto advice for K100d.
If you can stretch to about £350 then an older version of the Sigma 150-500 would be a safe choice. You may find the earlier Sigma 170-500 for a little less but I'm not sure how the IQ compares. Even if you do not mind manual focus I cannot think of a quality 500mm that you will find for less. Perha...

500 Telephoto advice for K100d.
Thank you all above for your helpful comments.I have a sort of top spend of about £500. Taking that a bit loosely I have seen Sigma 120-400 & 150-500. I believe in both cases the K100d would not run the Auto focus, and why pay for a bit I cant use? I want the quality of image that will make a Sparro...

Vivitar lens
Hi All, I've been given a Vivitar 28mm 1:2 manual lens from the estate of an old Pentax photographer I once knew. His camera has been given to a relative. The lens is in quite good condition considering its years but, whilst it will fit and operate on my MZ60 it will not even fit my K10D/K5. ...

Vivitar lens
Vivitar made some excellent lenses. The Close Focus variants of the 24mm and 28mm focal are examples. Some of the non-CF lenses too, so long as they were not made past the mid-eighties. Hope my page helps.

Vivitar lens
The following pic is a closeup of what I can see when holding the lens at a slight angle to incident light - not the best (photographically speaking) but it does show the 'spider web' It's off to the tanning salon at the end of the week - I'll report back later. regards Bernard

Viv is back from her holiday on a sunbed and I can't see the slightest improvement. So I think the next tack is to get her stripped and rubbed over with cold cream I'll keep you posted on progress regards Bernard

Opinions needed on Sigma 400mm F5.6 APO A Manual Focus
My repute it is OK but not outstanding. The other Pentax forum has a review of it. I've got the cheaper non-apo version of the same lens, which is usable and better than a bottle-top, but not as good as say the 55-300 cropped to same image size.

Opinions needed on Sigma 400mm F5.6 APO A Manual Focus
Nothing special to be honest, the one you want is the Sigma 400mm f5.6 APO Tele Macro ... best of luck finding one though, I have been looking for ages.
