Vivitar 100 2,8 ka as good as kiron 105 2,8 ka?
The focus in kiron 105 is better? I doubt it, As I said .. they are basically the same lens.

How to clean some dots of dust inside the focus screen
Dust on the focus screen won't effect your images so unless they're really annoying you I'd suggest leaving them. If you must clean it then I'd suggest first trying to blow the dust out using a Rocket Blower; if that doesn't work you can remove the screen but be very very careful not to touch it as ...

How to clean some dots of dust inside the focus screen
I have been in this position before and it's very annoying but try and leave it alone as you create more hassle than its worth. Like hefty says i does not have any effect on you images:wink:

Camera stuck in autofocus, switch problem
Hi, I wonder if anyone can help. I have recently purchased a used K100 Super which worked perfectly when I bought it. Since then a problem has occurred with the AF/MF focus switch which is stuck in the Manual position, but the camera working in autofocus. I have tried removing lenses, turning camera...

Camera stuck in autofocus, switch problem
It sounds to that the switch is physically stuck. It operates the autofocus drive pin which is between 4 and 5 o'clock on the lens mount. In MF mode the pin is retracted. It might worth seeing if you can gently push it back in.

Camera stuck in autofocus, switch problem
You may well find that it will cost more to repair than the cost of the camera! You might want to get a quote from an independent first (see ). The link is, as gartmore states, mechanical. Did you bang the pin at some point? You may well find that it will cost more to repair than the cost of t...

Split raw conversion advice
Here's my attempt at a more natural looking effect: I made the original shot the top layer, and made a duplicate layer of it which I turned off. I then traced around the trees with a feathered selection and hit delete to reveal the dark version underneath. Then I switched the duplica...

First Manual Lens
Ok I have just brought my First manual lens off JonSchick. A Pentax SMC-K 135 f2.5. And I must say I wish my new lenses were as well made as this thing! Any ways Ive taken it out this evening and there aint nothing to shoot so I grabbed The landlords dog (whos rather shy) and took a few snaps. ...

First Manual Lens
K lenses can only be used in M mode using the green button to stop down. In menu set permit use of aperture ring to yes. If you use it in AV mode it won't stop down, no matter what aperture value you set . Looking at the shallow DOF I think that's the problem. It just took the pictures wide open. ...

First Manual Lens
Ahhhh I didnt know about the green button. Ile try again tomorow. Thanks Martin! Oh I forgot to mention I did have the arpeture ring enabled and set to manual focus. (which I assume makes no odds to the weighting? i.e. spot, centre, or the otherone (matrix is it?) Do these setting still mater i...

tamron mirror lens 500mm
Absolutely worth persevering with - one of the best mirror lenses ever made. I'm surprised the camera is recording any f number at all, as when I used mine the camera had no clue what aperture it was using (Exif = f--) - but I was using an old Tamron adaptall mount, not the PK-A version (if you...

tamron mirror lens 500mm
Hi thoramay Try using Av but dialling in some exposure compensation (say -2 stops) and see what happens. The shutter speed should vary with the light level. It will be easier to use this on a tripod and focusing may take some getting used to. It's not an easy lens to use, so you may just need ...

tamron mirror lens 500mm
Not bad at all. The DOF is quite restricted at such close quarters, but you've got the exposure right. It will be very interesting to see the outdoor shot tomorrow. Did you find it easy or difficult to focus?

tamron mirror lens 500mm
Where did you focus? Looks to me as if it may be slightly near focussed as the right side of the picture and the hands are sharp and the left side is less so.

tamron mirror lens 500mm
sitting in my chair contemplating how and why I was not getting to grips with this lens and pointed it at several objects in the room. This pic really surprised me. Took it at an angle to the face hence the far side not so much in focus which posed the question of how much depth of field I should ...
