"IF" being the key word. I use filters on all my lenses that take them. I do have a couple of lenses that don't take filters. They are the exception.

As some people say, loss of light, not sharp and other optical deficiencies are there to be seen? So that evidence as well as me only shooting JPEG's and not RAW may explain the lack of sharpness, detail and contrast on my images.

Thinking positively, I have plenty of room to improve!!

Spotted this in a camera dealers in Margaret River yesterday.




Saw it and thought about this thread.

To filter or not to filter, that is the question.

While your arguing your points of view, retailers are selling filters based on cold, hard sales techniques.

Comments appreciated. Haven't had time to do much with any editing yet Barrie. Too many images to sort.

100% pure initiative and an original image. Well exposed and good detail. A sense of enclosure due to the slight curvature of the upper shelving. Lends itself to almost being in a position of entrapment.

Yes, sorry about that, I should have waited nearly three hours for it to be posted on the home page.

There is new firmware on the Japanese site for Pentax digitals inc the 645D. Seems to be for compliance with memory cards. I've alraedy downloaded for my K7.

Worth a look if you do use a filters, for those that don't use filters it won't matter.

Thanks chaps. The 50-135mm works very well with the 1.7 AF. The focus speed is ultra-quick due to the short throw of the TC focus range.

Obviously you need to pull manual focus first and then let the TC snap to final focus.

No doubt that on a K5 it will be even quicker.
