Close up lenses afford a means for us to try out close up photography at low cost. Stopped down to f11 or f16 results can be very acceptable.

If the bug bites, then eventually a macro lens may be the thing to go for.

That's the whole point of a close up lens. It enables you to move closer. With the CU lens in position though you won't be able to focus very far away.

You will have to get quite close. A set of CU filters usually is a +1, +2 and +4, in combination they can provide any value up to +7.

A +3 on its own should work, maybe you are just not getting close enough.

I would set the camera on MKF, selct the closest point of focus and then just move inwards until the subject is coming into focus. This will give you an idea of the general working distance which you can then hone in on more precisely with the camera on a tripod.

Photography is integral to whatever I'm doing, so I'm making images most days in one way or another.

What I enjoy best is image making with a project in mind. This can be a simple or complex project, but it gives purpose to the exercise. So I can enjoy the process of taking images for putting on eBay and then again a long landscape walk somewhere interesting just as well.

There's not been any particular evidence of a general problem, certainly not one that's been noticed here.

The point about using Pentax lenses is a fair one because Pentax make no guarantee (nor could they) that third party accessories will work properly on any of their cameras.

It's up to Sigma or Tamron or whoever else to ensure products they make work on the items they are intended for use on.

Very good, an interesting lesson in itself.

Welcome to Pentax User!

Lenses...you'll find plenty of vigorous discussion about lenses here!

Not guilty...

The NT are in a much more reasonable mood these days, and even inside properties they usually welcome cameras.

This batch of images is very promising - some i might think of tweaking a little, such as the tonal values in nos. 4 and 6, but they really are splendid. The effort was absolutely worthwhile.

Some great images there.
