I have got a K 105mm f2.8 which I want to use as a macro.

I understand the use of closeup lenses like the Raynox, makes the dof very small.

I wonder what effect would

A] Bellows ( http://www.amazon.co.uk/Fotodiox-bellows-Pentax-Digital-Cameras/dp/B003EDWHYC/re...=sr_1_2?ie=UTF8&qid=1317430309&sr=8-2 )

and

B] Extension tubes ( http://www.amazon.co.uk/Extension-Macro-Pentax-Mount-Camera/dp/B003VI2AOW/ref=sr_1_1?ie=UTF8&qid=1317430173&sr=8-1 )

have on

1) Magnification

2) D.o.F

3) how to meter for the shot with the attachments.


Which one would you recommend for handheld macro. I will be using a LED video light for addition lighting when necessary ( http://www.amazon.co.uk/64-LED-Light-Olympus-Panasnic-Camcorders/dp/B003LAAESY/r...=sr_1_3?ie=UTF8&qid=1317430065&sr=8-3 )

I would have loved the K135/2.5, but I am not exactly having a great time with my K50/1.4

But that's more likely to be related to my skill rather than the lens itself. Someone please buy it before my LBA kicks in (again)

I want to make an offer on the K 135mm, but I want to see how I get on with my newly acquired K 50mm first

Thanks for that. This is certainly very interesting.

I wonder why a lot of eBay listing has line wording: "not the inferior takumars"

I beg to differ, the whole point is you have full manual control and the K135 is a superb lens and I think someone is selling one in the classifieds

Yep, sellers should refund/ replace.

I sold an item on Amazon and Hermes (first and last time I used them) damaged it in transit. I refunded the full cost plus return postage.

Oops deleted my question by mistake

My question was the diff between M, A and K lenses with relevance for use on a K5

I want Pentax K50mm 1.2 ...

What's the full description? Does it need an adaptor. I'm presuming it's MF only

I like the leaf one, the one with the Meyer Optik is too distracting

creamy, smooth, non-distracting
