A couple of lenses I have queries about!
The two Pentax lenses are up to the highest standards. The Vivitar wide angle is not so well made, but it is a pretty good lens nonetheless. The filters don't seem to match the lens quality, so I'd be tempted to unscrew those and try the lenses without them. The lens hood is very useful at eli...

So called 'close-up' filters are usually of poor quality. A decent set of extension tubes would be my recommendation. If you can find a set that has all electrical contacts and preserves AF, though it's not really necessary for macro work, then go for those. With extension tubes you get no loss ...

But you have to be careful as some extension tubes have no aperture control which can make focussing very difficult and will give you no control over DOF.

close-uplens filter or macro extension tube
Pentax made a couple of good close-up lenses (filters if you like!) and others from major manufacturers like Hoya, B+W, Heliopan, etc. should also be fine. The humble close up lens can be useful as it is (relatively) cheap, needs no change in exposure, retains all the auto functions and, because ...

A cheap 50mm manual and extension tubes from Hong Kong or whatever will give you a "dedicated" macro for little money.

Remember that tubes without electrical contacts will not allow your current lenses to be stopped down. You'll need a lens with an aperture ring! Good excuse to buy a 50mm MF lens...

The alternative is to use a 2x converter, which will turn a 50mm f2 lens, for example, into a 100mm f4 macro lens. Not the same quality, but at least you would see if that lens spec met your needs. The refinement of this is to use a 2x Macro converter, which is specifically designed for the purpo...

Glad it's readable Jamal :) Going a bit off topic but when can you put the definition MACRO behind a lens name? Are there any rules or standards for that?

close-uplens filter or macro extension tube
A bit of a "tweak" to that info, in that Macro lenses are either 1:2 (SMC Pentax-M 100mm f4 is an example) or. more properly, 1:1 (Smc Pentax-FA 100mm f2.8 is an example). Zooms often go to 1:4 which is not bad, and some approach 1:3, but these are not true macro lenses. They do not have close en...
