Close up filters, continuation of old thread

I was wondering if it is possible to get a close up filter to attach to my Pentax 100mm macro lens to get shots where usually a 50mm Macro would be most suitable. And also if this would be something worthwhile considering or its just a waste of time and quality wouldn't be good.

Do such things exist that would be suitable for 100mm macro lens? And what are they like?

I found this thread from Mattmatic where there was a brief discussion about it, but as it was from 2003 I was wondering if things have progressed further, besides Matthew asks here for a close up filter for a non macro lens to achieve what a 100mm macro does.

Any advice or suggestion would be greatly appreciated. Just wanted to have a feel about it.

Thank you

Amin

I have a Sigma 58mm achromatic macro filter and some step down rings so can try it on my DFA 100mm macro later if you want Amin.

Mike, that would be really excellent . If you could try it when you can and let us know some results it would be greatly appreciated.

Thanks Mike

PS any more prison trips scheduled for this month to visit your famous friend? . Dont forget your camera so we can see some more great shots of inside the prison life

Like they would let me take a DSLR and lens into a prison visit

They did when you went to visit Tyrese Darnell .

Amin, if I understand it correctly you want to use a close up filter on your macro lens so that you would get a even more close up photos right?

You could use your Pentax 1.7 tc, it would increase your macro from 1:1 to 1:1.7
You can also reverese mount your 50mm lens, they have both a 49mm filter thread I believe, you will get 1:2 then and if you also use your TC that would be 1:3.4
If you want to go further buy a M 28mm on ebay, they are quite cheap. You will get 1:3.6 reversed on the 100mm and with TC that would be 1:6, I believe that would be enough 6 times magnification or not?

That's an idea, I haven't tried the 1.7xTC on the 100mm macro lens. Will try that. As for reversing the lens I tried some time ago, got even the reversing rings and the coupling ones, but its just too bothersome and tricky. Didn't bother to try again.

But now you saying about the TC I think that might even work, going to try it

okay good luck with you TC, I've a 2x TC and that one works fine with the 100mm.

btw I said reversing but I meant stacking, so reverse mounting your lens on top of the macro lens. The reverse lens acts like an high quality close-up filter so it's a budget solution.
But I believe that your TC will do the job or was you planning for something extreme?

No, nothing extreme, just experimenting , its just my boring mind trying to find ways of entertaining
will have a go and drop you a few images and see how it goes

Okay do that Amin, it's always interesting to see what you come up with

I've a portait course tonight with a model so, if I'm happy with some or wont to learn I will post them.

Surely extension tubes will achieve what you want Amin.
