Reverse reversing ring?
Hi Vic How's your DIY skills? You could drill out a rear end cap with large enough hole saw so that it can then accept (maybe with a little persuasion!) an appropriately sized step-up/step-down ring with a 49mm filter thread. Cheers Mike

See my topic from 2007 . I think you'll have to make one. If you choose the right donor extension tube, you can even have it locking onto the end of the reversed lens. Mine doesn't but it's never been a problem so far. I used a larger filter thread than you need. It might be sensible for you to ...

Reverse reversing ring?
Bit rushed - sorry - is this the one ? Tony That looks to me like a lens to bellows mount, with a V groove rather than the filter thread. If so I've seen the BPM version for sale at £20 (updated price). Mike

I have a reversing ring for a 49mm thread 50mm lens. What I want is the opposite. Instead of the ring being positive K bayonet to positive 49mm thread I want it to be K bayonet female to 49mm female so that I can put it on the end of my reversed lens and fit my Pentax 080 ring flash onto the front. ...

To all who replied with very good suggestions, especially Petes 2007 link. THANKS A LOT. I think I might start looking for some bits and pieces. I already have a spare 49mm filter I can use. I also have some old Chinon lenses I may look at to see if can possibly dismantle and use some of their part...

Reverse reversing ring?
I've just had a thought. When putting an extension tube and a filter ring together why take the filter glass out of its ring? As we use filters on our lenses (most of us) why not leave the filter glass in situ? Looking at various cheap sets of extension tubes am I right in thinking that they have ...

Thanks David. Looking at the various adverts to me it looks like the adaptor has a K male and screw female and the tubes all have male screw and female K therefore any would do the job except that the 2nd. and 3rd. would be longer than the 1st. thus moving the flash further forward from the lens and...

Thinking of picking up a Macro...
I am seriously wondering if I wouldn't just be better off stumping up for the Pentax because the colour and overall look of the results would be similar to my 15/21/40/77 Ltd and 200DA*? Or do the results from the Tamron/Sigma's look Similar as well:?: Just get the Pentax, you've quite a lot of the...

Good luck Paul and if you get it - one tip for you - do not waste money as I did buying a decent UV filter and then spend more money on a CPL - I never take the CPL off unless shooting in very low light - this lens loves a CPL and the UV stays in it's case! Carl

1959 Pentax Auto-Takumar 55mm f/2 -v- Pentax 'A' 50mm f/1.7
The tricky part with all Takumars seems to be finding one which hasn't been meddled with and doesn't have any scratches on the glass. I've been lucky with my 35mm and 135mm (both near perfect with just a few paint rubs), the 55mm f2 had lost its trip pin for the auto stop down function so I had to m...

50mm Lens 1.4
I would go for the Pentax FA50 f1.4 as long as you realise that wide open it's not brilliant. It's OK at 1.4 but gets better (very good) as you stop down to 4 or 5.6. I like the lens & it useful as a short (& fast) telephoto on an APS-C camera. On my K-7 it's equivalent to a 75mm lens on a film cam...

Stefan, I have both of those, they are the two I'm wondering about actually. The filter itself does not look too deep but is deeper than a Pro 1, anyone any experience of these:?:

Hi Jules, the hoya filter I have is 5mm deep - cant test it in the 15mm Lts 'cos my filter is a 52mm thread and the stepping ring wont go on because of the built in hood getting in the way (hence my recent topic question). I've just tried a Kenko filter which is 4mm deep - no vigetting. D...

Ok further experiment - just stacked the the kenko, stepping ring and hoya filter, total depth 13mm and got slight vignetting at the corners, so looks like a 5mm deep filter would be Ok. Hope this helps H

Pentax 15mm Limited and square filter systems
Has anyone tried using a square filter system such as Cokin or Lee on the above lens? I ask as I am wanting to invest in one of these systems (probably Lee if/ when the filters become available). On the 15mm Ltd the lens hood protrudes slightly when retracted and I am worried the filter holder ma...
