Cheap Macro Lens
If you have a 50mm 1:1.7 lens or similar, buy a reversing ring and try it. You'll be amazed. Or, Stack two lenses together. Something like a 200mm (zoom will do) with a 50mm reversed onto it gives about 4:1 magnification. You'll need a stacking ring. It has two male threads to screw into the ...

Hi PentaxBabe, Cheeper ways of doing macro are:- extension tubes - see the shop on this site for cheep manual extension tubes Basicaly a tube which moves the lens away from the camera allowing the lens to focus closer. The longer the tube the greater the magnification. But unless you buy exp...

Sigma 24-70mm F2.8 IF EX HSM
Search for this elsewhere on PU? or is it Steve's forum? Its come up before. This is the new HSM version. I tried the earlier non HSM AF 24-70mm version. I ended up buying an almost identical but 28-70mm DG EX version with 77mm filter size. The above has an 82mm filter. I mention the filter size bec...

Macro lenses: Sigma 105 vs Pentax 100?
Same thoughts as the above about quick-shift. I've the AF only on the AF button, so i press that to focus and move the focus from macro to normal (save sore arms) if it overshoots simply stop and bring it close and focus again. most of the time it catch focus in that case. I never really miss a li...

Lens Price Increases!
So all British goods sold in Japan have been reduced by 27%.... I somehow doubt it But you don't know. That's not a fact. Don't forget that not all prices of Japanese sourced goods have gone up yet anyway. It takes time for price rises to filter through and those who want to sell will keep pri...

Mirror lens
Not neccessarily fixed at f8. The 400-600 was f8/f12 and I remember trying a non-Pentax lens which did have "aperture" control. Not too sure if it really did change teh aperture or switched in a ND filter. The 400-600 was supplied with several small coloured and ND flters which I have used occ...

You are right, much more expensive, they are a quarter the cost of a DA 12-24! So is it better to buy the 77mm + step up rings? Or do I risk vignetting when I use it with the 17-70? Honestly €125 is not a small amount, so the quality should be very good! As to the HOya, so you advise against ...

the step up run are quite slim and you go from 77mm to 72mm so don't think it's a problem but you do need I believe a slim filter for the 12-24. Cokin use an holder with square filter and the pol is round so that you can turn it in the holder. Those you show me (hoya) are screw in filters. The ...

A point about the step-up rings, you will struggle to fit them inside the flare hood. I bought a 77mm Kood CPL, quite a bit cheaper than the entry level Hoya and would appear better quality too. As for ND's and Grad's, a square filter system is the way to go.

About filters system
For landscapes a square filter system is the best option, you can easely use more filters and with GND you can move the transsiction so that it fits your image nicely. With screw-in filters for example it's always fixed at one point most of the time in the middle. If you're simply going to shoot...

Thank you for your help and sorry for the delay... the game is complicated, I still have some questions:) to sum up, everyone suggests a square system for ND filters, possibly Z-pro. The difference in price between Z-pro and P is huge. Z pro: kit (holder+ gnd2,nd4,nd8) about £135 single GN...

I got my Z-PRO set (holder gnd2, gnd4, gnd8 ) for €60... i might ask them if they ship to the uk. GND filters are great for landscapes. most of the time, you're sky is to bright on photos and with a GND filter you darken only the sky. I use GND filters a lot when doing landscapes. That's w...

The cokin make a wide angle filter holder for the P range, which is the one I use on the 12-24. Providing you have this attached directly to the front of the lens (i.e no screw in filters first) then you do not get any vignetting, but you are limited to the use of just one filter. So you could not s...

Thank you that is very very helpful!! I think I will get those, especially if both of you are using that system on the 12-24. Just a curiosity, the difference in price between the P and Zpro filters. Is due only to dimensions or to the quality? While I could go for the screw-in CPL or even Cok...

Sorry Hefty the Z-pro use better quality filters out from the Pro range, the Z-pro and X-pro use the same glass but difference size. With the P filter you get more colour cast and the likes. ND filters are there to increase the shutterspeed but somethimes you can easily use an higher f/number to...
