that looks very strange!!!


as to the bag, it is very cheap but I'm waiting for the Slingshot 100 price drops down!

Thank you a lot guys, just a clarification because I'm a bit confused.
So are you suggesting me to get a Cokin system: Z pro holder (or Lee) and all filters Cokins Z-Pro.

or a 77mm Hoya CPL pro1?

Will I use CPL, ND and later graduates most likely on 12-24 and 17-70 only, won't I?

Thanks!

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 normal one against the PRO1
On Amazon the cost is one third!
I can't understand the difference with this this?

Thank you for your help

EDIT: is that true that Kenko are "the same filter as Hoya in different package and much cheaper"?

Sorry Stefan, I'm Italian, can't understand what exactly you mean!

are the less expensive themselves or you mean the overall system?

Hi all!

Hoping this is the correct section,
I have got:
- 12-24 diameter 77 mm
- 17-70 diameter 72 mm
- 55-300 diameter 58 mm
- 50 - diameter should be 49mm

I would like to buy a ND and a circular polarizer, which system should I look for, to be able to use the same filter on more lenses (both for handiness and cost?:

1- Cokin system

2- Ken Rockwell's suggestion:"Don't even think about using more than one filter size. It will drive you insane.
Honestly, if you are serious about photography you will eventually wind up buying the bigger filters, so if you start there you won't have to throw away all the smaller ones.
I suggest using step-up rings and bringing all your smaller lenses up to the largest common size. For Nikon and Canon that would be 77mm.
For instance, instead of using 62mm filters on your 20mm f/2.8 AF or 72mm filters on your 28mm f/1.4D AF, just step them up to 77mm and never look back. Do you really want to buy and carry an additional dozen smaller filters instead of just a couple of step up rings?
This saves a lot of fiddling when you are out shooting and trying to swap filters around.
I suggest B+W brand German step up rings because they cost about the same as the crappy Japanese aluminum ones. They don't get stuck and have nice knurling to make them easy to grasp. They cost me about $12 - 20 each here. Big deal.
If you use these stepping rings you probably won't be able to use a standard hood. I never use hoods so I don't worry. Lens coatings have made hoods obsolete for decades, except as prophylaxis (protection). Your hand provides much better shielding against the sun."

-any other ideas?

----------------
I suppose the common use is for wideangle lenses
(even if Ken Rockwell says:"Avoid polarizers on wide-angle lenses You'll get weird effects with a polarizer on any ultra-wide lens. Linear and circular polarizers give the same weird results on skies.
The weird results on ultra-wide lenses are because the polarization of the sky varies from one end of the sky to the other. Polarization of the sky is maximum at 90 degrees from the sun, and none at the sun and 180 degrees from it. This is no issue with a tele lens, however with a super wide you are sweeping such a broad expanse that the polarizing effect will vary greatly across the sky. You often get a dark area in the sky, which usually looks nasty. I rarely use polarizers with ultra wide lenses.
If your polarizer is thick (as many are due to the rotating mount) you may be getting mechanical vignetting in the corners, too".

I knew about the vignetting, but also that effect?

Thank you

Thank you guys, I'll buy this or this and the lenspen

thanks...
I try to do not forget:first rule is not to clean!

Thank you for sharing your experience!

do you mean in the handbaggage or in the other baggage?

Thank you Stefan,
clear as usual!

from 18 to 270 all in one?amazing, but probably with the same (or more) defects

If I'm not wrong Simply EL import from Hong kong as well
