Hi i am ging down this evening to get the stuffs.
Please help me



I am thinking of using a cheap UV 43mm filter to be used as a adapter ring extension for my CLA-1. So i am going to buy a 43mm UV and circular polariser.

I wonder if at 43mm size, would the Circular polariser cause vigeneting at wide angle of 35mm in c4040z

Is it easy to get 43 mm lens cap and fitlers...?

43mm ones are more expensive.

THanks for all the advise on size4.

But i need to know more importantly, whether the circular poloariser would have vignetting effect on c4040z at wide angle of 35mm

Why not bring your camera down and try it out? If there is vignetting you can see it on the LCD...

Maybe you could stack a few filters, if you have them or borrow them from the shop, to make the equivalent of the polariser's thickness. You'll know then whether there will be vignetting.

found a way to test. Use paper rolled up and slotted into the lens barrel gap. The extension provided by the paper would duplicate the effect of the stacking of polariser. Then you will be able to see if got problem.

looter, thanks.

Really c4040z does not need a spacer. Just a 43mm UV filter would cause the lens to crash. But it is really close. Almost touching. I think if got sand such scratch lens and filter.

hi,

for info, i have tried the 43mm polariser and got a little bit of vignetting. It is so mild that it is just blur corners.

nothing. Never stack with UV. Just CLA-1 without extender.
