Cir-PL and UV filter give vignetting on 18mm D70s Kit lens.

[Artosoft]

Hi,

I found that if you put Vitacom Circular-Polarizer (67mm) on top of Hoya SMC UV (67mm), it will give vignetting on 18mm to about 30mm (on 18-70mm f3.5-4.5 D70s Kit lens).

I haven't try to remove the Hoya SMC UV, since I don't like to expose the front lens even for a few seconds. But, I suspect is the Vitacom Cir-Pol will still give vignetting from 18mm to 24mm due to it's ring's depth.

I can "tarik" a bit to use both filter combination only from 30mm to 70mm, but I feel not satisfied because I lost 18 to 30mm.

Anyone know how to solve the problem?

Thank you in advance.
Arto

2 solutions:
1. remove the UV filter and then put on the CP (in other words, don't stack your filters)
2. get a thin CP (eg Nikon Slim II CP)

However, solution 1 is much more practical, simplier and cheaper. There is no harm taking out your UV filter. Just have to be careful doing so.

sometimes i shoot without any filters at all on my kit lens,no problem at all ..

dun worry too much about exposing the front element.

Well if it's a 18-70DX I won't mind shooting without filters... but imagine if it's a 17-35...

code,

Thanks for suggestions.

1. I did mention above that I think it is because the thickness of the Vitacom Cir-PL, even without using UV filter, it will still vignetting on 18mm - 24mm. I haven't try this, but I think it still have a vignetting.
2. Nikon is about $190 (if I am not wrong), while Vitacom is only $39. Price talking here

Anyone have solution like do DIY to the Vitacom filter to reduce it's thickness? I am thinking to remove the thread on the front of Vitacom filter to avoid vignetting.

Thanks!

Get a 77mm nikon CPL II, using it with step up ring.
so next time when u change yr lens to 77mm.. is not so heart pain.
besides the quality is good.

u have to remove the uv filter. otherwise, get a cokin filter system.

That's what I do.

same problem here even i bought new hoya hmc pro1 67mm uv filter. (which is thinner then the hoya uv)

IMO, Vitacon CPL is quite thick.
Used to own a 62mm before and sold it off.
Was told by a Cser that Vitacon is thicker than Hoya CPL but I got no
Hoya to compare last time.

anyone tried the B+W F-Pro MRC UV filter which is slimmer than normal UV filters and then stacking the CP onto it?

can't be done .... no thread to stack another filter.

You even have trouble with lens caps with the B+W slim filters so they are supplied with a slip on cover.
