I have the PD-62 Permaraal adapter in my FZ-15 and have allways an UV filter attached to it. Today I added a flexible lens hood and a polarizer filter and I got vigneting at 35 mm, as you can see below. :shock:

[FZ-15] + [UV Filter] + [lens hood] + [polarizer]

I have never seen that before !!

Have you tried this filter combo with the stock adapter?

Then I took out the UV filter, and left the camera as follow:

[FZ-15] + [lens hood] + [polarizer]

and that is what I got.

No nick, I dont have a 72 mm polarizer!!.

Probably this is the reason Panasonic made that huge adapter, don't you think?

I´m concerned about stacking filters (UV+ND+Polarizer+lenshood)... any suggestion?

This is called mechanical vignetting it is caused by stacking to many items in front of the lens.



First, the adapter must place the accessories as close to the extended lens as possible. The PD62 is the DELRIN adapter and is thicker then the metal adapter, which means the accessories are .5mm father from the front element. The further the accessories are away form the front element the greater the potential.



Secondly, you really should not be stacking filters and if you must, they should be filter, filter lens hood.

See if this order solves your problem.



Thirdly, what style of lens hood do you have, is it fixed or collapsible rubber? Because of the nature of zoom lenses, a fixed hood if it is not wide enough, diameter, and may be marginal in some situations causing vignetting. The 1x position 35mm has the widest field of view as you move to 2x and 3x the zoom is not increased significantly but the field of view changes dramatically. Therefore, the hood if fixed can only accommodate the 35mm lens with a shape of 25mm deep and 88mm wide. This depth is not sufficient for zoom positions above 4x and above which needs 62mm diameter hood and with a 88mm depth. The best and they are not that good collapsible hoods are the Hama and Hoya 3 position with no outside threads.



Possible solutions:

Buy an adapter from me in March, ha; I know you do not want to wait.

Pay many unnecessary dollars for extra thin Hoya HMC filters, when Hoya series B or standard filters are superb.

Buy a PA62, forget the PA62H maybe Peter will give you a trade-in?

Stop stacking filters; keep the UV on all the time except when you use the polarizer.

The Polarizer performs only these functions: cuts glare form glass water, metal and makes very sunny skies a tad bluer. If these situations are not prevalent, keep it off. With your stacking combination you are loosing from –3.5 f stops.

Enough for now you might want to check this site for more vignetting information. http://www.vanwalree.com/optics/vignetting.html#mechanical



Now is return please visit my site and leave favorable comments, that is an order. http://lovelife.smugmug.com/
