Hi !

Here some shots from today with my polarizer.
It's linear, not circolar.
Payed 15 used from ebay ( http://www.ebay.it/itm/300880811237#ht_1592wt_1397 )
This work fine with NEX because this camera hasn't pentaprism, so the sensor don't go in mistake.

Location: Salerno - Italy

f11 / f16

Hi IAZA !

I compared with scene without filter.
There are differences about clouds and sea.
But You think that This was my 1st test, In the next days I'll make a specific test.

Pasquale

Beyond a certain amount of polarization a polarizer filter just increase overalll light blocking, as a ND filter with no further polarization. The seconbd photo, at the harbour shows this and some color cast which is supposed not to be found in a good quality polar filter as B+W, only in ones that the warming or cooling efect is expected. I would like to see that scene withou the filter to compare but, now it's not possible.
I like very much the composition of every shot. And surprisingly, if i remember well the Mediterranean water was deep blue, and you show me that it can be also green!

Hi,

this morning I had best condition to test my filter.
There is a concrete difference because the sun was at my left (2 hours after the sunrise).

Here results:

Distagon 25mm + Linear Polarizer

This is a nice 2-samples. I see i very small color cast toward blue with the LP filter, which is absolutely normal for this kind of filter, the shot with is a little bit underexposed compared to the photo without it - i look at the shadows of both photos to remark this. I like both. I saw also how good is the polar to "cross" the haze comparing the mountain in both shots - is it a volcano? - at the background.
Ths lens is superb, i must try one like yours, asap,

Wonderful photos!

I think PL interferes with auto-focus -- I use PL on 5D with pentaprism no problem. Wink

Very nice pictures of Salerno coast,which I like as well ! Very Happy


Distagon 25/2.8 C/Y is my most frequently used travel lens.Not as good as the 28/2.8 Distagon C/Y,but nearly 10 degrees extra fov makes it more versatile.I don't however use filters at all.A few recent pics from holidays:
