I use my camera for outdoor wildlife filming and as such is often subjected to great fluctuations in temperature. Recently I have noticed that the coating outer plastic lens of the viewfinder was marking probably due to me having to often wipe it clear of mist with a lens micro cloth. I discussed this with my dealer who agreed that I had used the correct method of cleaning and that it should not have marked so easily. To their credit they fitted a new plastic lens and also fitted a 52mm UV filter over top of it. I was not aware there are threads already there to do so! Posted as a heads up that protector filter can be fitted. I believe the same view finder is used on the FS7 etc

I had this same issue within 6 months of buying the camera, I took it back to Sony and they replaced it, i have been careful ever since.

Not had this issue with my PMW-300 but this is good info! Thanks for posting.

I've put filters in EX3s as they had the same issues. The problem is that the viewfinder lenses are not made of glass they are made from an acrylic composite of some kind and can easily be scratched. They then end up being a bit hazy to look through.

Has anyone noticed that the viewfinder eyepiece fogs up easily if you have your eye up to it?

Andrew

Yes, does seem to fog up easily. hopefully, now that I have a glass filter over the lens, may not happen so easily.

Go to your nearest decent motorcycle shop and ask for some visor anti-fog. Spay and wipe a little of that onto the filter in the viewfinder and it should last a number hours. Such as this one that claims days of fog free:

Fogtech Advanced Anti-Fog Solution - Bottle - REI.com (http://www.rei.com/product/718017/fogtech-advanced-anti-fog-solution-bottle)

Before specialist anti-fog solutions became available we used to just cut up a potato into cubes and put the cubes into a zip lock bag for later use. When the VF started to fog up we used to rub a cube over the glass and then lightly rub with a tissue or soft cloth to remove any excess potato juice and what you ended up with was a VF that was pretty fog resistant for quite a while. The amount of starch in the potato defined how long the VF would remain fog free.

i've always had a worry about a. sweat dripping into the viewfinder and b, moist breath on the various switches on the back of camcorders.

Stop breathing Leslie :)

my wife said i did a few years ago - still hasn't helped ;-)

While you are screwing filters into the viewfinder, don't forget that a diopter lens will offer the same protection and magnify the EVF image at the same time, making focusing easier.

Thanks for reminding me of that Steve, a friend has a several and is calling by next week so will give it a try

I have some Nikon antifog wipes.......meant for lens filters. When I use them on my VF, it stops fogging, but it causes everything to be soft and hazzy, like turning EVF detail down to -99. :-o
