Hi,

I went to a camerashop for a UV filter (just to use as lens protector). He didnt have one in stock, instead he tried to sell me a skylight filter. Is it any good or will it affect/alter the photos in any way ?

cheers

I always thought they were the same thing, different name.

I have both and can't discern any noticable difference.

Steve

No real difference; either will do the job.

Also sometimes labelled as a "Haze" filter too.

Cheers,

Thanks guys. That helps a lot.

gstark, In my earlier posts I had a question about Yashica cs201 flash with D70. I borrowed a DMM. There are ony 2 points on the flash going on camera's shoe. As it charged it showed around 8.8 Volts DC.

Here is a link to an interesting article that has the same shot taken with UV, Skylight and haze filters.

http://www.cs.mtu.edu/~shene/DigiCam/User-Guide/filter/filter-UV.html

I also read an article somewhere on the net recently that talked about skylight filters being most useful in the northern hemisphere - can't remember why - it was part of a much longer article similar to the one above and unfortunately I didn't save the URL.

As it charged, or when it discharged?

As I understand it, you should wait until it's full charged, and then discharge it, measuring the voltage as it discharges. Fortunately, this is an easy task to accomplish, as the act of measuring the voltage across those two points will cause the flash to discharge.

IAC, compare your voltage with that in the list of flashguns (that will tell you the accuracy of your reading, and I believe that someone posted the link for that) and then you need to see if your trigger voltage is within that specified for the D70, which I think someone else has posted here.

Perhaps do a forum search on trigger voltage.

Gary,

Yes I measured the voltage when fully charged -- was 8.5 VDC, did not peak and went straight to 0 after discharge (DMM was on all the time). I took it to a camera store and confirmed it. The guy wanted to to try it on D70, I warned him. He said no worries and then tried it on a D70 and the flash did not work. However it did not fry his D70 either. I just wanted to let you know. It was Yashica cs201 flash.

Ajax,

I think that the trigger voltage on the D70 is 200V (Please somebody check this) and if so, then 8.5 is quite safe.

You say it didn't work when you placed it on the D70; did the ready light go off when you put it on the camera?

200V trigger voltage sounds bit high for D70 IMHO.
Maxwells couldn't answer the question - said that info wasn't published & even if it was the recommend using dedicated flashes anyway .
This site has http://www.botzilla.com/photo/strobeVolts.html has strobe trigger voltages table covering most manufacturers.
Might be of help.

Cheers.

D70 trigger voltage recommended not to exceed 250V. It's in the manual. Nikon's own speedlights trigger at 12V, which is a long way off from max.

Thanx for that. Page 186, down the bottom, for those who might like to ring up Maxwells and tell them about the products that they're supposed to know inside out.
