Focusing Screens.

Is there an alternative focusing screen preferably with grid lines that I can buy to replace the standard one on my MPP Mark 8 camera?

Thanks for the info Gari, are there no alternative products in the UK?gari wrote:I ordered a satin snow screen that was made for a Shen Hao from Badger graphic. Came from stock so I got it in about 10 days from the US!!
Cost was about 10$ with about a fiver for postage, I think.
No grids but that would be a simple matter to put your own on with a good graphic art propelling pencil, .5-.3 mm ish.

Hello Joanna,Joanna Carter wrote:Keith, IMO the best screen available has to be the Maxwell. It is not just a GG, it is a micro-fresnel and is even better at handling everything from 72mm to tele lenses than the Ebony ones. Unlike Ebony, you only need one screen for most usable focal lengths. What is more, they will put a grid on it, as long as you don't mind it being in imperial measurements due to the American lack of understanding of metric![]()
Bill Maxwell is very personable and eager to please, just don't expect to get away with a cheap phone callThe web site is http://www.mattclara.com/maxwell/index2.html.
Due to the exceptional nature of these screens, they do tend to cost a bit but with the current exchange rate of $1.95, you should be reasonably happy with about $220. Bill did say that he might be able to do free delivery if you mention the UKLFPG but don't assume it; he is only a small company and hasn't much wiggle-room on prices.
I measured the ground glass screen and it measures at 125mmX100mm, I can`t measure the depth exactly, as I don't have a suitable gauge, but is approximately 1.5mm thickness.gari wrote:Hi Keith, the GG is exactly 5.25inx4.25in, the thickness isn't so much of an issue as GG thickness is fairly standard.
Also the springs or clips have a modicum of tolerance due to the flex of either design. Mine was 3mm just for the record.

The Maxwell screen is a GG on one side and the fresnel on the other. With the Ebony, all you need is a cover glass to complete the setup.gari wrote:Although the MPP didn't come with a fresnel, there is no problems getting one with a fresnel if it fits
I am awaiting a second reply as I have asked about the suitability of the HI-LUX Ultra Brilliant Matte 4.7 screen as my universal screen for both Macro and ordinary photographic uses with my lenses ranging from the Schneider 58XL through to the Nikon 300mm/f8. I will post that reply here once received, for your information.Apple wrote:Thanks for the info - it maybe saves me a phone call if I get round to affording a screen (by which time the price will probably have altered.)
It's answered one query - Bill can supply a solution for the Ebony asymmetric markings as I didn't really fancy pencilling my own on to a screen / glass.
I've looked through the one Joanna has on her camera and it is brighter but I'd have to get used to the low "noise" levels - you expect some grain from the ground glass but there is very little texture to the Maxwell screen. I initially tended to think that things weren't sharp as I wasn't seeing any "bite" to the image.

Well, I can tell you that I can easily use anything from my 72XL right up to my 400mm FujinonTThingy wrote:I am awaiting a second reply as I have asked about the suitability of the HI-LUX Ultra Brilliant Matte 4.7 screen as my universal screen for both Macro and ordinary photographic uses with my lenses ranging from the Schneider 58XL through to the Nikon 300mm/f8.

I have both a spare Ebony standard and a W/A fresnel, if you want to do a comparison. All I can say is that it is not only cheaper to buy the Maxwell, it is also much easier than having to change backs whenever you need a longer/shorter lens.Thingy wrote:I think the price is relative. I was originally expecting to pay £315 plus VAT to buy an additional mount plus Ebony's wide-angle screen to use whenever I was doing architectural photography. If I can get away with a single screen mounted in the holder supplied (retaining the Ebony screen as a back up - for emergencies) it will be cheaper, even if I go (more than likely) for the HI-LUX Ultra Brilliant Matte 4.7 screen with the bespoke coverglass.
