    Review: Bohema Studio Poly/Acrylic ground "glass"

    I just got an 8X10 Acrylic ground glass from Bohema Studio, purchased on the auction site.
    The piece was shipped in a padded envelope with no other protection, and i think that is a testament to how strong and resilient this material is.

    It is indeed VERY bright, brighter then any GG i have seen, but not sure if i can compare it to a fresnel lens combo. It is about X2 thicker then a glass ground glass, but still sits well in the Deardorff back. BTW - the default size they cut is a perfect fit for this camera (as well as Calumet C1).

    Grid lines come as an added extra option, and are standard at 2cmX2cm, i think for future GG's i will ask for either 1" or 1cm, which i think would be more useful for me. In any case, you can ask for which ever grid spacing you like, just be sure to specify.

    Will post a photo shortly.

    Is it ground or is it a film that's been applied to the plexi?

    Does it flex at all?
    How is fine focusing with a strong (8x or more) loupe?

    Finally found it, it wasn't on the .nl site, had to go to the .com site. I am curious too if it flexes, I am interested to replace my glass groundglass without grid of my travel 4*5 Galvin.

    No flex as far as i can tell, its extremely thick (3mm+)
    Will check with a loupe later today and report back. From a naked eye point of view, its better then the cambo glass i have, which i always thought was near perfection.

    It would be great if you could follow up with more info when you've had a chance to use it.

    Does it warp with temperature changes? Is the smooth side scratch-resistant? What's the grind like- coarse, fine? Any hot spots? Is the grid scribed or drawn? 3mm is pretty thick, any weight saving over glass?

    Re: Review: Bohema Studio Poly/Acrylic ground "glass"

    Last night I received the custom made acrylic ground glass from Bohema Studio: very nicely made with fine grid lines and cut out corners which I did not have on my old ground glass. It replaces the rather dim and slightly damaged ground glass of my "light weight" travel 4*5, a Galvin.

    Acryl is than a safer option. The acryl is rather thick at 3mm, but it fitted perfectly in my Galvin, it's brighter than the original one, it seems a little bit coarser though. I have not had the change to take it out, but thus far I am pleased with it. Since it's acrylic it will scratch more easily, I do not think it can flex under a loupe (which I do not use, my eye description is such that if I take of my glasses I can focus good on the ground glass)

    I have no affiliation with the seller, but since shipping from Poland to The Netherlands is cheap it's total price was attractive (54 usd inc shipping for a custom made acrylic with grid lines (1*1 cm) and cut out corners)!

    best,

    Cor
