Yesterday I got a 2-13 off eBay for just 39€ (incl. mail).
Cannot wait to get it this week!
Really eager to see whether it does make that big a difference.
I will report back to the mothership. 😉
When I got the screen, it was not in described condition. A rather annoying scratch ran right through the centre of the screen on the upper half above the focussing split-image.
😡
Anyhow, it's very usable and got another 10 bucks cheaper for me. I suppose, a B-C condition 2-13 for 29€ is not so bad.
LUCKY!
I've been looking for one for a while now...had a 2-4 screen but didn't like it in my OM-2n. Now that I have an OM-4T, wish I had it back 🙂
After having done some rudimentary comparison between the 2-13 (in the OM-4 Ti w/ 40/2.0) versus a 1-13 (in my OM-1 w/ 50/1.8), I did notice a difference in brightness of the screen.
While definitely recognizable, I wouldn't consider it worlds apart.
(Probably enough to throw off an OM-2's meter, though. But I couldn't testify due to a lack of OM-2s... now, there's an idea.
😀)
If you consider the screen for its brightness alone, I would
not spend 100+ Euros (prices which seem realistic from my previous experience).
Now, where I could see a definite and remarkable difference is the microprism collar around the split-image. Here, the microprism is much, much finer than the one found on the 1-13.
My verdict (for now) would be: If you can get a fair deal, say 30-60€ depending on condition, go for it.
I'd suggest you try having a look through someone else's 2-13 viewfinder before you spend 80-120€ on such a screen.
Of course, this is just my opinion and I have yet to "field test" the screen properly.
