I've found a couple of focusing screens, which are cheaper than katz eye/haoda (whose prices are outrageous imo):
eBay (chinese): Click here to see on Ebay
focusingscreen.com (taiwan): http://www.focusingscreen.com/product_info.php?cPath=21_45&products_id=98
Have you tried any of these? i think i'm going to buy one to try it. The chinese one is just $27 after all.

update: it has arrived and works great (see later in this thread)

I had to fine adjust the screen to my 350D with tape but now it works like a charm - better than the AF-adapters! _________________ Personal forum activity on pause every now and again (due to job obligations)!

I bought a cheap focusing screen from Virtual Village via ebay. It worked ok with a little bit of fiddling, packing the shim, but the inherent focusing difficulties with my Canon 10D led to me taking it back out and re-inserting the factory screen. I'm certain a later model of Canon would have no problems; the 10D was notorious for inconsistent focus, but I found that out after I bought it. _________________ Dave - Moderator

Hi.
Be wary of Chinese split prism focus screens. I purchased one for my E-510 from terrence_camera (resells focusingscreen.net screens) and I've been getting some serious front focus issues. The problem is less apparent with the original factory shim removed (the VF no longer has straight edges now...), but focus is still a hair off. From what I've been reading, front focus is caused by a focus screen that rests too close to the mirror. I assume I'd have to file down the edges so it lays recessed in the slot, but I have neither the skills or means to do so. Prepare to be handy if you do choose to buy a cheap Chinese screen.

The focus screen for my Canon 400D arrived today and it works great! unfortunately it comes without any instructions so I've had to put it and remove it like 3 or 4 times, until i've found out how it's supposed to be placed (and it's quite dirty after so much handling, and i've even managed to make a small scratch. i'll have to take it out again to clean it).
I'm really happy with the results. I first tried with a 50mm f/1.7, and the focus is dead-on. The microprism collar is usable until f/4-f/5.6 and the central split prism is usable until f/5.6-f/8. Stopped-down metering is perfect until f/8, basically when you see the prisms start to black out (which happens at f/8 ), you have to underexpose 2/3 stop, that's all the adjusting it takes. Then I tried with an AF lens, 17-70 f/2.8-f/4.5. This one didn't need any adjustment for exposure in the whole range, f/4.5 is sufficient to prevent the prisms from blacking out. The autofocus works correctly and the split screen matches perfectly. All in all, a great product at a great price ($28 +free shipping)

I got mine from that same eBay vendor this past weekend. If you had gone to focusingscreen.net , there are instructions (in Chinese- just do a Google translation)....I got it in without a hitch, although I need to move it over a hair as the central AF bracket isn't exactly lined up the the 3mm split prism circle. It's really close enough that I can still use it without problems, but it just looks weird. I'm printing off a focus test sheet to check for front or back focus issues, although it doesn't appear to have any (just to be sure though, my old tired eyes need reassurance)...The screen came with an additional shim, but I didn't use it & the instructions appear to indicate that it's only needed with an Ec screen. I just got the cheapie ($24) screen. I have some othe oldder manual focus Nikon screens that I'm going to cut down & try out to see if I like them any better...As for the split blackout, Most all of my lenses are faster than F5.6 & the ones that aren't are AF lenses anyway & it won't make any difference as long as I use them in AF mode... _________________ Cameras-Nikon D300, D7100,D610,FE2,FTN ,FT2,N90s, Olympus Pen EP-3 & Olympus OM-D E-M10

How are you finding the screen now?
I have mine installed all the time. I find it ok when there is something vertical to align but I am utterly useless at at portraits with 135mm or longer lenses. I took a few shots of my wife against the sunset @F4 and every single one is off. GRRRR!!!! I stopped 1 down to F8 and it's acceptable.
I'm wondering if a better screen may help or maybe I just need to practice. _________________ Casual attendance these days |

take a EE-s at 25e, I use only that
prism is nice for landscape but if the lens is correct you can just set infinity with same result
matte is superior for fast action
you will learn to focus anywhere in the frame and free yourself from the 98% of photographer who always put the subject in the center |

I did try it before but not sure how useful I found it. I guess not very as I bought a split prism. _________________ Casual attendance these days |
