Changing the focusing screen

...well it may just be me, but this is far from easy. Olympus supply a really bizarre tweezer tool which seems to be mainly designed to make life difficult. First of all, if you're going to try this, read the instructions. But not too carefully, because they're not very helpful. The trick is that everything is actually far less tactile than you'd expect. To start with, there is talk of a tab that needs to be pulled down using the tweezers. Well, first the aperture that gives access to this tab is too small to get the tweezers into. What actually seems to happen is that somehow you sort of brush the tweezers against the tab (certainly you do not "pull it down" as the instructions say) and then the screen swings down. Although "swings" is again too strong a word. Collapses is better. Then you've got to remove the screen by grabbing a protruding tab with the bloody tweezers. The thing is, this would be much easier if this tab was the same size as is illustrated on the instructions. It isn't, it's tiny, and again the tweezers seem to be designed to thwart you. By this point one starts to wonder if all this poking around in $1700's worth of camera is such a good idea. Anyway, once you've grabbed it the old screen doesn't so much slide out as (you've guessed it) fall out, although by some miracle it didn't (a) jam itself behind the mirror or (b) fall on the carpet. So, next step, grab the new screen and insert it. Well getting it out its bag is challenge #1. It obviously liked it in there. Then, using aforementioned tweezers, one simply places it on the holder. Now this is really where I lost the plot for a while. I expected to slide into some locating grooves or something, and much head scratching ensued. In fact, as it turns out you sort of balance it on the holder and push the holder back up. Somehow everything stays where you put it. It all feels a bit flimsy but it seems to work. Next, remove the grid screen, very carefully blow air on it to remove the dust that somehow went along for the ride, and put it back in again - at least you'll know how to do it by now! Is it all worth it ? I think so. I found with the standard screen, in what is after all a very small (albeit very nice) viewfinder, you need all the help you can get to keep horizons horizontal and so forth. But the instructions on such a delicate operation could be a bit clearer. And those tweezers should go back to the medical lab they came from...
