Split focusing screen, Yes or No.

Just want to know if anyone's added a Katz's Eyes focusing screen to their E-330. According to Kats Eyes, it's not possible to self change that focusing screen. It must be installed by a camera technician.

I am interested in getting some bright f1.2 manual lenses and focusing on this E-330 can be pretty difficult due to it's dark VF.

Re: Split focusing screen, Yes or No.

The trouble or disapointment you can get: if you use a lens that is not designed for digital you will get less sharpness than you would if you used it on an analog camera.
This is due to the fact that lenses for analogue project the image under an angle and not straight.

If have taken a test with a verry good OM 1.8/50mm with the Oly adapter on the E410 and it came out a lot less than the 25mm setting on the E410.
Both used f:8.

If you need more speed, get the Sigma 1.4/30mm which is designed for digital.

Re: Split focusing screen, Yes or No.

I have a 55mm f 1.2 Zuiko on an E400
The problem I have found is that front and back focus errors can occur due to the adapter (OM->4/3) and that is by eye with the normal E400 screen
So you still end up stopping down to increase the depth of field

Re: Split focusing screen, Yes or No.

I don't know if the E330 internals are different to the E400, but I changed my E400 to a Katzeye last year. Its a fiddly job and takes some care.

The jury is still out for me. It may well help to focus manual lenses if your eyesight is 100%, but no longer trust myself to get it spot on with short lenses (less than 50mm) so one day I will change back to the original screen.

Re: Split focusing screen, Yes or No.

Since an 'incident' with a flash a year or two ago I need to use a split focussing screen now for my manual lenses, fitted to my E300 in a couple of fiddly hours, for me it's the difference between being able to manually focus accurately and not.

Re: Split focusing screen, Yes or No.

Have any of you ever thought to use a tape measure and the distance markings on the lens

The great advantage of digital is it cost nothing to try these things.

Simply set the lens to minimum focus distance, measure from the sensor plane to the subject and see if the resulting image is sharp (using a few different appature settings)
