'It's a terrible lens. You should stay away from it.'
Au contraire, I would like one, for environmental portraits, etc. I do have doubts it would give Zeiss-like depth to the image, given the huge dip in mid-frame below f8 - for nature subjects anyway, for which 28mm is an important wide angle FL.
I posted this information so people get a broader view of the lens and its characteristics.
cyra, another thought - tap the driver a few times, this can often loosen the threads a little, and help you remove it. Works better with metal drivers but might help anyway.
I tried several times, it made the driver hold better in the screw which is pretty wrecked by now - it didn't work though. I'll get some penetrating fluid, before I totally ruin the screw
thanks for the advise.
I also wouldn't mind to get that R 28 - I let one slip though on e-bay for 1060 €. I am not sure they are going for much less than that...

Make absolutely sure the driver head fits perfectly - David's ones do - then make sure it is exactly on axis, and apply plenty of downward pressure, have someone hold the lens square if you can, then make sure the turning force is perpendicular to the downward force and less than the downward force - I use pliers if necessary. If it does not break fairly easily (lots of pressure), leave it and use a very small dab of penetrating fluid, wait an hour and try again.
The screws are quite tight from the factory; I would have preferred tiny embedded allen bolts to countersunk philips heads. ...Show more →
I'd also recommend getting the screwdriver that's shown on David's site. I have four typical Philips screwdrivers, from #0 to #0000. The #00 seems to be the closest fit, and I did mange to remove the first three screws without any problems. The final screw was inordinately tight, and the #00 blade tip spun up and out, stripping the screw head. Took the lens to a local repair shop and for $20 had the damaged screw drilled out. With my next Leitax adapter, I will be ordering the screwdriver from David...taking a guess, but it appears that the US Philips screwdriver heads are cut at a more shallow angle, which doesn't allow the tip to seat solidly in the screw head.
I did order the screwdriver from David with the moount. That didn't solve it, on the contrary it seemed a tiny bit small for the screw and very easy to spin up and strip the screw head.
