I was about to suggest that. However, those hoods have become hard to find - at least for me - can't find 'em here in the US and the connection I had in the UK no longer lists them. Do you have a source? BTW, until I found a better hood than the stock one for my 50/summicron, I did just what Joe has suggested. I ended up with some Heliopan hoods, and they worked great.

Re: Lens Hood 31mm Ltd
Why is it worse on digital than on film? The flare is in the central part of the frame when using it on a film camera, as apposed to the edges on digital?

Re: Lens Hood 31mm Ltd
The fixed hood is not efficiently sized for the 16x24mm format, that's why. A 31mm lens should have a hood about 1-1.25 inches in depth at this diameter.

Re: Lens Hood 31mm Ltd
It's not really a flare issue with the lens though... the flare is a factor of the way it was used, right? IOW, any lens will exhibit a degree of flare under the right circumstances. In this case I would guess holding a hand up on the sunward side of the lens might have eliminated the flare, and of course a deeper lens hood (or maybe just totally circular) would have done the same.

IOW, any lens will exhibit a degree of flare under the right circumstances. Of course. All I'm saying is that the fixed lens hood is not very effective for a 16x24mm format DSLR, and the design of the lens makes it difficult to change to an effective one. In this case I would guess holding a hand up on the sunward side of the lens might have eliminated the flare, and of course a deeper lens hood (or maybe just totally circular) would have done the same. It's a street lamp causing the flare in this circumstance, out of the field of view captured on the sensor but inside the field of view of the lens with stubby lens hood flanges. It wasn't particularly obvious in the viewfinder although it shows up quite visibly in the image file. Shading the lens with my hand, if I'd seen it was flaring like that, would have solved this particular problem. So would a deeper, full circle lens hood.

The hood is a straight barrel but is stepped outwards from the filter attachment threads by about 4-5mm. The FA31 doesn't have the clearance for that.

Lens Hood 31mm Ltd
A 31mm Ltd fell into my lap for a few weeks, and the lens hood is a POS, especially for the Pentax digital. Since it's a built-in, non-adjustable hood, there's little that can be done with it. Has anyone come up with a better hood solution for this lens on a Pentax DSLR? I've a few ideas which I may be able to try, one of which is to use a screw-in hood of the appropriate depth. Might look ugly, but WTF ... any suggestions in this regard or otherwise would be most welcome. Shel
