K-01 hood for 40mm XS pancake lens

I found this on eBay. When I ordered, it appeared that it would be a singular and smaller 27mm hood, but it seems that their offering is actually a 27-37mm adapter and then a 37mm hood. It's a little bigger than anticipated, but it looks kinda cool. What I really do like is that it improves the image quality, as hoods naturally will.

Can you post an example of the same picture taken with and without hood to see how much does this lens benefit from it?

In Leica-land, a vented hood is said to make it
"so it looks like a real Vietnam war camera."

How much does it affect the AF?

Aren't vented hoods pointless on cameras without a rangefinder or offset OVF.
The vents serve no purpose on a mirrorless camera which uses the back LCD and TTL viewing.

yeah, I think the point of the vents is to see through with a viewfinder, but if that's what you've found, and it works... I think there was a hit when I searched for "27mm lens hood" at either Amazon or B&H, but I haven't bought one.

Lens hoods, in general, can potentially increase overall contrast and reduce flare points. I use them whenever I can.

Does look kind of cool but since purchasing the FA43 I have not used the 40XS at all.

It doesn't affect the auto-focus at all. It doesn't rotate with the focusing. I'll try and do some with & without comparative shots and see if we can detect the image quality differences. I noticed it when there was strong side lighting. With the hood blocking that, I found a bit better contrast and color depth.

Interesting. I would've thought it would since the camera has to move a lot more weight...

Compared to a "beer can" zoom, turning a 40 XS plus a hood probably isn't much.

On a slightly different tack, since a hood increases contrast, I wonder if it helps the speed/accuracy of the CDAF system?

I almost put together the same setup myself but then I had what I think is a better idea. I bought two of the cheapest 27mm filters I could on Ebay, then took the glass out and painted them black. If you find some cheap black ones then you're set. My total cost was like $5. It's not the prettiest solution but i think it's probably the most compact. The filters are roughly the same thickness as the front focusing ring on the XS. If I hold the camera at a similar angle to your photos it seems to provide similar coverage.

bradsarno, can the original lens cap still be used when this hood is installed? I would imagine not...

No, the old cap can't be used with this hood on, BUT a standard 52mm fits the hood perfectly.

Vented hoods are not pointless... they are still hoods no matter on what camera/lens they end up and they do their job well + they look more stylish than a simple boring round piece of metal/plastic.

Btw, you guys know that there are plenty of 27mm hoods out there...

Thanks bradsarno. mrNewt, there are lots of listings, but not that many options, I think. Basically there's the square camcorder hood, the vintage (expensive) slip-on hood, the rubber hood, and the one we've been talking about here. Of course, once you figure step-up rings, things open up totally, and even at 37mm there are many more options.
