Giotto Rocket Blower - which size?

I'm about to get a rocket blower for use on K10D.

Big one looks like needing a fair bit of space when travelling, small one looks as though it might be a bit short of puff.

Any thoughts on which is best size for effective use, please?

I have the big one, which I chose having made exactly the same observation as yours. Very effective - used it several times to shift dust from the sensor, successfully every time.

I'd say it's worth it.

Just to be annoying - I have the small one and find it perfectly adequate and have also cleaned specks from the sensor 2 or 3 times with it without problems. It's also perfectly sized to stick in a bag

I went for the big one and find it brilliant for removing dust, never used the small one so can't really comment. Does take up quite a bit of room though.

Has anyone chopped the fins off it?

I think you'll find that they're essential for stability in flight.

Absolutely Dan. My 3 year old son is obsessed with the rocket blower. I think it is simply that shape for the 3 year old in us all!

I did read somewhere that the the holes in the fins are to allow it to be carried on some sort of lanyard around your neck for easy access...good idea, though don't think I'll bother.

I think if someone needed to have it round their neck all the time, there's something seriously wrong with the way they're changing lenses.

I use mine every other week or so. Not sure if it's a large one or not, it's about the size of a lemon, but does the job no bother. I squash it down and it easily fits in my bag.

I tend to use mine a lot for removing dust from the from element of the lens, so in that respect I guess it would be handy for that. Though I'll still keep it in my bag until I need it. Sounds like the large on, I think the smaller one is the size of a pool ball.

Thanks for responses. Think I'll go for the happy medium!

I understand the fins have two purposes - to stop it rolling away and to keep the air inlet off a dusty surface if stood vertically.

So which size do you use?

In the Uk shops it seems to be only the large one, while on ebay I cand find some small and medium as well from Hong Kong.

I have the Q-ball, which is the smaller one with the tiltable tube. It works great.
I haven't used it since I have my K20D though.
The blower and a Arctic butterfly were the only things I used when cleaning the sensor of my *ist-DS.

I've got the large one and I love it.

I've only ever used the Rocket Blower and the built-in sensor shake on start-up. In two years I've not had any dust problems and I've never felt the need for a wet clean.

Get the big mutha, size does matter

Did read that someone had theirs confiscated by BA, so take care if you are travelling by air
