threads on lens barrel Does the SX30IS have threads on the lens barrel so you can add on UV filters etc.?

I'll take a guess too.

It looks like they use the adapter ring to fit 67mm filters to avoid vignetting with the wide angle lense. Since the number 67 appears in the code for the adapter and the number 60 appears in the code for the lense hood, I'm "guessing" the lense has 60mm threads, which don't exist in any normal filter size.

P. Hudson,

I made it look confusing. I think the lense thread is 60mm. The adapter would be 60mm to 67mm to accept the 67mm filters. That's the best guess I can come up with.

I didn't get back in time to edit, but I would normally call it a step-up ring. It just has the unusual 60mm threads for the SX30 lense.

I don't want someone to get confused and think this is something strange, it's just not a standard size lens mount, if I'm correct.

OK, i have the answer!

the guys over that the forum linked me to canon's Asian's site where i was able to downloaded an english version of canon's manual that says the adapter (canon #FA-DC67A) is definitely required to attached 67mm filters.

here's that link: http://support-asia.canon-asia.com/contents/ASIA/EN/0300419501.html (then see page 41)

so, unless you're willing to buy the adapter, there is no apparent way to mount a UV filter, regardless of size.

thnx Les for helping answer this question.

Lensmate has updated its sight and now includes the SX 30 IS for the adapter ring and filters.

i too am interested in using a UV filter to protect the lens.

i've read at canon's website that the filter size for the SX30IS is 67mm, yet in other threads i've read that a filter adapter is also required:

"...an optional lens filter adapter allows the attachment of 67mm filters such as the Canon PL-C B 67mm polarizer filter..."

the best that i can understand given this limited info is that you'd need to buy a $25 adapter before you can use 67mm filters.

and no filter size is shown on the lens itself, which is usually the case if a lens can take filters:

on the other hand, images like this one show internal filter threads:

so its anyone's guess....

good guess Les, but Canon's own SX30IS "additional supplies" page offers both 67mm filters and the adapter:

http://www.usa.canon.com/cusa/consumer/products/cameras/digital_cameras/powershot_sx30_is#SuppliesAndAccessories

i've just posted this question at a canon forum where a couple of folks in Asia already have SX30IS cameras in hand.

when i hear what they have to say about all this, i'll re-post their replies here.

if this all holds true, then the only thing that makes it strange is why canon just didn't go with a standard filter thread, like 58 or 62mm, then an adapter wouldn't be required. (two millimeters in either direction from their 60 is not consequential). i guess the only answer to that would be your vignetting with the wide angle lens which requires the large 67mm and thus pretty much necessitates the use of a step-up.

which in turn raises yet another question for me:

you said: "...the number 60 appears in the code for the lens hood" but doesn't the hood bayonet onto the outside of the lens and not screw into the filter threads?

the photo i linked above seems to show that:

There has been a LOT of discussion about the auxiliary filter (or extender lens) adapter for the SX30IS over on the DPReview Canon Forum. Guy named Bradly has one and has installed the tele extender lens (Olympus TCON-17) that I have been using with my Panasonic FZ50. Here's a link to get you going to pull out all the required info.
