Wide Angle for Canon G6

[david_s3]

I'm thinking about picking up a Canon G6 for hiking and backpacking.

My question is, are there any good wide angle add-ons that will go

down to 20mm equivalent? I believe Canon's only goes to 28mm, or .8x.

Thanks!

The widest third-party lens that I know of is the Raynox 6600 .66x, which is 23mm.

I know you are looking for wider - but - I cannot imagine not having the Canon WA with

my G5.... It is big and heavy, but it really helps to produce great images.

Actually, the Canon lens is eqivalent to a 24.5mm (.7x). I had one for my G5 (which

shares the same lens as G3 and G6) and overall it is a good lens, though it is big.

Combined with the adapter needed to mount it this lens (and probably any others you

might find) will be as larger or a little larger than the camera itself, and weigh as

much or more.

 

The Canon lens has excellent sharpness, but does lose some contrast, but focusing

with such an effectively short lens was extraordinary. You can basically shoot

everything at f/2 and just forget about it.

 

Like all lenses of this type there is considerable barrel distortion, which can be easily

corrected in freeware (like Panotools) or low-cost PS plug-ins (like "Debarrelizer" that

I use from theimagingfactory.com).

 

Bottom line is If you can live with the bulk/weight of the lens and adapter for

backpacking you'll like the results.

 

FYI - with my G5 I also discovered that by putting a 58mm IR (hoya R72) between lens

and adapter that I could take advantage of the lens' huge depth of field and still get

sharp IR images.

 

Good Luck!
