Hello everyone. I bought a Powershot A70 last week and so far I'm loving it. I've noticed some pictures are soft, but thats another topic.. My question is that I want the addon lenses for it but I read that the Canon brand converter lense blocks the flash. That just is not ok with me at all. Will this http://www.amazon.com/exec/obidos/tg/detail/-/B0000BZLSZ/102-4026905-5944933?%5Fencoding=UTF8&coliid=I34LHORONCV3Q5&col id=3GAT6BIWVLUOH

its 52mm just like the Canon's so I'm hoping it works with the A70 also. Thank you everyone. Also does anyone know of different macro,etc brand lens then Canon.. they're just too expensive for me. Yes, I know I'll most likely lose some quality using a cheaper brand but I just can't get the more expensive Canons.
THANK YOU! :)

Also look at www.lensmateonline.com - they do A80 stuff, not sure if it's compatible with the A70 but worth asking.

Ogrt:

The lens adapter itself blocks part of the flash and the viewfinder of the camera. It's a design flaw. As far as lenses are concerned any auxillary lens that fits the screw mount of the dapater will work. I'm using an old lens I acquired with a pre-interchangeable lens SLR back in the 1960s and it works fine. As far as the flash goes, I bought a cheap electronic flash and attached a small light sensitive bulb making the flash into a slave. When I use the camera in manual mode (which I do most fo the time), the on-camera flash triggers the slave which I could place anywhere t illuminate the scene from sides or top or bounce, etc. The slave flash has given me a lot of flexibility so don't dispair.

Ah, thanks for all the tips. Where can I get those kind of flashes and how much do they run? Those would rock since alot of pictures I take are indoors.

I'm no expert but I bought mine in Woolmart for about $25 (Canadian). It's a Vivitar. Make sure the flash has a small jack (it can be used off of a hotshoe). I want to the camera store and bought the light sensitive bulb (I can't remember what they call it) for under $30. You plug the bulb into the trigger of the flash. It works very well and you can experiment with light placements.

You might try a 37mm adapter and smaller lens.

Here is a look at the 37mm adapter on the A70:

Here is my reflective paper reflector to help with the flash problem:

I have used these: fast service and good price for US only:

What a wonderful set of suggestions. I am in awe. Your little light pipe is a very neat idea. How do you store it and mount it? Do you just use tape?

It's a bit fragile, so it's hard to travel with. It is attached to camera with double stick tape. Here are more detailed instructions:

"My idea was to use reflective silver paper on the interior of the tube so most of the light would exit the top of the tube. The tube looks like a small rectangular periscope.

Frosted Scotch Magic tape was used on the top outlet of the flash tube to defuse the light for even illumination.

The material I used for the tube was the silver mirror paper found on a wine bottle gift bag that cost $2.25. The tube was attached to the camera with Scotch tape.

The photos show that it works. The photo taken with the Canon Wide Converter WC-DC52 is under illuminated and the flash does not cover the whole 24mm shot, as would be expected. The shot can be corrected with PhotoShop levels, however. And it may be possible to use the Scotch tape more effectively to even out the flash and redesign the top of the tube for better light reflection.

For close-up shots, the tube eliminated the dark shadow caused by the LA-DC52c lens adapter. It would also be possible to construct a tube that went straight out from the camera to the edge of the lens adapter to bring the light closer to lens."

I also made one with a PEZ dispencer with the sliver paper inside, it is attached with velcrose (sp?), but it is much heaver and there is too much light leak with the velcrose, it's too far from the camera.
