This is the G1X with the Canon WC-DC58B wide angle lens from with my G9 and used with my G12. It is connected (almost) with the Lensmate G1X filter adapter. That is, this is the way the combination would look if the G1X filter adapter (either the Canon or Lensmate version) actually connected the camera and conversion lens. Those adapters will not make that connection.
Here’s the Lensmate adapter on top of the WC-DC58B. Notice that the threads on the lens are still showing. The adapter is not deep enough to accept the threads on the lens.
Here’s a closer view. Neither the Lensmate nor the Canon filter adapter is intended to be used with the WC-DC58B wide angle conversion lens. Well, neither was the G12 but the combination could be made to work. If the WC-DC58B were optically matched to the G1X then there would be an incentive to make an adapter for connecting them. For testing the optics, I used a crude but effective temporary connector: my hand. The combination kind of looked OK on the G1X display so I proceeded to my official wide angle test site.
I’ve used this location for several types of comparisons, including the wide angle adaptor on the G12 and G9. The image above is from the G1X at its maximum wide angle setting of 28mme. The G1X was mounted on a tripod so I simply held the WC-DC58B wide angle conversion lens up to it.
It works! Or does it? Well, almost but not quite. Perhaps a better “adapter” could eliminate the vignette. I probably could have eliminated the lens flare with a slightly different angle, lens hood or strategically placed hat. Canon could revise the G1X firmware to correct the distortion. So the potential exists for a new adapter and revised lens but would I buy them?
For starters, I’m not about to hang a heavy conversion lens – wide angle or telephoto – off the end of the G1X zoom lens. No sir, not me. Now, if someone were to make a rigid tube type lens adapter I would consider it but, so far, that product is not available and, evidently, must be a difficult one to design.
