Canon TC-DC58C Tele Converter Lens for Canon A650IS, G7 & G9 Digital Cameras

...

nice optics for the Canon G9 Digital Camera, and, yes, it does what a teleconverter lens is supposed to do - allow you to zoom even closer and take very nice high-resolution pictures when attached to the G9 of subjects and views that are far away.

The teleconverter lens attaches to the G9 via a required lens adapter. Canon offers a plastic lens adapter - the LA-DC58H, but don't buy it...it's plastic for crying out loud. Lensmate makes a much more durable aluminum Canon G9/G7 58mm lens adapter that is of MUCH better quality - [...]

So, that's all good, but there are two somewhat annoying things about this teleconverter lens:

[1] Why are there no threads on the business end of the lens to accomodate attachment of a UV filter to protect the lens? It certainly can't be a difficult thing to engineer. The absence of threads on the lens body so owners can put on a UV filter - my gosh, that has to be an inexpensive and simple beyond description thing to do - is a seriously glaring design deficiency.

[2] With the teleconverter lens attached and the G9 zoom pulled back it looks like you are looking down a black tube with the subject or view you want to get a shot of showing up as a circle in the center of the view - which, or course, you are looking down a black tube. To be fair, the reason you attach a teleconverter lens is so that you can use the zoom to get even closer to the subject or view you want to get a picture of, and the black tube effect does go away when you use the G9 zoom to get closer to what you want a shot of. And for that, the teleconverter lens works as it should and gives you really nice pictures of further way subjects and views that you can't get with the G9 alone. However, it would sure be handy and nice and appreciated if the creative and very smart Canon lens engineers would bring a teleconverter lens that would allow G9 users who have the teleconverter lens attached to have the flexibility to take full-field-of-view pictures with the zoom pulled all the way back, and then be able to use the lens for its real purpose of extending the G9's zoom for those further-away shots.

Maybe solving the looking-down-a-black-tube thing is too much to expect, maybe it is optically and physically impossible to resolve. And it that's the case, fine...if it is becomse so annoying that a G9 owner can't get past it then there is always the bigger camera - bigger bucks - bigger lens path to take.

All in all, and mainly because of these two things, this teleconverter lens is just sorta ok for an add-on lens for a "tweener" digital camera like the G9 that is easily the best of the point-and-shoot digitals but doesn't reach the level of the big-time digital SLR's.

But I am just sure there are a lot of creative and really smart engineers at Canon, and if the MBA bean-counters would let them, they could come up with a much better and more elegant solution to solve these two annoying things about their teleconverter lens and still extend the optical reach of the otherwise exceptionally excellent Canon G9 digital camera and show the MBA bean-counters at Canon that their overly conservative sales and revenue estimates for G9 teleconverter lens were way too low.
