There are several good threads on this forum discussing wide & teleconverters. Here's a recent one:

Scroll down to November 12th--Andy posts a great link to a comparison of many lenses. He also posts some samples from the Olympus he owns.

Short version: Canon and Olympus seem to be the highest quality, and the most expensive. No big surprise there--cheap glass is, well, cheap. Steer away from ebay specials. Kenko, Raynox and Tiffen all seem acceptable, with varying trade-offs.

Also, check http://www.lensmateonline.com/g3_samples.html for some sample images. Their adapter is also highly rated.

thanks dbump. :)
--problem is ,HOW with newest G6 ...- probably the same as G5 lens characteristics but I am NOT sure. - I know,its too early for more information... - I am using Sony VCL 2043 C - very cheap one (and big one) and must to cut almost 1/3 of picture :lol: - but rest of the frame is great and extremely high quality.( and 2x !!)--- how about B-300 Olympus -it was one of the best- but can I use it to new G6..??!!!!

I believe all the same conversion lenses that work with the G1 - G5 will work with the G6; the optics are pretty similar (identical to the G3/5), they simply require a different adapter tube. The adapter tube is just that--a tube with no glass elements. One end has the bayonet mounting that attaches to the camera, and the other end is threaded for attaching filters or lenses. Canon makes their own, and www.lensmateonline.com also is making one (should be available pretty soon?). The Canon adapter is plastic, and has a 58mm thread; LensmateOnline's is aluminum and is available in both 52mm and 58mm sizes. The 52 blocks less of the flash and viewfinder--and it also allows you to use smaller (thus, less expensive) filters. They have some recommendations on which size, based on what lenses you plan to use.

I've had the plastic Canon adapter with my G2, and never had issues with it, but if/when I get the G6, I think I'll go with the Lensmate.

dbump - adapter for G6 is metal (no plastic) and MAXIM. expensive (50 $ ??) - I have one ,and 'crying' all the time becouse of price 8) - its for 58 mm filters only..

you wrote :I've had the plastic Canon adapter with my G2, and never had issues with it, but if/when I get the G6, I think I'll go with the Lensmate."--
dbump- I think its GOOD to lens to use adapter ,for example becouse of dust and sand influence on mechanical parts .
-- and for me, it was also VERY comfortable to handle a camera...

Catcher,

you're right, if you use an adapter, you protect the lens element of your camera. It's also possible to hold it easier. When I first got my adapter (Kenko 52 mm), I always used my G2 with that and a polarizing filter.

However, it makes the camera bulkier.... I found that out and now use my G2 most of the time without adapters.

As far as the thread diameter is concerned ... on a teleconverter, vignetting might be an issue. I have the Kenko LD-20T on my G2, and there is vignetting from 1x until about 2.5x zoom. That means, I can only use it at full zoom and zoom out a bit. this gives me an effective range of 35-105 (G2 without adapter) and 190-210 mm (guess, with the adapter). Would be nicer if you could use the camera from 35 - 210, but from what I've heard, this is the case with most teleconverters. It's the case with the Olympus TCON-17, maybe also the Canon.

To determine whether a lens has vignetting with a certain adapter, you'll have to test it. So I'd suggest going to a reputable Canon shop and test the TC-58 for that feature.

However, vignetting is more a problem on a wide converter, because if you zoom in, then you use the wide angle effect. My Olympus WCON-08 (55 mm thread) does not have vignetting, so I have a usable range of 28-90 (with WCon) and 35-105 (without WCon).

Theoretically, a 58 mm lens should be less prone to vignetting than a 52 mm lens, because the opening is larger. So maybe it's not a good idea to buy a lens that has a 27 mm or 43 mm thread.

But take a look at this photo: It shows the back of my 2 converters: Kenko LD-20T and Olympus WCON-08.

You'll notice that although the Kenko LD-20T has a 52 mm thread, the rear element is much smaller (maybe around 30 mm). So maybe the 52 mm vs. 58 mm doesn't really make much difference here.

Hope that helps :D

Best regards,
Andy

Andy,
Very interesting picture--definitely worth checking the diameter of the rear element!
Catcher,
I didn't know Canon had moved to using a metal adapter tube. That's great!

Like Andy, I tend to mount my adapter only when I need it, just because of the increase in bulk. I wish Canon had threaded the lens on the camera body, so we could mount filters directly to it. I can understand requiring the adapter tube for heavy conversion lenses, but for the most part I just want to pop a polarizer on there, and the tube seems like overkill for that...

Andy !
great thanks for such a care post.
-I hope Olympus is better.- also becouse of more light..


dbump.- thanks for answer. - I dont know too,why they (Canon) cant allow us to use filters straight at the lens.. :? - anyway,I am using adapter ALL the time,also,becouse of the dust !!
