G10 + Lensmate + Canon 2x Tele-Converter (TC-DC58C)
1

Yes, this works. The new Lensmate G10 adapter set will accommodate the Canon TC-DC58C 2x Tele-Converter.

I don't think you can do this with the Canon-made G10 adapter, as I think it's made to accommodate only the new 1.4x tele-converter TC-DC58D (although this is my understanding, I could be wrong about it).

The Lensmate G10 adapter comes in three parts, typically used as A+B or A+C.

If you couple the A+C Lensmate G10 adapter parts, the Canon 2x Tele-Converter attaches to it perfectly.

There is vignetting unless the G10 lens is zoomed almost fully out, but not at the farthest two telephoto steps -- so you can get a vignette-free 280mm telephoto from this combination. This is almost exactly the same functionality as with the G9, where you get vignetting at all but the farthest three steps of the zoom. (Of course, it won't zoom as far at the G9 with the 2x converter, but performs similarly to the G9 in terms of zoom steps that vignette or don't vignette.)

thanks

Nice photos, interesting info. I'm sure there will be many grateful G10 owners.

I'm staying with my G9 for now, largely because I'm afraid I'd miss the extra tele range of the G9 (even though I more often want the wider angle of the G10 - who am I kidding? I'm just jealous!)

Except for those who owned the TC-DC58C converter with the G9, switched to a G10, and already got rid of the converter.

In that case, they might be a bit miffed. :-/

Now what you have to do is take an image with the converter and then move closer to get the same framing without the converter and take a second image. Then compare the two images to see if any aberrations exist

I don't know why the Lensmate page on the Sigma DPI wide angle shots doesn't work anymore, but it was a very interesting page showing the same corner detail of an image using 10 different wide converters. The differences are pretty dramatic. I'd be interested in seeing if there's a reason Canon had to create a new converter.

Argh, sorry about that, Dianne.

But maybe there's something I'm not taking into account. It all seems very puzzling that no official entity has hinted at compatibility here. Canon certainly hasn't (not anywhere I've seen or read about it), and even on the Lensmate site the TC-DC58C 2x converter is not mentioned as one of the options, I don't think. So, I might be overlooking some obvious flaw in use here.

I tried a handful of test photos late last night, and the images looked pretty good to me, even at 100 percent. I didn't go so far as to test the same framing with and without the converter, but that's something I'll probably try to do (if I have the time today, that is).

Also...with tele-converter, we might not see the same kind or degree of corner detail aberrations that might be seen with a wide-angle converter (not that I've really played with these kinds of converters before -- this is pretty new territory for me).

Was the Lensmate comparison page anything like this page on the G9/G7 (and the "corner" images shown lower on the page)?

Re: G10 + Lensmate + Canon 2x Tele-Converter (TC-DC58C)

Thanks Al! I have the TC-DC58N 1.75 converter from my G3/G6. I emailed Lensmate and specifically asked about compatibility and they said no. Thinking about it I couldn't see why their Raynox converters were different, so I was going to add a part C to my order and try it. This gives me hope. The converter was a light and useful addition to my Gs and seemed to yield acceptably sharp results.

If you have time, could you take a test image and inspect it? There may be focus issues that are not readily apparent. Probably if it focuses and looks good on the display, you are good to go! Cheers.

I didn't have much to work with last night, but I did take this shot of a stack of CDs from about 10 feet away. The image is resized but not cropped...and it's a bit crooked, but looks pretty good in terms of image quality...and maybe shows enough to get an idea of how the adapter/converter combination does. Print quality on the back of CDs often leaves a lot to be desired (all these fonts vary wildly), so take that into account when viewing this. I'll try to do an outdoor photo today (if it stops raining long enough).

Yes. It just showed the corners. The differences were more dramatic than on the Canon page.

Re: More Photos of the Lensmate G10 Adapter Parts

Jeez...this thread sets a new high for adapter-p0rn

I'd post pics of my custom A710 adapter, but who wants to see pics of old adapters?

Re: Image Sample

Thanks for the quick response Al! It certainly looks like its doing the job.

This is great news, it means I'll be back where I was with the reach of my G6 and all the improvements of the G10. I'll probably just use the 58mm polarizer on adaptor section A as Lensmate describes and keep the extender on part C. This gives me polarization on the wide to normal shots and a quick zoom extension when needed. I might even spring for a second part A so each is just a simple bayonet mount swap. Fast, easy, light - 28 to 250 mm (with my 1.75x) and IS in less than a pound and a half. Can't beat that!

Thanks again!

Re: More Photos of the Lensmate G10 Adapter Parts

Well...it seems as though the complexities associated with creating a good Lensmate adapter (or perhaps more appropriately, "adapter system") for the G10 were such that it far surpassed (in design concept and execution) the simpler single adapters of the past. A lot of questions were raised and speculations made about how the adapters would work, why they were set up as "multi-stage," how this affected wide versus telephoto photography, how the pieces and parts were supposed to work together, etc.

My main purpose for this thread was the discovery that one could indeed couple the old 2x converter with the new Lensmate adapter, which came as a big surprise to me. Again, I still might not be recognizing some obvious flaw in the use of the old 2x converter with the new adapters, but it seemingly works just fine (with only minor limitations that mirror the limitations of the adapters/converters used with the G9).

Ben Hermann started a related thread, but I didn't want the tele-converter aspect of this to be lost in his A+B Lensmate adapter thread, so I started a new one. Unfortunately, that also gave me an excuse to post more photos of the rest of the adapter parts....so I did.

Re: Image Sample

You're welcome, nolten...I'm glad you're finding the info useful. Hopefully, everything will work out on your end in terms of the bayonet mount and matching threading for the converters (I'm assuming it will with no problems, but I'm doing a lot of guessing with that).

I also think you're on the right track with considering two of the part A adapters, which will make switches quick and easy, with a lot less screwing/unscrewing of the actual converters and filters (a bit of a time-consuming and somewhat cumbersome pain).

These adapter/filter/converter combinations certainly do open up some interesting possibilities for expanding what the basic camera can do.

Actually, I'm just glad I had the 2x converter available to experiment with.

I get the sneaking suspicion that no-one really wanted owners/users to know this was an option...

I'm sort of waiting for someone to come up with a statement of, "You know, you really shouldn't be doing this because (fill in reason here)."

Ha! Thanks...

For about half of my music, I tend get a lot of "Who's that you're listening to?" followed by "Never heard of them."

Re: Image Sample

When I got my 1.75x adaptor for my G3, way back when, I tried it on every 58mm filter mount lens I had. Some worked, some didn't and I couldn't find a pattern. It worked best on my 100 mm macro but, in general, it didn't add much except for the Gs. I've had two Gs which I use for backpacking and other light travel. The extender has been a really useful addition. Being able to use a polarizer is, I think, critical for landscapes and so a deal breaker on P&S cameras except for the Gs. Lensmate has been a great accessory here. If I could simply add a picture here, I'd show you a G3 image from Bora Bora in 2003 that is just lovely. I could do better today with my 5D but it still makes me smile. The extender came in really handy with the Tahitian dancers ;-).

Your test shot shows the extender works so I wouldn't worry too much about if its supposed to or not. I'm expecting Santa is going to deliver a G10 in a couple of days and I'm excited about having a camera light enough to backpack with that Rockwell and Reichman think can match up to a 5D. Your posts have helped me evaluate the critical Lensmate piece and I thank you. I had to guide Santa after all.

Your music list looks much like mine. There are a few new names and I'll look up these on itunes. Cheers.

Wait a minute ...

"Silver Tongued Devil" is available in that new-fangled format?
