G11 accessory lenses

Does anyone have comments or experience with the use of the Tele Converter - TC-DC58D lens for the G11? I'm thinking of buying this camera and wanted to know if this additinal lens is worth the purchase in terms of performance and utility. Also, does anyone know if you can attach polarizing filters to the the G11 lens or the accessory tele converter lens?....thanks in advance for any help...I am a new member!

I have not tried that teleconverter, but I have several ranging from 1.4x Olympus, 1.7x through to a 2.2x Rayonx. Fitting is easy with an adapter tube set which has been discussed in detail on here, see the links below. In general while they work quite well, I do find that with the quality of the sensor and the image size it is easier to crop the image. The problem tends to be getting the subject in the frame, focusing can be quite slow and I must admit that the DSLR is the better tool for that job. However, the wide angle converter is a different beast and I find the WCDC58B (0.75x takes the camera down to 21mm) to be excellent and very usable, I always carry mine when I go out.

Re filters, with the adapter tubes they are great. Polar works well, but it can be difficult to judge exactly what you are getting. Close up (to get macro at the long end of the zoom) will give great results. The other option you may want to consider are square filters, such as ND grads, they work very well.

Suggest you look at the main G11 photo thread, lots of converter work in there, plus you may find some of these of interest...
Good luck...

John,

I have not used my WC-DC58B (0.75x) lens with my G11 yet, so I took a few sample shots, and find it has a lot of distortion/fuzziness on the outer edges (all four directions). Here's a crop taken from about the center of the shot to the far left edge.

I have the Canon TC-DC58C (2.0x) tele lens that I'm using on my G11. I was using it on my G9, and it works fine on the G11. However, there is no setting in the menu to tell the camera you are using it. The menu setting just tries to compensate the image stabilization system for the TC-DC58D (1.4x) if you choose to use it.

I use the Lensmate tube system with my G11 and lenses. You need to use parts A and C with the tele lens.

Here's a shot taken using the 2.0x tele lens on the G11 this afternoon. It gives good results, and allows you to shoot at full resolution, and get a full sized image to play with, rather than cropping. This shot was hand held at 1/60 sec, with a zoom equivalent of 280mm. I also use Continuous IS and AF, plus Servo AF. They seem to help.

Hi Dennis, I am sorry for the delay in responding, I must admit that I have not had anything that looks quite like your problems! I stand by my posts that the WC-DC58B produces acceptable results, while I can occasionally get a bit of chromatic aberrations (fringing) in the extreme corners, this tends to be when taking fine detail object, such as thin tree branches against a pale sky - but for the vast majority of subjects it is not a problem and the results are very acceptable!

As you say you get good results on your G9, the only thing I can think is that it may be the lens adapter you are using? I cannot remember which unit you use, but you could try holding the converter to the front of the lens and see what sort of result you get. I bought a Chinese clone unit and found it to be excellent with very tight tolerances e.g. filters or supplementary lenses are physically very close to the lens.

I was using my WA combo extensively over the weekend and while I have posted some B&W conversions on here, I will post some clean images below.

This is almost straight out the camera - I had plenty which looked similar.

Further to my last, I have had a quick play, here are some crops - same kit...

Basic image - now this is one old door, dates back to 1600!

John,

Thanks, excellent photos, and results with that lens. I tried holding the lens up to the camera, and got the same results as before. I tried a different experiment, and took some shots in Macro, up close to a bird bath. The results look good, but I need to try to get shots like you are posting that are in portrait orientation of a scenic vista.

Here's my macro shot.

I'm confused as heck for these accessory lenses. I am trying to find information on how they work and stuff but I see nothing. Can anyone give me links or explain how these work? Thanks!

This link to Lensmate shows their system of three parts of a tube system called adapter tubes.

http://www.lensmateonl​ine.com/newsite/G10.ht​ml

You use the tubes according to what you are trying to accomplish. Here's a shot of my G11, three parts of the Lensmate adapter tubes, and my wide and tele lenses, and a polarizer filter (72mm). The ring around my G11 lens has been removed, so the adapter tube assembly can be attached to the camera using a bayonet mount (turn and click).

Here's a shot of the G11 with the wide converter attached to part A of the adapter. I only attach part A to allow me be at the widest zoom on the G11 (28mm equiv) and not have vignetting (black circle around the photo).

Here's what the wide lens looks like when attached to the G11.

Hope this helps let you see how it all works together.

This helped a lot, thanks so much for posting this! Where did you purchase this? With the tele connected, what is the focal length? Approximately, how much did this cost?

The tele and wide converter lenses are made by Canon, and they are still sold through Amazon. They were originally made for the G9 and A650 cameras. The tele at full zoom converts the G11's 140mm max to 280mm max. (140 x 2 = 280). The wide converter at full wide converts the G11's 28mm to 21mm (28 x 0.75 = 21). Here are links for them on Amazon.

Further to Dens response, you can also get away using other converters. I have several, my first was a very cheap, but high quality Olympus TCON-14B (it comes in 62mm thread), which works very well, does not vignette and takes the camera out to just under 200mm (in 35mm equiv). I also have a Raynox 2020x which is a 2.2x, while being a nice quality product, it does tend to vignette and needs to be zoomed out beyond 5x to get rid of the dark corners – I tend to use it in combination with a very strong close up lens, to give me extra working distance. Here is an old, but good review of some of the other options you may come across on eBay and in second-hand shops – with a simple step-up or step-down ring can be fitted to the camera - http://www.cs.mtu.edu/​~shene/DigiCam

John,

It's interesting that the website you provide the link to is at Michigan Tech University. It's just 100 miles NW of my town, Marquette. It's actually on a large peninsula sticking out into Lake Superior. My step-son graduated from there. They get lots of snow,nearly twice as much as we do, due to their many opportunities at lake-effect snow storms.

I took some more test shots downtown today to see what the .75x wide lens will do. The results look MUCH better than what I got in the back yard the other day.

Here's a macro shot;

Dennis, I tried a similar shot in macro mode and it did not really work for me, however, with focus set to normal mode it is good enough, with plenty of DoF to cover most subjects. The rest of the shots you have posted look good enough to me, but then again it depends on what you want to do with them.

Bottom line, I have found that the extra mm’s add more value than the slight loss of quality – but it is a personal thing. Of course the other option I have tried is to remove the converter, turn your camera to portrait and then stitch a couple of images together – instant WA, but slightly more time consuming… I am pleased you have some better results!
