Hello,

I just picked up an Olympus Tcon 17 telephoto adapter (1.7x) for my Canon S3is. I've seen many sample shots from this combo so I know they are compatible.

The converter is attached to a 52mm Lensmates adapter tube with a 52-55mm step up ring. I assume this is how many other users of this combo set it up.

My problem is that the camera will not focus beyond the mid point of the zoom range with the tcon 17 attached. I've tried with and without the camera menu teleconverter setting on, macro, super macro, manual focus, etc. It won't even come close to focusing.

Just looking through the tcon, everything looks sharp and clear. Without the tcon, the camera focuses beautifully.

I thought I'd heard some time ago about a bad batch of tcon 17's.........

Anyone else have experience with this camera and teleconverter combo?

Any help is appreciated.

Thanks

If you have an accessories button on your camera, you should try to put it on !!

If I recall correctly, the adapter tube is used mostly on SLR cameras. I think that with yours, you should have the TCON connected directly to the lens.

Does your camera have in the menu anything that mentions convertor settings.. you have to tell some cameras that you added such a lens on for it to compensate

Under the record menu is this option:

Converter - Wide angle or Tele auxilliary lens

You mentioned a tube as well as an adapter ring..*I wish you could send a drawing or picture of the set up. It may be you have some extra distance between the lens elements .. or more space* than the camera can acomodate.

With the TCON17 attached to my Lumix FZ50 ( both of the same thread ) , converter set to TL , cam unable to focus when object is too near , that is less than 3 to 3.5 m away.

Focusiing on far away object no problem at all

Further feedback on this add-on lens appreciated.

This is perfectly normal, that is, not being able to focus on near objects with an add-on lens attached. I have the same situation with my Oly C-730 and B-300 (the predecessor to the TCON-17.) The TCON-17 is a great addition and I trust you're really enjoying the extra reach it provides.

Steve---
The "Conversion" setting for the Olympus TCON-17 accessory lens on Panasonic FZ30 and FZ50 apparently is a holdover from prior models. I have compared the excellent resolution from full 12X Zoom down to the mid-zoom vignette range with and without the Conversion Tele Conversion Setting provided by Panasonic. On enlarged images, I see no difference in resolution.

I find the Panasonic warning message to "set to full zoom" to be a pointless and time consuming annoyance. Other users on this forum report similar experience. The Olympus TCON-17 accesory lens directly attaches to the 55mm thread of the Panasonic FZ30 without adapter and it performs superbly. The tele-conversion setting has no effect on the lens "performance". It merely de-activates some features, such as flash where the lens would intrude on the illuminated field..

The general topic of conversion lenses deserves a knowledgeable technical article with comparative tests. The issues of compatability are confusing to incidental users. Many buy incompatible and inferior lenses for lack of information.

PS
When problems arise, it is useful to consult the user's manual. Every lens and lens combination has a minimum auto-focus distance. The addition of the tele-conversion lens increases the closest autofocus distance substantially. Because of that increased working distance with a tele-converter, over some range of distances the effective magnification with the conversion is less than without. See excellent article "Panasonic DMC-FZ30 User Guide" by Ching-Kuang Shene referenced on this forum.

yeah I agree with Daedalus the tcon17 works perfectly with my FZ50 , you dont need to change any settings on the camera , just screw it on and fire away (obviously only at objects further than 3 meters away surely thats why you have a teleconverter)
