Re: TCON-17 setting on the XZ-1

Hi,

I share your enthusiasm for finding clever solutions that 'beat' the system.

a few comments.

I had an XZ-1, one of the brightest and sharpest lenses I had the pleasure to own and use. Your example, using non-oem 1.5x is not XZ-1 sharp. It makes me wonder how sharp Oly's proper 1.7x tele lens would be comparitively.

I have Oly Stylus 1 (at f2.8 not as sharp as XZ-1 (few are). Stylus 1 is a speck sharper when used at f3.0, but not enough to keep me from using f2.8.

I have and frequently use the OEM Oly TCON 1.7x which is very sharp and maintains the constant f2.8 brightness out to 510mm optical (using 2X yields 1,020mm still f2.8, incredible).

I use Kiwi tube, not OEM, but it's length is specific to the 1.7x lens.

It may be the combination of tube length and 1.5x rather than 1.7x (at that distance in front of the base lens) is not as sharp as using OEM tube LENGTH and OEM 1.7x.

Also, exif: Stylus 1, when you tell the menu which lens is on (1.7x or 0.8x wide), the camera automatically does the 1.7x or 0.8x math, the exif '35mm equivalent' is correct.

Using 1.5x, (any variation) it might be better not to tell the camera's menu, zoom manually to avoid vignette, and later do the 1.5x 'equivalent' math yourself if needed.
