Fun with a Sigma 600mm Mirror Lens +TC

I wasn't expecting to get anything out of my very old Sigma 600mm f/8 mirror lens with a 1.5x TC on it, but it's a fun lens to use and I was surprised with a few of the shots that they actually came off moderately OK:



GX10, 900mm (with TC), F8, 1/640s, ISO 400
.
On a tripod, manual focus, manual metering, image cropped and PP (the lapwing was ~60m away)



GX10, 900mm (with TC), F8, 1/400s, ISO 400

On a tripod, manual focus, manual metering, image cropped and PP (the cormorants were ~100m away)

quite good considering the light grasp limitations of the lens..

Does yours fit without a teleconverter in place as I tried one once on my old GX1-L and the "nose" of the flash wouldnt allow it to fit.. but if it will fit the GX 10 without a teleconverter I might get one again.

It fits fine without the TC.
