That has to be CFF (or GPU who makes the lens) - did you pick the 127 or the 160 or the 180? I look forward to your impressions.

Correctly assumed regarding the manufacturer, but much smaller aperture, I'm afraid.

CFF is making a batch of 105 mm f/6 refractors, which are not on their website yet, but some info can be found on the cff_r Yahoo group.

I have one of Roland's 130 mm refractors, but as discussed in another recent thread, while portable enough, it is not exactly grab & go as far as mounting requirements are considered. So something smaller and lighter is warranted, I think.

Expected delivery of the CFF is in June.

Interesting! Thanks for the tip. I hope they manage to build this one a bit lighter than the previous 102 mm f/6.3.

I guess we won't find out until the exact mechanical build is finalized, but I'm told to expect dimensions and weight very close to what the 102 mm f/6.3 was/is. Compared to alternatives such as just about any LZOS lens based mechanical build, the weight appears to be in the same general ballpark, while the AP Traveller and the TEC 110 would appear to be a bit lighter.

I'd call the TEC110 a lot lighter, actually.

If the 4.5 kg I've seen specified as the TEC 110 weight is accurate, then I suppose I have to agree .
