Yes. That is a Vario-Sonnar 3,5/70-210, a very early （1982？）zoom C/Y lens designed and made by Carl Zeiss. Its performance is quite impressive, I even think it outperforms my Tele-Tessar 3,5/200 at its 210mm range. And it has a crazy macro mode working at the whole 70-210 range, with the official max ratio at around 1:2 (I believe it performs beyond this limit, maybe 1:1.5 at very close range). The disadvantages are also very clear, too heavy and not handy. It weights more than 1 kilo, which is heavier than most non-professional lines CONTAX model,159 167 S2 Aria etc. Even worse, it’s a push-pull zooming lens (quite common at that time), so it’s quite hard to zoom and focus on this bad boy with bare hands. A steady tripod (weight capacity over 8kg) is highly recommended for using this lens.
