RiceHigh's Pentax Blog: Comparing the Optics of the Contemporary Giant 85mm Lenses

Comparing the Optics of the Contemporary Giant 85mm Lenses

1. Pentax DFA 85/1.4: 12 elements in 10 groups, 1255g (without hood), 82mm filter thread

2. Canon RF 85/1.2: 12 elements in 10 groups, 1195g, 82mm thread

3. Sigma Art 85/1.4: 14 elements in 12 groups, 1130g, 86mm thread

4. Zeiss Otus 85/1..4: 11 elements in 9 groups, 1200g, 86mm thread

Well, whilst the new Pentax is similar to the Zeiss in design (but with one additional element), it wins in weight amongst the four, which is actually the heaviest 85mm prime ever made on Earth. Good! ;-P

It's design is also very different to the old FA* f/1.4 85mm (IF), which looks more like a simpler version of the Canon lens: https://www.pentaxforums.com/lensreviews/SMC-Pent...

"which is actually the heaviest 85mm prime ever made on Earth"
That's wrong!
The Zeiss ZE Milvus 85mm 1.4 is still the heaviest 85mm prime ever made on Earth!
It's 25g more heavy (1280g) than the D FA* 85mm (1255g): https://www.zeiss.de/consumer-products/fotografie...

And has the second expensive hood ($200) after the Zeiss Otus ($300): https://shop.zeiss.at/photography/product/4047865... https://shop.zeiss.at/product/4047865300407/St-rl...
