 | Pentax D HD FA* 85mm f/1.4 Pros: Sharpness, CA control, quick autofocus, AW, build quality, bokeh, performance in infrared spectrum, negligible coma in extreme corners Cons: weight, size Opinion: I think the best way to review Pentax star lens is to make comparison with another highly regarded one, so this is not scientific comparison of DFA* 85/1.4 and FA* 85/1.4. All images are shot at f1.4, presented in Lightroom and are screenshots. FA* 85/1.4 seems marginally softer at 100 percent magnification, has some kind of glow. https://www.flickr.com/photos/136087193@N07/50096681817/in/datetaken-public/ https://www.flickr.com/photos/136087193@N07/50096681772/in/datetaken-public/ https://www.flickr.com/photos/136087193@N07/50096681977/in/datetaken-public/ FA* 85/1.4 renders out-of-focus background objects a little bit "harsher" if this word could be applicable here. https://www.flickr.com/photos/136087193@N07/50095872548/in/datetaken-public/ But FA*85 has more "blurry" foreground bokeh at f1.4, maybe due to lower contrast. Highlights are more round at the peripheral part of the frame using DFA*85 (could be less mechanical vigneting). https://www.flickr.com/photos/136087193@N07/50096450211/in/datetaken-public/ DFA* 85/1.4 is sharper in the peripheral part of the frame, it seems spherical aberrations are more pronounced in FA* 85. https://www.flickr.com/photos/136087193@N07/50095872673/in/datetaken-public/ FA* 85 has more purple fringing and in case of not very contrast situations that fringing looks like purple glow. https://www.flickr.com/photos/136087193@N07/50095872693/in/datetaken-public/ DFA* 85/1.4 is no doubts better than FA* 85/1.4 wide open if shot against bright sky. 100 percent crop. https://www.flickr.com/photos/136087193@N07/50096681787/in/datetaken-public/ Longitudinal CAs: they are here at f1.4 - more for FA*85, much less for DFA*85. Almost not visible at "normal" view on the monitor screen, but visible at 100 percent magnification. Lateral CAs: I would say NO lateral CAs for DFA*85, but visible for FA*85. Both types of CAs are easy to correct in Lightroom for DFA*85, because at f1.4 the lens is very sharp and has no glow, but difficult to correct for FA* 85. CAs differ in color: DFA*85 has aqua/rose-red CAs, FA* - green/purple. https://www.flickr.com/photos/136087193@N07/50096450076/in/datetaken-public/ According to tests on www.lenstip.com, I would say that just Zeiss Otus 85/1.4 is better in aspect of CAs, https://www.flickr.com/photos/136087193@N07/50095872533/in/datetaken-public/ Sigma Art 85/1.4 and Zeiss Milvus 85/1.4 is on par with DFA*85/1.4. https://www.flickr.com/photos/136087193@N07/50095872688/in/datetaken-public/ https://www.flickr.com/photos/136087193@N07/50095872628/in/datetaken-public/ Other lenses - Sony FE 85/1.4 GM, Canon EF-S 85/1.4 are not bad, https://www.flickr.com/photos/136087193@N07/50096681937/in/datetaken-public/ https://www.flickr.com/photos/136087193@N07/50095872583/in/datetaken-public/ old Sigma 85/1.4 and Nikon Nikkor 85/1.4 G are much worse. https://www.flickr.com/photos/136087193@N07/50095872603/in/datetaken-public/ https://www.flickr.com/photos/136087193@N07/50096450121/in/datetaken-public/ Overall even the lens is heavy it balanses on K-1 very well. It is not much bigger than DFA*50/1.4 if the hood is not attached, but little more thicker. So, Pentax made excellent new optical design lens, that seems on par with Zeiss Otus, but half the price and with autofocus, as well not so chunky (filter thread 82 vs 86 mm). sent on July 21, 2020 |
