The K1.8 stays a little behind those two, over the whole range not as crispy. At F2.0 and further on the differences are negligible, both lenses perform superb and shine with contrasty and super sharp images between F2.8 and F8. Besides weight, a half stop difference, an even more narrow DOF and smoother bokeh wide open there is very little in between the 1.2 and 1.4. I compared the K50 with my M50 F1.4 and K55 F1.8. This lens is made for object isolation nearby, so this is OK. Wide open nearby objects are rendered nice and sharp, at infinity wide open shots are quit soft and hazy. Using just the viewfinder, 'in-focus' beeps and focus-peaking are not adequate enough, the DOF is extremely narrow nearby. It is also better to shoot in RAW, wide open the RGB-diagram must be adjusted manually at 16 bits to collect all the sensor has caught without having bandings.įocusing wide open must be done in live view and the 8x magnify function, this is very accurate. Be aware you must underexposure in that kind of situations, the standard metering wants to overexpose to daylight but that is not what you want. This is a good lens for what it is, it shines in low contrast evening shots. My copy is quite mint with clear and clean glass in it and everything works as intended. This lens feels like a hand grenade, coupled on a K1 this is a 1.5 kg combo. My very first camera was the black Pentax K2 with the K55 F1.8, I still have that camera and now in 2020 the lens that was made for it is in my cabinet too. Sharpness: 10 Aberrations: 9 Bokeh: 10 Handling: 10 Value: 10 Camera Used: K1iiīesides the K35 F2.0 this one also got on my way. K-build quality, bright, sharp, contrasty The biggest issue may be just finding one to start with.Īn excellently engineered lens. It's expensive but you're paying for top quality. If there was a downside then I don't think I could say it's the price. It's a little heavier than cheaper 50mm lenses for sure, but it's a reassuring weight. On a more artistic note, the way the plain of focus drifts from in focus to out of focus in the photos is so beautiful and subtle. And the bokeh is phenomenal - significantly better than any other lens I have used (really). I have used plenty of what I would call sharp lenses but this is in another league. I found an optically excellent copy with a tiny dink of barrel damage and had to have it.Īfter a few years my biggest observation is the sharpness. I would love to give this lens an in-depth review but I just don't use it often enough for fear of something happening to it! Sharpness: 10 Aberrations: 10 Bokeh: 10 Handling: 10 Value: 10 Camera Used: Pentax MX, Pentax LX Several hoods will fit such as PH-S52 (50mm) and PH-R52. SMC PENTAX 1:1.2/50 (early version), smc PENTAX 1:1.2 50mm (later version) A special gold-plated version was briefly made together with the Gold LX. It was later replaced by an A counterpart. The SMC Pentax 50mm F1.2 is the original version of Pentax's fastest SLR lens.
