Good morning, master. You said: "The newer f/1.8 version would be better as it definitively is NOT a "plastic toy".
I am honored to receive your answer. When you touch and you try to shoot with the Nikon 28mm f/1.8G, it seems to shoot with the Nikkor AF-S 18-55mm DX (or 18-70mm, but there isn't difference for the touch), in my opinion. I think that it's a ridiculos thing that Nikon for a pro prime lens doesn't use metal and it's true first of all for more expensive prime pro lenses, such as AF-S 24mm f/1.4G and 35mm f/1.4G, which are also very expensive!! A photographer who chooses Nikon, professional or amateur (like me) user, don't deserve a PLASTIC bayone, PLASTIC barrel exterior, PLASTIC focus ring. Also if the sharpness is almost excellent, the plastic doesn't ensure constancy and precision for a long time, with a hard use, like a professionist's work use. It's true that today the great brands don't use metal materials as it once was, for commercial reason, I think, but 28/1.8G, 35/1.4G, 24/1.4G are full of plastic, it's absolutely true!!!!! The handfeel when you shoot with one of these lenses and a lens of the '60's years is very different! I'm 40 years old and I shoot from 24 years, with film and mechanic bodies at the beginning (for my great luck!!!), Zenit (no money!!!), Pentax, Minolta SR-T series and Nikon from 2000. I've used old Nikon tanks, indestructible, such as 105mm f/2DC, 135mm f/2DC, 85/1.4D, 80-200mm f/2.8 AF e AF-S (all types), 28-70/2.8, to not speak about AI-S Nikon lenses!!!! Minolta SR-T series lenses, the old Minolta Rokkor MC I serie (for example Rokkor MC 35mm f/1.8, 58mm f/1.4, 135mm f/2.8, 85mm f/1.7, 28mm f/3.5) was pro lenses all-metal. Nikon offends me with a plastic pro prime lens if it wants 1800$ for the 35/1.4G and 2200$ for the 24/1.4G: the plastic doesn't ensure constancy and precision for a long time and there isn't the old wonderful handfeel. Zeiss has continued to produce all-metal lenses: for this reason for the fixes focal from 18mm to 35mm I have choosen Zeiss lenses (and I sold Nikon AF-S 20/1.8, 24/1.4G, 35/1.4G, the 28mm f/1.8G even bought, just tried it in store), for portraits I have choosen Nikon AF-S 105mm f/1.4E G (I need AF) and for street Nikon 70-200mm f/2.8 VRII, and for long trekking pnòy zooms (14-24mm, 24-70mm f/2.8E VRII, 70-200mm f/2.8E VRII FL).
However, the main subject of this topic was to know if in low light conditions, of landscapes and of environmental portrait, Nikon 28mm f/1.4 (another solid glass of a time!!) can give something extra, something wonderful and Zeiss no, it was the reason of its f/1.4 at film era, when ISO was only low (today you could shoot at 3200 ISO without problems and the following shoot at 64 ISO).
Excuse for my English.
