Can someone tell me what I will REALLY be losing by using a 1.8 AF Nikon lens without D...vs. the 1.4 AF Nikon that does have the D? How will it affect my flash or available light exposures and metering? I've gotten conflicting advice. Thanks
The "D" stands for distance information that will be read through your lens. Your exposure in any programmed mode by a combination of distance from your subject and the metered light with most new nikon cameras. The 1.4D costs a little more but, the sharpness and detail it will give to your subjects is unbeatable. I would have a newer nikon and buy an AF lens that wasn't "D" compatible at least.
Thanks, Scott...the guy at the camera store said something about flash exposures being more accurate as distance measurements via the lens are communicated to the flash output...but I agree that no one has been able to show me any real proof...
The most noticeable difference I have noted with D lenses is when photographing a small subject (such as full length shot of a small child) with a background that is far away. In that situation the distance information communicated by the D lens keeps the subject from getting overexposed.
The Real Difference is more than the D switch, or the build quality, it's the lens construction. The 1.4 has 7 elements in 6 groups, the 1.8 has 6 elements in 5 groups. Also, the majority, if not all of elements are much larger in the 1.4. This lens is great for hand holding in available light, where every half or 2/3 stop matters. It is the fastest new Nikon AF lens that normal people can afford.
I will post tomorrow some pictures I took at Notre Dame de Paris a couple of days ago without flash!. I just got back, it is 2 am at home and I am spent. You'll get to see the difference tomorrow. Nice to be back. Have a great time JRP My profile Previous photography stuff, before Nikonians: A Brief Love Story
This was taken with the 50mm f/1.4D on a F5 with Fuji Superia X-tra 800 at the Sacre Coeur de Paris last weekend, existing light (no flash), very likely at f/1.4 to keep it steady at a reasonable shutter speed of no less than 1/60.
For all of the slow zoom folks, the f/1.4 at the minimum safe handholdable speed of 1/60th equates to f/4.0( average zoom's speed at 50mm) and 1/8th of a second. Also don't believe that the dinky flash will do the job here... it will fall off to nothing before it touches the steps, much less the pillars.
As a minimum, everyone that wishes to be viable in as many situations as possible should at least get that f/1.8 50mm lens for a hundred dollars,and keep it in the bag... f/1.8 at 1/45th is still a better chance at a great picture like this one. If you have the means, f/1.4 is even better, but the f1.8 lens still beats the zoom by over two stops.
Great shot JRP. I know I won't be getting rid of my fast glass anytime soon... shots like this remind me of why I have them.
Thanks guys: Glad you liked that shot under extreme low light with the 50mm f/1.4D. This other one I looked to shoot at no less than f/5.6 so speed must have been about 1/30th; late afternoon, early evening, no sun at Le Jardin du Les Tulieries (between the Louvre and La Place Concorde) with the F5, Fuji Superia X-TRA 800. Considering not just my advanced age but my low physical condition and the shivering cold wind it is amazing it came out with respectable sharpness. I am glad I bought it for this trip. I had a great 50mm MF f/1.4 but it went away with my donated Nikomats (I must have really liked that friend). Glad I sort of replaced that gorgeous lens. It will always be in my bag.
I don´t think I would have made it with the 35-70mm f/2.8D, the lens is heavier and bulkier. Not to mention the AF-S 17-35mm f/2.8D ED IF or any of the other bigger guns I took with me. Have a great time JRP My profile Previous photography stuff, before Nikonians: A Brief Love Story
As far as image sharpness is concerned none. I have the 50 1.8 cost me under $100.00 new & it has turned out to be the sharpest lens I own. Doesn't have the magic d chip but this is not a concern unless you are using flash & even then the end results are hardly noticeable. Built quality favors the 1.4 & the slightly faster lens opening however all things considered the 1.8 is a great lens for the money. Another thing if you loose it or drop it it's not a major money loss.
