Question: Best low-light lens for Nikon D80?

bollockovnikov — Wed, 10 Dec 2008 05:03:51 -0800

I am looking for a lens for my Nikon D80 that works well in low-light conditions. Something relatively compact and not too expensive would be best.

I already own a 18-200mm VR lens, which is OK in low light, but not very compact.

I would obviously like my new lens to be useful in a range of situations, but I am more interested in the portrait to 10 metres range.

I do not own a flash unit and don't intend to buy one.

Thanks

A 50mm 1.8 is around $100 on the used market. Among the most compact lenses made for Nikon. It also has a reputation for great sharpness.

An 85mm 1.8 would be about $300. It's a bit bigger, but still much smaller than your 18-200. More telephoto. Probably best for that 7-10 metre range. (Though the subject is still a bit far for that lens I'd think. If it's really that distance you're working with, a 105 might be they way to go. They're more expensive, probably beyond what you're looking to spend.)

There's a 35mm f2, slightly slower, about $200. Not a fantastic portrait lens.

F1.8 is two full stops faster than F3.5, which is where the 18-200 starts. That's a four times faster shutterspeed, say 1/250 instead of 1/60, or one quarter of iso. (i.e. if the shutter speed stays the same, your iso is 400 instead of 1600).

A nifty fifty. The quality/price ratio cannot be beat.

Thirding the plastic fantastic. Everyone that I've recommended the 50mm 1.8 to (Canon and Nikon users alike) has fallen in love with it. If you have a bit more in your budget, the upgrade to a 50mm 1.4 is completely worth it. I never take mine off.

If you're buying used, I highly advise using KEH Camera. They have the most reliable grading system for second-hand equipment of just about any dealer, including the biggies like Adorama and B&H.

Their navigation menu is a little crappy. Here is a list of their prime auto-focus Nikkor glass. You can get a 28mm f/2.8 for ~$125 or the 50mm f/1.8 for ~$100. If you want to spend another $100, you add the 24mm f/2.8 and the 85mm f/1.8 to the mix--the latter of which is one kick-ass, take-names lens.

I don't work for KEH, I'm just a satisfied customer.

For portraits on a D80, you will be fine with a 50mm lens. The 50mm 1.8 is a great starting point, and the 1.4 is just an amazing lens.

Nthing the 50mm. Although now that I have a 24mm 2.8, I've been using the fifty less. Either way, you'll get the intended effect.

A good place to buy cheap/second hand in the UK (except ebay). I reckon I will get a 50mm 1.4

I buckled and bought a 50mm 1.4D from a reputable Hong Kong seller. Including postage, to the UK, the lens was £189. Can't wait to use it. Thanks for your help!

in image quality terms I understood it was slightly inferior across all stops to the f1.8

That's the commonly-held wisdom (I'm a subscriber to it, as well). Not to mention, your depth-of-field shooting f/1.4 at a subject 10 ft. away is 8 inches. At 5 ft., it's two inches. At the minimum focusing range of that lens, your DOF is 3mm! (Thanks, online depth-of-field calculator!)

But there's one really good excuse for the 50mm f/1.4: the fact that there isn't anything faster (or equally as fast) for anything near the same price. The extra cost over the f/1.8 might be worth it just to never have to say to yourself, "if I only had some faster glass..."

I've tended to buy and use 50/f1.4's over 50/f1.8's over the years only because some of my clients are easily impressed by the larger piece of glass on the front of the f/1.4's.

The real world percentage of photographers who legitimately need the extra speed or other optical characteristics of the faster lens is minuscule.

Optically and mechanically, virtually any Nikon 50/f1.8 or 50/f1.4 lens, current production or 30 years old, ever produced, is going to net you superior optical performance to your 18-200 (which is not a terrible lens at all).

I've been asking myself whether the 50mm f1.4 is a worthy upgrade to the 50mm f1.8, but in image quality terms I understood it was slightly inferior across all stops to the f1.8. And it is only a stop faster, which with modern DSLRs' low noise and high sensitivity seems hard to justify.

The 1.8 will produce sharper images, it will do so for less money, and is easier to work with. But that doesn't take away from what you can do with the 1.4 Take a look at the pool over at flickr. Some of the images show off the unique feel of the 1.4. The Leica Noctilux is much less sharp than the 1.8, but it too has a unique feel.

What really makes fast lenses interesting is that they change the expressive space you work in. Modern lenses are typically all about sharpness. Fast lenses aren't about sharpness at all. They are about bending the rules to let just a little more light in. Try one out, you might really like it.

I use both a Nikkor 28mm 2.8 (sharp, tiny) and a Sigma 30mm 1.4 (soft, heavy & huge) on my d70. When I bought a used MF 50mm 1.4 (soft, big), I found the blades were oily, so it doesn't really work anywhere other than 1.4. But that doesn't impact my use of the lens at all. I'll probably buy a 50mm 1.8 (sharp, tiny, cheap) rather than have the 1.4 fixed. I can't meter with the 50mm 1.4 on my d70 either, but it isn't any trouble to bracket until I get the exposure right.
