What implications come with an AI lens? Anonymous
I'm looking to buy this lens in the picture. Because my budget is low, and I can't afford more expensive macro lenses, I'm settling for this, and I've read that the quality is generally good for the value.

I'm going to buy it from BH:

And the description says it is "for Nikon AI". I don't know this piece of terminology, or what it entails. Will it work with my D50?

Yes, it will work.

However, it only manually focuses, and you may only be able to meter stopped down.

Also that lens sucks and you should just buy a used Nikkor macro for the same price.

it will mount but not meter light. so for digital, its pretty much useless unless you have the time to review each photo on the screen and adjust.

Well then, what kind of macro lens do you guys recommend me to get, other than this? Under $300, if possible.

You could get a used 55 or 105 AI micro for less than $300

not useless. handheld meter get, or just check the first exposure and adjust if light changes in your head.


If you save for another week or two you could get the Tamron AF 90mm macro which is an amazing lens and you wouldn't lose metering, if that's important to you.

Doesn't Sigma make a relatively inexpensive macro lens as well?

Can anyone explain to me why Nikons won't meter with old lenses? I don't see why "Lens isn't smart enough to report its focal length" translates to "ZOMFG I HAS NO GOTS A METER!!!1!" to the camera. Can't it at least do crappy spot metering or something?

Nikon reserves the reverse-compatible metering for the D2-series bodies.

A 50mm or 85mm on even the cheapest of extension tubes makes for a great macro lens if metering isn't a necessity to you.
