Very sharp, relatively inexpensive (compared to 2.8), great build quality.

AF speed somewhat slow for motorsports applications but still very usable, especially with faster-focusing bodies (e.g., F100, F5).

I love mine. It's a great alternative to the expensive, heavy 2.8 (which I may get someday). Beautifully built, very rugged, and fantastic optically. Works very well with the TC14b. An f/4 300 AFS is rumored to be in the works, which would focus faster and would provide AF and matrix metering with the TC14e.

Cheap (compared to other 300mm made by Nikon) but high sharpness.
Light, easy to handle, built-in tripod collar and hood. Accept 39mm filters.

Non D lense and slow AF.

I love this baby ! Couldn't ask for more, since I got this one at almost 1/3 of the high st. price in UK (a good quality used one). Its metallic finish indicates its ability to work under pro condition. Easy to hand hold, trust me. AF speed is just fine for me, no need for AFS since I seldom shoot action/sports.

Light, well-built, compact, inexpensive compared to the f/2.8 version. Good manual focus feel. Nice built-in tripod mount can swivel up out of the way for hand-held shooting. Works very well with the new Kenko Pro 300 1.4x and 2x converters.

AF a little slow, and sometimes hunts (using F4s), I'd like a real lens cap instead of the leather "sack and drawstring" supplied with the lens; it seems to let in a lot of dust.

I consider this lens the longest "amateur" lens in the Nikkor line. Any longer or faster, and you have to pay thousands. This is a very nice lens for under a thousand dollars street price. A serious amateur can usually get by with this lens and a converter for some wildlife shooting.

Four camera bodies, lots of lenses, lots of years, and I never needed any Nikon customer service!

Sharp! Well constructed and very tough lens. I know, I dropped mine and it still works just as good as it ever did!

Early models focused slow. Newer version (which I have) seems to focus very rapidly. I have used it for rodeos and birds in flight.

Great bang for the buck for amateur or professional.

I used to have a Canon 300 with my old Canon system.

Very sharp, works well with a 2X, in spite of being an f4.

No problems have been experienced with any of my Nikon lenses.

This lens has served me well in the field of wildlife photography. I often take just this lens and a 2x with me in the field. If like me you can not afford a 300 f2.8, this lens is an excellant subsatute.

I have tried out some after market zoom lenses (* to 300MM)) none of which was as sharp as the 300MM f4.

Solid Built, Very Sharp, much Sharper than the 300mm f4.5 AIS.

Filter size of 92mm make it difficult for a good filter.I'm using a B&W MCR which cost USD100!

Best alternative if you can't afford the f2.8. In my opinion its optical performance is comparable with the 2.8 if not better except it can't go down to f2.8. One of the sharpest lens I have ever have, Can't reallt beat the F3AF 200mm f3.5 EDIF in terms of sharpness but which other lens can?
Absolutelt vaule for money for a 300mm Lens.

Autofocus lens is extremely sharp even with a telecoverter. Solid construction, drop in filter drawer, built-in shade, wrinkle finish, rotable collar, very well balanced on a monopod.

Aperture setting ring is made of plastic and is exposed on back-end of the lens where it might be easily damaged.

An excellent lens and the best of all the 300 f4s Nikkors I've owned.

Sharp, sharp, sharp.

Doesn't lose anything optically when used with the TC-14b 1.4x (420/5.6). In fact, it may be matched. It's also quite good with the Tamron 1.4x AF-d teleconverter, better, in fact, than the Tokina 400/5.6 AT-X I owned. It's better-than-adequate with the TC-301, which makes for a marginally useful 600/8.

It's great on a short tube.

Even illumination wide open (no light fall-off). Minimal field curvature - in practical use, none to speak of.

Big, heavy, with ponderous autofocus. A focus limiting ring speeds focus by limiting the range in which the lens will hunt. Autofocus is significantly better with my N90s than it was with my N8008s.

Not especially well-balanced or quick-handling when hand-held (but I have small hands).

Uses pricey 82mm filters in front or unique (and equally pricey) 39mm filters in a filter drawer. There is a drop-in circular polarizer available, but it's just as expensive as an 82mm one. For maximum flare resistance, use a multicoated front filter, if any.

Yes, it's big. Yes, it's heavy. Yes, it has slow AF. Yes, it's an old design. Yes, there are plenty of people who say that it's not as sharp as the 300/2.8. And, yes, it has just been replaced by the 300/4 AF-S. Still, its optical performance in the field overshadows all those weaknesses - so much so, that this is one of the few lenses I'm giving five stars in both categories. I can't bring myself to do otherwise; the Nikkor 300/4 ED AF just flat-out delivers the goods.

Great taste of "big glass". Filters get pricey. Try Cokin or Lee. Great with converters. Excellent choice if the 2.8 is out of reach.
