Summary: I had two n90s Nikons. I used these primarily to photograph at Figure Skating shows, with low available light and constantly changing light. I bought the MF-26 back for both of them, which provides a little trick called "Focus Priority". This means that when you click the shutter, the camera waits the very small interval it took to get in Focus with the skaters "who were moving targets", before it would activate the shutter.
Pros: Very Fast Autofocus, Great Meter, Great Flash Camera, Very Good in low light, Great MF-26 Back
Summary: I hate to say I sold my F3 and bought a N90. I liked the idea of fast focusing with Auto Focus lens. This camera was junk from the beginning. Focus was slow and searched all of the time. Nothing like my F4s! The meter was junk as well. I sold this boat anchor as soon as I could and upgraded to the Nkon F5, The F5 was just a Nikon F4s with dial instead of dials and the F4s metered with my older lens which the F5 wouldn't without sending it into Nikon.
Pros: It's a well buildt Nikon.
Cons: It's a boat anchor., Slow searching auto focus even with high contrast and great lighting., Terrible results on film even with a sturdy tripod., Couldn't wait to sell it.
Summary: The Nikon N90S/F90X is as advanced as any film camera needs to be. You can get more bells and whistles on an F100 or F5 or F6; but all you really need is on the 90. It has fast autofocus, matrix metering, rapid motor drive, and top-level flash capabilities. You can add more features by adding a special back; but that would complicate unnecessarily an easy to use machine.
Pros: Strong construction and weatherproofing, Fast AF, Superb and flexible metering, Fast motor drive, Extended flash capabilities, Low price for used examples
Cons: It doesn't have mirror lockup, A special coating on the back wears off of some early units, You can't take it with you when you die
Summary: The Nikon N90S is an excellent camera. The controls are easy to operate, and I have had excellent results using both manual settings and program settings. The camera feels comfortable in my hands, and the controls are in good positions. I have used this camera in many different weather conditions and have NEVER had a problem. The extra money required to buy Nikon products seems to be a good investment as trade-in or trade-up values are high. I love my camera.
Pros: Flexible options, excellent quality
Cons: accessories to access some camera capabilities are expensive
Summary: Nikon's N90s has been on the market a few years. The newer F100 and F5 offer more features (at higher prices). When the F100 was introduced the N90s became significantly less expensive, and consequently a better value. It now offers a great set of features for the money. The Nikon lens lineup is extensive, and the N90s can use most of the older (manual focus) Nikkor lenses in addition to the new autofocus lenses.
Summary: The ability of this camera to focus just the way you want it is uncanny. It can focus through miniblinds to the image beyond. It integrates the optional flash to the onboard computer linking zoom, focus distance and using multi-segment measurements to perform TTL on the most likely subject. It attempts to operate in fill-flash mode as good as a carefully metered shot when fast shooting. It's surprisingly easy to operate and understand for the sophistication it has.
Excerpt: I have been using this camera for 10 years and it is a great value workhorse with just enough technical options to create great photos but not making the camera difficult to use. This camera does not come with a built in flash but supports the Nikon flashes with fast shutter support. If, like me, you couldnt afford the f5 or f100 this is the baby for you.
