カメラの最も重要な側面の1つは、センサーのサイズです。センサーが大きいほど、より多くの光を取り込むことができるため、低照度でのパフォーマンス、ダイナミックレンジ、および一般的な画質が向上します。
多いフォーカスポイントがシーンのどの部分にピントを合わせるかの選択にさらに柔軟性を持たせます。それに画像センサが自動モードでピントを合わせるシーンの場所をもっとよく特定することができます。
メガピクセル数は、メインカメラが撮影できる画像の解像度を表します。メガピクセル数が大きいほど、被写体の細かい部分まで表現できます。しかし、メガピクセル数のみが、高品質の画像を撮影できる要因ではありません。
高いISOレベルが大量の光を取り込み、ピンボケを防ぐ。微光での性能も高くなります。ですが、普段高いISO感度の設定で画質が低くなります
拡張ISOがあると、ネイティブISOを超えることができます。デジタル的に画像出力を高めることで、これが可能となります。結果の画像はネイティブISO範囲内にある時よりも質が落ちますが、特定の状況では役立ちます。
振動ジャイロ機構で手ぶれを感知し、CCDなどのイメージセンサー(撮像素子)を手ぶれに応じて移動させる事によって光軸を正確に当てる方式。メカニカル手ぶれ補正機構ともいわれています。イメージセンサーシフト方式は電子式より優れています。
メカニカルシャッターを使う時に、連続撮影モードで捉えることができる1秒あたりのフレーム数。
オートフォーカストラッキングで、被写体を選択してシャッターを押すと動く被写体を追いかけながらオートフォーカスはピントを合わせ続けます。ピンボケの心配はありません。

Love my D850

It does have an issue that I want to make everyone aware of. First, this camera has a steep learning curve. I bought a book to help me climb the curve a little faster. There are many controls within the camera settings as defined by the software. Second, I've had an issue with the mirror getting stuck in the up position twice. The first time I took it to the dealer and it was repaired in about 15 minutes. The second time I looked through several blogs and found a fix that took about a minute. From what I can tell this is a known issue for newer Nikon DSLR's. If you find yourself in this situation try this fix (worked for me, hope it works for you); -Remove the lens -Look on the left front side of the shutter box and see a small black flat lever sticking out about an eighth of an inch (its spring loaded) -Using your finger gently push this lever down until it stays depressed in the down position -Check for crud on the mirror -Reinstall the lens -Turn the camera on -Depress the shutter button one time Sensor. The D850 functions far beyond expectations in many shooting environments. The combination of available high ISO settings and high resolution sensor allow you to take great pictures in low light that many cameras cannot even contemplate. The high resolution sensor permits extreme cropping and or large prints without pixilation. Weight. It's weight does not lend itself to convenient use while traveling, however, for me, the picture quality makes it worth lugging around. The camera body itself weighs about 2.2 pounds. Adding the battery grip runs it up to about 3 1/2 pounds. With my Sigma 24 to 70 zoom the wait goes up to 5 1/2 pounds. That's a lot to be lugging around your neck but it depends on how bad you want good pictures. The D850 to the Z9; the Z9 weighs .8 lb more. Battery life. The D850 will take approximately 1800 shots on one internal battery. Mirrorless cameras run about 1/3 of that at best. I would really like to go mirrorless but the tech hasn't developed enough to compete with the D850 battery life. Plus I just don't like carrying around a pocket full of batteries to feed my camera. While on this subject I wanna comment on batteries as they relate to the mirror hanging issue. Some owners believe the mirror hang issue is related to battery type, condition, temperature or aftermarket status. I did not find this true in my situation. Knowing what I do would I buy it again, yes.
