不知道有沒有人像我醬無聊??

某天將D70機身轉一轉(類似橫拍.直拍醬轉),

會聽到像機械表的轉子聲(很小聲.耳朵很近就聽的到).蠻好奇的,不知哪位大大

知道是啥^^

This are my observations comparing the Nikon 80-200 I own and the Sigma 70-200 that I had for a month to compare side-by-side. Others may have different experiences.

The 80-200 2.8 is better optically. Wide open the Nikon is sharper and has More accurate color across the board. By 4.0 the difference in sharpness is negligable. Some my have Sigma lens copies they say are as good wide open as the Nikon...who knows? Sigma had constant problems focusing accurately in low contrast situations, even in good light. This was a BIG deal for me. Nikon always locked focus in the same situation. The Sigma focuses a bit faster but the Nikon is no slouch. Nikon 80-200 and Nikon 70-200 VR are optically the same quality wise. I tested them both side-by-side.

All I know is this:
My Nikon 80-200 is sharper wide open than my Sigma was.

Nikon was much better getting an accurate focus lock in low contrast lighting. Sigma would get a focus lock, but it was not focused on the intended target. Seemed it always went for the next highest contrast subject in its field of view.

Nikon has accurate color and good contrast, Sigma has a yellow cast to the pics
Sigma focuses a little faster. than the Nikon.

Decide for yourself what is most important. For me it was sharpness at 2.8 -4 as I shoot lots of sports in low light. An accurate focus lock in low contrast lighting is also a must. Sigma couldn"t do it. Makes the Sigma an expensive 4.0 lens for me. I returned the Sigma after a month.

基本上我很少會加CPL拍照的.....
可能我用的是KENKO的CPL的關係...
感覺上沒啥效果且畫值會變差...
我之前去南投玩的拍照的感想是..
已是否能拍出很藍的天空講...環境就佔了很大個因素..
在高山的晴天少了空氣污染...隨便拍都很藍...
在海拔就低的地方...加了CPL還是沒有很大的效果..
這是我個人的感覺啦...如果有誤還請各位大大指正..

小弟終於進入D70家族了.先來向各位前輩拜碼頭.請大大們多多指教.

D70 讚..讚..讚..

創見1G 約NT:2K多...

請問內閃出力是否只有在auto mode 中才有fill-in ？
小弟常用A mode，常要調整內閃出力。
D70 匹配的閃燈中，SB600 與Sigma super 500，各位推薦哪一款？
Metz 也有幾支，但規格我看的頭昏眼花。
這幾支都有離機無線遙控的功能，是否就是以內閃同步觸發？

如要離機有線i-ttl(or d-ttl) ，需要什麼配備？
D70 支援的閃燈功能與D2H、D2X 一樣嗎？我現在還搞不清楚command mode 是啥咚咚？需要有匹配的閃燈才有動作？
