...計conon一連串走焦..佛光..飛鏡..食塵..直倒無電..散..平..灰..事件..

...經你地大師兄四出明查暗訪..終於水落石出...

...結論係..轉會把啦...

...玩FF..SONY萬能達..平..靚..正..前景GOOD..

...細機用OM 4/3..精品中之精品...

...再唔夠..數背..強!

...1DSMKIII VS OM E-3...

...點解E-3眼位好清濋睇到睫毛...1DSMKIII像素高好多...但睇唔清睫毛...好散...

...40D VS E-3 情况一樣散...

...EOS 5D VS OM E-3

...5D像素高過E-3...CMOS大過E-3...但影(間屋)...E-3景然細緻過5D...

...其實個世界好大...唔好以為L係頂級..只不過中價貨無QC...

...eos中間段最貴支變焦24-70 f2.8L都只不過賣HK$9,XXX-

OM 4/3 中間段最貴支變焦 Zuiko Digital 14-35mm f/2 SWD賣HK$18,XXX-

OM 4/3貴鏡係所有DSLR中最貴...EF L鏡同佢無論價錢同品質上有一大段距離...

...1DSMKIII..用4個像素位先計到一隻色(R,G,G,B)...再斷估插值分拆4個像素位...

...2000萬像素位徐4=實質500萬像素位..再斷估插值X4 ...

...咁好D咩?..

...我部5皮幾1DSMKII & 1DsMKIII走焦..上CS搞好返小小..但好唔晒..

...始終...鏡頭鏡後成像唔係絕對平面(係曲面)...而感光體CCD or CMOS係絕對平面...產生焦平面像差...

...焦平面像差勁...成像散..色瘀..100%放大..永唔知焦點係邊...

...conon解決方法...機內晶片..加色..加利..去信噪...

...GOOD的解決方法...(on 24mmX36mm cmos)..改大鏡頭接環..最小比目前大2-4倍...重新生產改大鏡頭接環新鏡頭.... ... ......=super BIG 4/3

...咁就減小好多鏡頭鏡後成像曲面度...焦平面像差小好多...入光足好多....入射角又直...

...不過..有無人類操作到咁大LOOK鏡頭係另一問題... ... ... ..

...部400D & 40D... 部400D越用越覺手位係設計比E.T用...

...而40D & 400D(aps-c)係用高密度cmos...但佢d鏡(EF-S)..同EF(L)鏡一樣..MTF解像力圖仲用緊10-30線低密度...

...OM4/3..MTF解像力圖用緊20-60線高密度... 4/3Leica..MTF解像力圖用緊20-40線高密度... sigma..同EF(L)鏡一樣..MTF解像力圖仲用緊10-30線低密度...

...EF鏡用落APS-C..有幾唔3唔4係人都知... 24-70L =38.4mm-112mm.... 16-35L = 25.6-56....

...用得conon會有個特徵...不停換鏡...不停換鏡...不停換鏡...但都唔對路...
