[30sToMars]

我用A300, 前幾個WEEK入左枝SIGMA 70-300, 今晚見過月亮又圓又光, 用點測光 300mm MARCO影, 但我想問下有咩方法可以用盡300MM & 1:2個放大率? 我宜家就咁影前面既鏡筒只係申出一半, 用MF又對唔到焦

[fung614]

小弟愚見
marco係指可以有更近既對焦距離
呢枝好似係1m以下

影近野先至會有1:2既大細
影月亮呢的咁遠既唔會有

如果係影月亮......1:2=.=""即係............
你ccd上既影像,係月亮既一半大少.........
即係.........1:2影晒個月亮既話
你既ccd面積要等於.......月亮面積既一半.........

影月亮用MF對M mode可能會比更容易

哦, 明白晒喇!!唔該晒ching!!

我琴晚用a mode都影到, 但起部機放大個月就唔太清楚, 係咪正常?

[fung614]

唔太清楚,係指好唔掂果隻,
定抑或係唔中焦果的?
或者係,枝鏡唔夠利?

af可能對得唔夠好
(我用長kit,所以...真係唔多好)
因為,其實月亮都ok暗
最好mf慢慢調(當然....好煩下......)

btw....我只有平鏡架咋,
所以放大唔清,我實係既...................

另外,
a mode的話,可以試下唔同光圈,
會有唔同既效果
例如想影埋的雲彩,可以用大光圈
如果,想要得個月光,可以試下細光圈

I use kit len also, and the moon is not sharp when I crop.
Really wish to share with you the moon photo compare if my skill problem or not!
For 細光圈, infinity foucs will have to get sharper or not? I guess not and so never try... but seem I am wrong... please teach me more on that, thanks!!!

[fung614]

其實=.=我都唔係好掂既

係影月亮呢處,我用唔同光圈大細唔係為左sharp,
kit鏡,sharp機有限,而且我好少開100去睇既,
不過月亮,我都會crop下佢

下面既,係我用mf對既,可惜,a350個vf太細,
lv做mf放大又好唔得,影左幾次,差唔多就算
所以,焦點唔係太好=.="".......

F5.6 (呢張想影埋的雲既)


F45 (好極端,呢幅唔中焦=.="")


光圈唔係收到最細會最sharp,
但每枝鏡最利既,都唔係最大既光圈
但係=.=""利呢下野,唔多理架我
所以,一直都係用kit鏡算.................

至於infinity foucs 呢樣野.......
infinity係指對焦個object既距離
所以,月亮,當然會對到去inf啦..........

Thanks for sharing.

With to have chance with other sony user take photos and borrow their lens to try...

我都好想買支長鏡影月亮，因為見人影到連啲窿窿都好清楚好鬼正！

呢張係用a700加支55200（放部a350時留番呢支自用）影嘅（Crop圖），200（300）mm冇辦法影得更清楚，見笑…

I try 300mmkit len with very good wealther also but no sharp as this post.
Really not sure if this is related to A200 or the 300mm kit len.

Really need to find out later.

After reading your discussions, please let me suggest something additional:

1. try different white balance setting;
2. use high ISO speed, & high shutter speed; and
3. use tripod.

我喱一張都係Sigma 70-300mm F4-5.6 APO DG Macro用Nikon D70影，600萬像素，cropping factor 1:1。
