嘩,又有新玩具,點解得咁少相,快D試多D支鏡好唔好。
AF快唔快?Set manually,即Manual mode?
作者: passerby-b    時間: 2018-2-1 14:04

冇雀咪少相LOR
係用M MODE,AUTO ISO 影的,EV compensation 就自己調﹗當時SET錯咗,爆晒﹗好在PS番,A6500 Latitude 真係唔錯
AF唔夠7DII 加大白II快,但係又係嗰句,準好多LOR
今個星期會再試A6500加856,因為始於D個combination至會最多用,
夏天會用A6500+100-400G 影蝴蝶,睇吓又咩效果
作者: hooooon    時間: 2018-2-1 17:20

A6500+856對焦速度可以嗎?
我用在684就要搵一陣才對到焦,有點慢,如果下下用手對焦,又不太習慣。
作者: passerby-b    時間: 2018-2-1 21:42

A6500+856 都係要下下手對焦先,然後auto至會快﹗
有時係咁都對唔到,所以要諗下留唔留番架7dii!

要唔要試下A9 或A7RIII?

引述:

FYI...I picked up the Metabones 5 and the A7RIII. Tested this with the Canon 600mm f/4 II with and without the Canon 1.4x TC in single-shot focus, the autofocus is too slow for my taste. If you are already close to the focus point, it's not too bad, but when the focus has to travel far, it takes forever to find focus. Once it does focus, the image quality is wonderful, but getting there is the battle.

Attempting to achieve focus in continuous focus is a lesson in futility.

If I had a bird perched in a tree...yup you can do that.

BIF? So far from what I have tried, not usable.

I may try the MC-11 but don't hold much hope.

解決了我的疑惑,我可專心用DSLR為主。
作者: passerby-b    時間: 2018-2-2 21:28

Exactly, this is what I had experienced with the Metabones 5.  Subjected to what birds you are going to shot.  The A6500+856 could still a very good choice.  I am not sure whether I should sell my 7D2.  It is really a mess.  Especially for AF accuracy.  1DX II could be better, but giving the price tag, an A6500 + adapter is worth of it.

回復 9# hooooon
after yesterday's test for the combination of sony cameras on Canon 856 in Tai Po Kau under the exactly same condition as last week, I ruled out the possibility of using the Sony cameras as the main camera with the Metabone 5 in the future of birding in forest environment.  It was simply useless.  The combination just could not focus a single shoot at a bird.

I got my MC-11 upgraded to the latest firmware today and may try it out this weekend .  

Nevertheless, I took the 7D2 to Canon for a full health check and it may return to me after the lunar new year

攞7D2去check,要幾錢?有冇嗎?

我睇雞能真係賺夠啦﹗
本來想保存佢一點名聲,你問到,真係且哂火﹗
我去話我想check 下個shutter 打了幾多野,佢話先生,我地冇d個服務架﹗
下﹗你地唔係話7d2 有 150,000下shutter架咩(d個我記錯,係200,000至真)?我想知,我使唔使換shutter,我要去個trip,受唔起個shutter中途壞架﹗
佢睇下架機,話有花痕喎,個樣好似話,架機咁舊,換新機啦咁﹗
跟住話,我地最多同你check下,個shutter衣家有冇事架咋﹗我地講唔到將來點架(我頂,我鬼唔知今日取個老婆,聽日就可以走佬咩﹗咁你地講乜x有幾多下shutter durability 呀﹗)
好,咁你幫我再check下,個focus有冇事,我影隻雀,十零米遠,十張有九張唔中焦,乜事呀?我上次來check,就係影唔到飛鳥,同一日同一枝鏡,用5d3就影到,你地咪又話冇事。
我仲寸佢,我用個adapter,用索尼機,中焦機會仲大過架7d2﹗佢好似do哂嘴﹗喂,你d product 咋,唔好唔開心喎﹗
跟住唸書咁同我收3舊check機費,如果換shutter要收1400架。
我x,有長鏡,第一時間掉x哂佢d野

哈,一肚氣的官腔,完全唔想接工作,可能你太pro,人哋唔知點招呼你。
我如果再揀,我也唔揀Canon,相機總係覺得落後。

呢張真的發揮到Sony機和GM鏡的威力,好有立體感!
作者: hooooon    時間: 2018-3-2 18:27

不如諗多一諗,Sony A7III,用左A9對焦系統,又有Full Frame,如要crop,又可以即時用機身crop sensor功能。我估,對焦會更快和準!
作者: passerby-b    時間: 2018-3-2 21:38

唔知a7iii,a7riii 同 a9 和 a6500 對焦分別有多大.
a6500 + sel100400 gm,影蝶有一個致命的問題,遲d 有時間,我會上去sony問下。
問題係,100400 係冇clutch ge (雞能d鏡頭就有),即係話,sony 唔可以用手去搵到隻蝶的大約對焦位,跟住用auto focus 對準,d 樣影蝶好重要,因為係微距世界,隻蝶前後爭d,focus可以out好多,D鏡自動對焦,經常要行哂起碼一次整個對焦範圍,至搵到隻蝶,再對準焦,其實往往係慢過用手搵到隻蝶,再用AUto 對焦。
sel100400 + a6500,因為冇clutch,所以,手動先搵蝶,再對焦已經冇可能,更壞的還在後頭﹗
唔知點解,隻蝶飛近相機,你要對近時,系統總會對到後面的花草,橫枝等,就算明明在前面的蝶,佔了多數的畫面,也是這樣﹗
又唔可以手動,自動就去左後面﹗咁點攪呢?
我只有搵個更近的object,對左先,然後再去搵隻蝶﹗
結果,就係好多時隻蝶都走左lu﹗
雞能d機,可以調先對前景的對焦方法,a6500好像就沒有了,唔知其他model 有冇

真係唔用唔知,支鏡對焦上可能要有得update firmware至有得搞,暫時只有Sigma鏡有,Sony可能當作bug了。
可能用Sigma MC-11駁大白II表現仲好。
