Shooting Wide Angle on A7/A7R

Kanedias

買左A7之後，非常頭痛點張先可以搵到一只Wide Angle 同佢夾。單反Tele-centric Wide angle 當然可以（例如 Contax C／Y Distagon），但系因為重量同外形比較笨重，都覺得係最滿意之選。
系網上不同嘅中英文討論區睇左一輪，似乎以下3支RF鏡都系有共識系夾到A7嘅。

1. VM 21/1.8
2. Elmarit 21/2.8 asph
3. Tri elmar 16-18-21mm f4 asph （WATE）

VM又唔系唔好，但自從試過買VM35/1.2之後，知道自己最後又會心思思想買翻leica，一買一賣，得個吉。Tri-elmar固然想買，但係銀根有限，貴加上又懷疑自己有無機會用嗮3個焦段，買左又驚嗮。

最後買左2號仔。試拍左一日，post一d試拍相。個人覺得紅閘同失光問題唔嚴重，但係無限遠corner smearing 仍然有，大概去到畫面都幾近corner嘅位置。大家可以click入flickr嘅大圖度睇。

如果其他師兄有其他wide angle系A7 或 A7R 嘅相，好歡迎系度一齊jam，咁大家買鏡可以有個參考。順帶一提，無論你覺得好夾或者唔夾都歡迎post，因為我之前做功課時發覺，有好多鏡，有人提過話ok（又或者話後制完ok），其實好難搵到未後制前到底有幾唔掂（例如ZM 18/4 distagon)。

好正咁喎

有無聽過21SEM方面如何？

有需要可能過兩日揾朋友部A7R試下比你。

A7可能難揾sample，好多人賣機upgrade左去A7R。你d相corner smearing就真ok窩，不過red shift唔多肯定，因為得一張colour。第二張就有嚴重失光問題

21SEM 用在A7R會有紅閘，但下載sony 鏡頭補償apps後可以修正。 大部分鏡頭都可以甚至R21F3.4.  值得嘗試﹗﹗

#1277 is great!

To be honest, I never care things about vignetting, red shift & etc...
When a picture is stunning, it's stunning absolutely.

well said!

yes, i think red shift and vignetting are indeed no big deal for me. Coz both of them can be fixed by post-production. However, image smearing is another story. A7 can't even support a mini-wide like 28/2 cron without corner problems.

Dennisony

The "Lens compensation" apps work perfectly for both OOC jepg and raw, not only the correction of peripheral shading but also chromatic aberration and distortion.
Similar to what Leica M9 doing currently, but Leica make preset for you as a list for your selection.

Dennisony

其實Tri-elmar系ng知3個焦段，你系可以當zoom lens甘用， 只不過它有三個定格點咋。好抵用架。。。買啦﹗﹗
