ジャンクレンズ試写

一昨日(8月1日)入手したジャンクレンズの試写をしてみました。
SIGMA MIRROR ULTRA-TELEPHOTO 500mmF8
SEL30M35+NEX-7
MD ROKKORなどと同じSRマウントのミラーレンズでNEX-7に装着した見た目はかなりデキルヤツっぽいです。

とりあえずお月様を撮ってみた。(下:等倍)

コントラストも解像度も低いのでピント合わせが難しいのなんの。。。
目視ではレンズも綺麗なモンですが本来の性能は出ていないのかもしれません。

参考までにBORG50FLでも撮ってみました。(下:等倍)

BORG50FL+NEX-7
流石にデジボーグと比べたらお話にもなんないです(^_^;)
SIGMA MIRROR ULTRA-TELEPHOTO 500mmF8は焦点距離500mm、BORG50FLは400mmと画角に差があるとはいえF値はどちらも同じF8、にも関わらずシャッタースピードはSIGMAはSS1/60、50FLはSS1/200と大きな差がありました。(どちらもISO100)

明るい内にスズメも撮っておきました。

3枚目を等倍トリミング

解像度が低いわ、コントラストは低いわ、おまけに暗いわで少なくとも手持ちで撮影するにはちょっと無理があるかも?
そもそも全長は50FLでのデジボーグより少し短いですが重量は重いしで見掛け倒し感満載です(^_^;)
でもまぁ遊べましたw


実は昨日はもぅ1本ジャンクレンズを買ってました。
MINOLTA MC TELE ROKKOR300mmF5.6
SEL30M35+NEX-7
このジャンクレンズは外観も前玉もとても綺麗なのですが残念ながら後玉がカビまみれです。

3枚目の等倍
MC TELE ROKKOR300mmF5.6+NEX-7
後玉カビまみれと思えないくらいよく写ってるじゃないですか!
見た感じカビはかなり酷い状態なんですが意外と撮影には大きな影響ないのかな?
こちらは焦点距離300mmの割にそこそこコンパクトで軽いので遊べそう♪
ワンコインレンズ恐るべしです。

  1. ミラーレンズ、巷で噂されている通りですね。
    改めてボーグの偉大さを感じますね。
    ROKKOR300mmは、なかなか写っていますね。
    でも、そのレンズいたの?

    1. ミラーレンズはっていうかこの個体だけの問題かも?
      なんせジャンクですからw

      ROKKORの300mmの方はなかなかなもんでしょう。
      こちらもジャンクで後玉なんて一面カビで真っ白なんですけどね。


      >でも、そのレンズいたの?

      も、もしやこれって!!
      「いたの?」=「要ったの?」
      って事では?!
      それを言ってしまわれましたか?
      望遠レンズはBORGが有るので望遠のオールドレンズなんて使用用途の面での必要性なんてあるハズも無く
      強いて挙げれば利点はコンパクトさですが、それもBORGは分解できるし軽いので可搬性では上を行きますからね。

      無駄と言えば無駄っすねw
      でも趣味の世界では無駄こそ美徳でしょ~
      無駄を否定すると趣味自体の否定にも繋がります。(飛躍し過ぎ)

  11. Superficially, it's hitting all the right boxes, folding in all the improvements and refinements the Droid 2 makes, Motorola seems to have glossed over the camera without much thought. He said -- only partly facetiously -- that one reason they approved farmacia on line so quickly was to insure proper usage of the brand medicine.
