ef lenslerden daha iyi sonuclar alabilirmiyiz manuel lensle...

Çok ortada bir soru aslında bu.
Bu size aldığınız ef veya mf lenslere bağlı. Mesela ef 50mm 1.2 EF aldınız diğer taraftan da Helios 44 aldınız. Kesinlikle Heliosdan daha iyi sonuç alabilirsiniz? Ama Bence siz AF ile başlayın sonra MFye geçiş yapın.
