I'm surprised that the Sony 50mm outperform the Zeiss 24mm. I'm not convinced this is the case in real world shooting of these two lenses. Although mechanically its probably easier to make a good 50 than a good 24. I was shooting with someone who had the Sony while I was using the Zeiss and I had better light transmission...I don't believe he was using a filter and I was. Regardless, thank you for the above review.
Please add the SLR Magic Hyperprime 50mm f0.95 to the review list.
