Review on Sony 24-70mm f/4 Vario-Tessar T FE OSS: Full Frame Zoom Lens Review and Features by Seunghyun Nahm ᠌

Sony a7s camera. I shoot through the subject and through his older brother sal 2470z f / 2.8 using the la-ea4 adapter. Pros of the subject: good balance with the camera, easily helps to avoid shake, especially when working with an electronic shutter; compactness for a kit of this level. Disadvantages of the subject: I would like the picture to be better; "buildup" on autofocus (but this is a question for the CAF of the camera). Now about sal2470. The older brother is better in everything: excellent picture, color reproduction, clarity. PPP in the adapter allows the use of mixed AF. Constant aperture 2.8. The real Zeiss! The minus is huge - the weight is about 1.2 kg with an adapter. Conclusion: a7s with sel2470 - travel and events; with sal2470 - studio and all other cases where the weight can be ignored.
