    Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens

    This is the next lens after the 55mm and the first zoom. I really have great hopes for this, as it would make a convenient travel lens. However, there are significant concerns when I compare the ZA zoom with the relatively new Canon EF 24-70mm f/4L IS, particularly filter size. The Sony-Zeiss is cheaper than the Canon by $300.

    Canon:
    Minimum Focus Distance 1.25' (.38 m)
    Magnification 0.21 - 0.7x
    Maximum Reproduction Ratio 1:1.5
    Groups/Elements 12/15
    Diaphragm Blades 9
    Filter Thread Front: 77 mm
    Dimensions (DxL) Approx. 3.28 x 3.66" (83.4 x 93 mm)
    Weight 1.32 lb (600 g)

    Sony Zeiss:

    Minimum Focus Distance 1.31' (40 cm)
    Magnification 0.2x
    Groups/Elements 10/12
    Filter Thread Front: 67 mm
    Dimensions (DxL) Approx. 2.87 x 3.72" (73 x 94.5 mm)
    Weight 15.17 oz (430 g)

    I suspect that vignetting and corner performance will need to be "enhanced" significantly by the Sony A7 or A7r in camera. The lower weight is great, but there is a big difference in filter sizes. The Sony lens barrel is slightly longer and narrower.

    Sorry, but why is the filter size a concern ?
    And what other significant concerns are there ?

    Thank you for the information, always good to keep a close eye on the competition ...

    Kind regards.
