Marc Alhadeff tested four of the new kipo Full Frame and manual focusing E-mount lenses:
Kipon Iberit 24mm F2.4 (review here, order at Amazon US, Amazon DE, Amazon UK):
The Kipon Iberit 24mm F2.4 (350$) is a little bit disappointing : quality issues (decentering) and soft corners are an issue below F5.6.
For a wide angle you will often use it for landscape or street photography and you will need to close to F8-F11 to get good results
On the opposite side you still get the very good color rendition, soft blurry background and excellent sharpness in the centre, so good to be used at F2.4 for small groups or portraits shoot
Consider it as the natural complement to all other Iberit lenses for excellent portraits but not as a generalist 24mm
Kipon Iberit 35mm F2.4 (review here, order at Amazon US, Amazon DE, Amazon UK):
The Kipon Iberit 35mm F2.4 (375$) is a really nice 35 for street photographe and portrait
Like all other Ibertit his strong points are its centre sharpness, its very good color rendition and background blur which makes it ideal for portrait
The Aperture of 2.4 may seems modest but I prefer a very good F2.4 than an average F1.8
Kipon Iberit 50mm F2.4 (review here, order at Amazon US, Amazon DE, Amazon UK):
The Kipon Iberit 50mm F2.4 (325$) is a very good 50mm portrait/street photography lens but not necessary a universal 50mm
The Aperture of 2.4 may seems modest but I prefer a very good F2.4 than an average F1.8
Kipon Iberit 75mm F2.4 (review here, order at Amazon US, Amazon DE, Amazon UK):
The Kipon Iberit 75mm F2.4 is a real gem and a fantastic manual lens for the price (300$)
It is a excellent for portrait and there is currently no other 75mm For Sony E mount
The Aperture of 2.4 may seems modest but I prefer a very good F2.4 than an average F1.8
