想知道这些差距是不是因为焦段不同造成的
毕竟差了10mm 如果30mm镜头成像估计会更清晰

The lack of AF may be a little tricky on the Samyang 85mm f/1.4 but this is
basically a non-issue on the 8mm f/3.5 Fisheye due to the immense depth-of-
field provided by such a lens - for most scenes just set the focus distance
to 2m and then be happy ever after. If in doubt (e.g. in very close focus
situations) you can, of course, use Live-View to fine-tune the focus
manually. Setting the (working) aperture directly on the lens may also be
something to get used to but it's really an acceptable compromise here.
The Samyang is a fisheye lens and as such the extreme amount of barrel
distortion is actually a feature and not a bug. However, the Samyang is
still a fairly unusual fisheye - it has a near-"stereographic" projection so
its distortion characteristic is actually less extreme at the image borders
compared to conventional fisheye lenses. It's the first of its kind and
Samyang even filed a patent for the design.

其实鱼眼比广角更容易做锐吧?

不用纠结了
凤凰确实比三阳锐
看来新镜头不一定比老镜头好

算了 就一百刀收的也不是很贵
这样我的焦段就差不多齐了
现在包包里有8mm, 19-35mm, 28-70mm, 55-210mm
