ealvarez: Is this manual focus lens? $599? I can get 135mm f2L canon for about $600 used and Nikon 180 f2.8D even cheaper used.. I don't share much of the enthusiasm. Maybe I would if I was Sony E-mount shooter.
for anyone who has eyes it is clear that from this test
the Samyang is by far sharper than the Canon. But testing is a delicate matter... also it is performed with old 12MP camera's where 36MP is todays standard. I would like a test with the best 135mm f2 today ; the Carl Zeiss, done by a person that knows how to test lenses.
helltormentor: Does any body know how much the focus throw is? Precise manual focus is achievable if the focus throw is long enough. > 180 degrees
take a good look at the picture... long!
probably a great printer, but i see a problem with 10 ink cartridges of only 14ml..You always are changing them.. they are just too small; meaning that you have to have them all 10 extra just in case ; and the change that one of them is finished while printing is also substantial ; and you can do it again.I have a HP 9180 ( 8 inks of 27 ml)I imagine Canon choose for small tanks to make it cheaper to buy them all...Usually printer do not print borderless with matte papers -there must be a good reason for this...
something else; the center of the lens is frequently better than 36MP. My lenses do 50 +. So in the center you will see the difference clearly between 36 and 22MP. The DXO is giving sharpness one number - border and center altogether...- bottomline: to tell a story with a photograph you may need maybe less dan 1 MP... the cameras are good enough - it is you and me that make the difference...
DXO statistics are crooked:"When comparing the huge volume of data accumulated over measuring 147 lenses, one very surprising result was revealed. The average sharpness scores of the Canon EOS 5D Mark III matched the Nikon D800 and if the results were based solely on the mean average, the Canon actually out-performed the Nikon"-completely not relevant- no information here- misleading-they should have said: You need a very good lens to show that the Nikon sensor is better... if you do that you see Nikon has 39 and Canon 35 ( sigma 1,4 85mm)Well that is obvious at 36MP-
CameraLabTester: Carl Zeiss has picked up on what Nikon and Canon had left open and unkempt: The Manual Focus Territory.
There is a market for real cut MF glass not affected by lightweight lens design required by AF configuration.
Do not forget the Nikon and Canon shift /tilt lenses: these are stellar too- and can do more
HetFotoAtelier: It's a m a z i n g :-)
It seems the magic already disappears at 1600 asa and above.. for sure the d7000 wins in that area
