We often hear the claim/argument that legacy lenses are not good enough for digital FF.
Resolution is not there and poor edges being the primary reasons.
In the past, it was hard to confirm and so this passed on from one person to another (becoming a truth in itself).
There is evidence that some of the lenses work well enough since they have been adapted on 5D and 5DII, but these 2 cameras have issues with some lenses (esp. k-mounts) which limit what can be tried out.
But now, with the Sony A7, all the Pentax K-mount lenses can be tried out on a digital FF camera.
So this will be what I will try to do here with all my lenses, spanning M42 > K > M > A >FA and ltds.
I declare this right now too.
THIS IS NOT A
"i'VE JUMPED SHIP AND ALL YOU GUYS HERE ARE SUCKERS!" POST
I have no hate for Pentax (still love it and using it)
THIS IS A
"DOES THE M42 AND K-MOUNT LENS I HAVE WORK REASONABLY WELL ON DIGITAL FF?" THREAD.
I also won't go into promoting the A7 here on a Pentax Forum (leave that to the haters that linger here...
)
Nor will I discuss the camera on this thread (avoid as much as possible)
Its about M42 and K-mount lenses in the FF context.
Photos will all be on my Flickr at full res.
JPG OOC, possibly cropped a bit for composition and/or adjusted for exposure.
AFAIK for now, the Sony in camera JPGS are way overcooked.
Take them as you will, (sorry, I won't provide RAW, too little time and lazy to do all that; and its not about the camera anyway)
(pls be merciful about the poor composition and all that )
Lets start with........
Kiron/Vivitar 28/2 (55mm filter thread; K-mount)
I've not found a hood for this lens that I can directly cap on while not vignetting the corners, so no hood used for the shots.
#1
f2; showing the FOV of 28mm at about 1.5-2m working distance.
#2
f2; 30-50cm away
#3
f2; for small objects
#4
f4;
#5
f5.6
#6
f8
Overall, pretty busy bokeh to me.
No glaringly bad edges or corners.
Sides may be a bit softer, but really slight.
Flare control is not too good imho. (almost a given for non-SMC legacy 3rd party stuff)
Pls review 100% from my flickr.
I really don't have the time to do 100% crops (apologies in advance)
Hope I can go on with all the lenses....
Man! uploading full size picts is so slow.
