Well, I do and I don't!
I did that often in my younger day, trying to find out how sharp my newly acquired lenses are; not realising my method was highly unscientific! Ha ha ha... But it was fun and self satisfying ;)
The last time I did that "pointless act" was many many moons ago!
Well, I was at it again today!!
It all came about when the company I work bought a super-duper MEDIUM FORMAT digital camera!
This mega $$$$$ camera pack a whopping BIG sensor with SIXTY MEGA pixel!
Mamiya 645DF, this camera is the same as the Phase One 645DF.
Nikon D800E ;)
After seeing the lens test chart shot by Simon, his visitor claimed that the resolution is so outstanding that even the Nikon D800 cannot match it!
I asked him how did he know, has he done the comparison? He did not but someone "told him"! DUH!!
Mind you, the result from the Mamiya is stunning, the BEST lens test chart shot I ever seen; but I would not say the Nikon D800 cannot match it.
After all, didn't DXO Mark showed the D800 beat a similar Phase One?
That was last week, today I happen to have my OM-D E-M5 and three lenses with me; I was suppose to do a food shot and review for some friends tonight, alas the shoot was cancel... :)
Since the lens test chart is still stuck on our "picture wall", I decided to grab a few quick shots of the chart.
The OM-D is lock onto my Manfrotto carbon fiber tripod, the image stabilizer is turn off. Three lenses was use for the quick test.
First, my 25 year-old Leica 50mm f2 Summicron-M manual focusing prime. f5.6 was used.
Of course I expect the D800 to do it much better!
Just for curiosity sake, what about the "cheap" 14-42 kit lens?
Take a look! The chart was shot at f5.6 and 42mm.
What about my favorite ultra-wide zoom, the fab Panasonic Lumix 7-14?
To the ultra-wide this is how the chart on our picture wall look like ;)
Lets zoom in to the chart, that will be more than 100%!
So what did I learn from this?
Not a lot really! Ha ha ha... that German optical technology is better than most, even 25 years ago!
That all my lenses are practically sharp enough for good photography and forget about shooting test charts!
A little about that lens test chart...
I learned that the only way to measure (ISO standard) resolution of “electronic still imaging” cameras is the 12233 chart. The "real deal" is available only from the International Standards Organization for 116 Swiss Francs the real chart is under copyright protection.
Strangely, the design of the chart is not protected, you can download a printable PDF copy here.
You can be like me and go crazy shooting test charts with all your lenses ;)
A word of warning though...
SHOOTING LENS TEST CHARTS WILL NOT MAKE YOU INTO A BETTER PHOTOGRAPHER!
Happy chart shooting :)
