how sharp is your lens?

How sharp is your lens?, people always think their lens in sharp / soft but they didnt realize their lens is actually a soft / sharp lens. Always check it correctly.

OK, im not an optical expert (even though i’m a telecommunication dude doing my degree thesis under Telematic Optic Panel) – but let me show you how i check my lens sharpness.

Take a picture. for example :-
how-sharp-is-your-lens.jpg
This pics has been cropped 10-15% of its original size to 600×402. can you tell it’s a sharp lens? no you shouldn’t

What you should do, crop the picture 100% and observe it. like this :-
100how-sharp-is-your-lens.jpg 

Do you think it’s sharp enough? i think so. The truth is i dont care. If i really want to print pics above without cropping, the picture above would be 1 meter tall. I never print anything larger than 12R before, but to print 1 meter tall print would be overkill for hobbyist like me. imho sharpness is a subjective and art, same goes to bokeh. some might like sharp images but i’ve seen some out of focus and soft images but beautifull. sharp alone wont make a good picture :) – and sharpness depends more on your photographic skill than the number of megapixels.

cheers!

Bro – Adakah sharpness sesuatu gambar tu depends pada total pixels?? I means if 12.5Megapixel file can give more image sharp compare dengan 6.2Megapixel – Am i correct??

no.. definitely not…

unless you want to print a billboard, kalau takat 12R, 6MP will give the same fantastic result as 12MP camera.

kenrockwell write about megapixel myth here:-
http://www.kenrockwell.com/tech/mpmyth.htm

“Image clarity is more dependant on how you shot the photo than on the number of megapixels. A clean shot from a 3MP camera is much better than a slightly out-of focus shot from a $5,000 12 MP camera.”

it’s a good entry to read. :)

Ummm WOW! Stunning images, Jessica!!! Makes my liltte Nikkor 60mm look like a kit lens! I love the dew drops on the rose, the eye of the cat, and your daughter is so incredibly pretty. I can’t wait to see what else you do with this lens!!!
