Well ,these flowers are actually much smaller in reality.!! ( The image is not cropped either ) Not sure if , 18-55 will be able to magnify so much. I have taken these shots at a distance of ~1.25mtrs away from the subject at a focal length of 300mm.
I will try a macro shot with 18-55 though. But I am pretty sure , my both lenses are not much good when it comes to sharpness ,( without any editing ).
Next week I am planning to visit nearby showrooms for checking various lenses. I will see a demo of the lens quality and sharpness.
The Canon 18-55 can do even water drops so I'd guess the Sony one too. The trick here is that these lenses should focus really close (~under 10cm away from the lens).
Are you pixel peeping ? Because, while I realise that the primes are definitely sharper, the difference isnt huge by any means and I consider myself to be pretty demanding. Can you share some examples of what you think are poor sharpness ?
You may want to check is its a lack of sharpness or just image out of focus (the beep sounded by the camera is no guarantee that you have good focus) You might want to go Live View mode and use magnify option to get precise focus under Manual focus, and then compare the sharpness.
Yeah , I do magnify the image close enough to see the individual pixels , but they are not that sharp. I will post some samples . You can check to see if the lenses are not that good or whether it's my in-experience in stabilizing and properly focusing the shot.
( I don't use auto-focus in most of the cases , could that be one reason ?? .)
