My intention to buy the Pentax K7 did not materialised, I bought a Canon EOS 60D instead. What made me be swayed over to this camera was the high definition full 1080p video recording plus stereo recording if an external microphone is used and the 18 megapixels sensor. The video recording of the Pentax K7 is not really a true high definition, just a little bit short of full HD spec. However, I will be missing the HDR recording capability of the K7 and the Pentax K mount lenses that I had, especially the primes. I am very fond of the 135mm tele lens. It’s very sharp. Many of the 135mm lenses are of 4 elements in 4 groups. That’s practically the minimun amount of lenses found in any lens group.
The camera came with an EFS 18-55mm IS zoom kit lens. My view about this lens is that the sharpness of the image produced is just OK especially in bright lights, but left much to be desired. I need a prime lens. So when I read about the cheap 50mm 1.8 Canon AF lens (plastic body), without much hesitation I went out and get one plus a Kenko C-AF 1.4X Teleplus Pro 300 extender. I do not think that extender or teleconverter in the range of 2X or more is good in maintaining sharpness. 1.7X should be OK.
After shooting around for a while with the camera, I cannot help but felt that the small frame sensor of the Canon 60D, or any camera of this type, is not quite on par with the 35mm film camera in image sharpness. I had tried various methods, daylight, flashlight, twilight except for moonlight. I even bought an adaptor to use my Takumar 135mm tele lens. It is sharp but not as sharp as in the film print. Maybe I am missing something. Manual focusing did not help either, probably I need to change the focusing screen. The AF lenses of today are not like manual lenses of yesteryears where you have aperture and distance markings to give you a rough guide on depth-of-field. Maybe top-of-the-line lenses have it. I have yet to have a hands-on on a full frame DSLR. I won’t be buying it because the price is too prohibitive right now unless I am making moolah out of it, but I am sure would like to try it out somehow.
Reading reviews about Canon lenses or lenses for Canon EOS, I found out that many reviewers failed to mention the material of the lens for the lenses they reviewed, whether it is glass or plastic. These are for entry-level and mid-level lenses, as for the top-level or pro lenses it goes without saying that they should be all glass. They only mentioned the built quality, how good or bad it is and the tests results. I could not help but felt that the Canon EFS 18-55mm IS kit lens is not only having plastic body but the lenses too. It’s too light for the lenses to be made of glass. Then again I could be wrong. The advantage of glass lens is that it is more scratch resistant.
The camera system of today is now fully electronics. It is in fact a computer specialising in digital imaging. They are made of plastic in many ways yet in my view they are not cheap. I did not meant the consumer level point-and-shoot cameras but cameras for hobbyists, amateurs and serious amateurs (or semi pros). These are cameras for entry-level and mid-levels segments. The top-level DSLRs seem to be out of reach unless you have deep pocket or money to throw away or you are making lots of money with it or…you get it for free. The only good side of it is that once you have a DSLR camera that have a manual setting, learning photography is now very cheap. You can snap, shoot till you run out of memory. Still, you can delete and shoot again. In film photography, every exposure counts, because it does cost money to buy and have the film developed and once exposed, there is no return. No delete, nada. If it turned out good, good then. If it turned out bad, too bad but still you learnt.
