Zoom vs Prime

Thou I already know the difference between a prime lens and zoom lens, I never know the difference is so HUGE. Attached is a direct screen shot, showing 100% view of 2 photos taken at almost the same time. The prime lens is FA77/1.8 @ f/5.6, and the zoom is F70-200/4-5.6 @f/8.

I guess there should be no difficult to tell which photo is by which lens.

A few food shot with FA43

ALthough the new K20D has much improvement over my old istD, I am still not very happy with the white balance of K20D. At AWB, it does not correct the indoor lighting perfectly - something expected and accepted because some photographers may want to retain the atmosphere. However, those pre-set WB does not handle different light source well enough, especially with the yellowish energy-saving bulb and the yellow quartz light bulbs.

In some of the following food shots, I tried a few WB settings in preset WB, but can't get a good result. So I need to reshot in RAW and correct it back home. But I don't always have the luxury of these extra time - the dishes can wait for me to take the picture, but not everything else.

Back from Hokkaido trip

Before the trip, I struggled which lens to bring to the trip. Finally, I decided on DA14, DA21, FA43, FA77 and F70-200. I only used the tele zoom in a few shots, so almost all photos were shot by the prime lens. They are great!! Since the 3 limited lens are very small and handy, I don't feel any extra burden to carry the 4-primes around (yes, I just leave the zoom on the car if I don't feel it necessary).

The trip was with my family and friends, and none of them like photography. So my travel-mates tends to move very very quick, leaving not much time for me to take photos. Complicated with teh bad weather :( :( :( .... I just left my tripod on car and put the camera in P mode. BIG MISTAKE!! The camera will tends to select f/5.6 on those limited lens and the DPF is not quite enough for scenery shots. I really shot leave the camera to AV mode so I will be forced to notice the aperture setting.

While I set the camera to JPEG, I toggled to RAW+ format when I feel needed. However, I didn't notice the RAW+ will be cancelled everytime after the shot, and it created some additional troubles. Yes, I know now there is a setting in the camera to leave the RAW+ format until I cancel it by pressing the RAW button again; but it's a bit late.

I am still selecting the photos, so just post 2 kid shots with my DA21. Very good lens indeed.




Just back from a 8-day trip to Hokkaido.
