    500mm lenses, not sure what to get

    The Tamron 200-500 is a fantastic lens , as long as you give it the right lighting conditions . The lens just LOVES good sunshine, and when stopped down to F8 - can get you some great shots . As for that - you need a good lens that could cope with cloudy weather - meaning a fast ' wide open...

    Aperture Vs. Shutter Speed Priority

    I agree with birdman's first sentence - the exposure is what matters . Getting it right means you shot properly . There is no "Law" that says whats right or wrong . Most nature photographists that i know shoot in Av mode, ( while using EV compensation accordingly ) . I use exclusively Manual...

    Sigma 170 - 500mm

    I had this lens for a short while some years ago . It's OK , but not more than that . It's soft at the long edge, and VERY slow to focus . As far as I remeber - it can MF . From my experience - I assume this lens is the most inferior in the zoom group - The Sigma 50-500 , 150-500 , Tamron...

    Sigma 170-500 APO - poor quality lens or is it me?

    I have had the 170-500 in the past, and I now have the Tamron 200-500 . In my hands - the Tamron is far better at all parameters than the 170-500 . There is nothing to compare between the two .

    Do I always need the fastest shutter speed possible?

    If you're shooting stationary birds - then I think you're making a BIG mistake in choosing shutter priority . When choosing shutter priority and aiming fo 1/2500 sec etc ...- you force the camera to open up the aperture in order to get enough light . Therefore - making you DOF very shallow -...
