I photograph with my Nikon D500. I love!!!
I gave up on my 500mm lens. At this time much too heavy. I photo wild life & mainly birds.
Any suggestion on a lens & maybe a tel -converter?
Many thanks
Without knowing which 500mm lens you had, it's difficult to suggest.
- Nikkor 500mm f/4 FL is currently the largest of them, at just under 7 lb. (and over $10,000 cost).
- Nikkor 500mm f/5.6 "PF" is a new lens with much reduced weight around 3.25 lb. (and a $3600 price tag).
- Nikkor 200-500mm f/5.6 is popular, versatile zoom that weighs about 5 lb. (and costs $1257).
- Nikkor 80-400mm f/4.5-5.6 is another popular zoom, shorter but lighter at 3.5 lb. ($2100).
There also are some third party alternatives:
- Sigma 150-600mm f/5-6.3 "contemporary", 4 lb. ($900).
- Sigma 150-600mm f/5-6.3 "sport" (better sealing, more robust), 6.25 lb. ($1850).
- Sigma 60-600mm f/4.5-6.3 bigger, heavier, but huge range. 5.95 lb. ($2000).
- Tamron SP 150-600mm f/4.5-6.3 "G2", 4.5 lb. ($1200).
Smaller, lighter, but less "reach" alternatives:
- Sigma 100-400mm f/5-6.3, no tripod ring, 2.55 lb. ($800).
- Tamron 100-400mm f/4.5-6.3, 2.45 lb. ($800, optional tripod ring, sold separately).
In most cases, you should avoid a teleconverter except with very high end, top quality lenses. There's loss of light (stops) and loss of image quality with any teleconverter. How much varies depending upon the particular lens/teleconverter combo. A weaker 1.4X teleconverter loses less light (1 stop) and does less "damage" to images, than a 2X teleconverter (2 stops light lost). Most of the above lenses probably won't be able to autofocus on your camera, with a 2X attached. When it comes to image quality, in very generalized terms, teleconverters typically work the worst with lower cost zooms.
