So what alternatives do we have? How do we capture that Alpine Accentor in the high Himalayas with affordable equipment?
|Sigma 150-500 F5.6-6.3 $899|
|Tamron 150-600 F5-6.3 $1069|
|Nikon 80-400 F4.5-5.6 VR $1995 street|
|Canon 100-400 f4.5-5.6L $1699|
|Nikon 300 F4 AFS ED $1369 street|
|Canon 300 F4L $1449|
As you can see I personally prefer the primes with a tele converter to the long zooms - this is also because I usually have a lens like the 80-200 f2.8 or 70-200 F4 Nikon in my bag when shooting wildlife! On the flip side if you have one body only you need to change lenses and dong this you may often miss the shot!
Essentially you need to weight up what your needs are at a price point which you can afford and then make the correct decision! Good luck!
