I fell and broke my 200-500 Nikon lens in May. Paid $500 to fix it. This time it just slipped right out of my hand. I really like this lens!! But still struggle with enough light even on the Z8. Going to cost another $500 to fix. I would love to go to the z180-600 but hate the idea of 6.3 when I’m already struggling! I shoot mostly low light birds and occasionally low light sports. I prefer the convenience of zoom and don’t want to go with fixed lens. I’d like thoughts on the best way to go. TIA!
What’s the alternative to the 200-500 for low light zoom shooting, Its tough one and the answer is on everyone's wish list.
Rent before you buy may save time money and effort.
There is no silver bullet, well that's affordable, you want zoom and low light, that comes at a cost and compromise, if you have the heart and deep pockets full of cash there are some expensive solutions.
There are some F4 zooms in 200-400, the 100-400 Z is nice but let the MTF charts speak to you. The 100-400 its a good handy lens chronically overpriced for what it is, road test one, you will love the size and weight. But will it be good enough in low light ?
The 200-500 is a excellent tool, the 180 600 is equally good with a whisker of improvements here and there, i hear some say it has a tiny edge on sharpness, i think reading the MTF charts on any glass may help and gauge the % differences. The 180-600 may well have the edge on a Z6III ZF over the Z8 for low light use.
The theory is the newer Z model cameras like the Z6 III, ZF, have 2 more stops of low light focusing capacity 3 more stops of IBIS over the Z8 Z9, this performance difference will no doubt spread into newer models coming. The less number of and larger pixels combined with the IBIS and extra stops focusing in low light could very well be a greater asset over a Z8 for low light performance ? making the 180-600 more tolerable.
Depending on what you exactly shoot, the point being, you may or may not be able to shoot at lower shutter speeds and lower iso that could play your way, just a left field consideration to throw in the mix. Again You may find that the Z6III may well outperform the Z8 in challenging lower light shooting taking the pressure of the limited options in lenses.
Look at the data of your images taken and work on say if 75% of images are in one narrow range or not, you may be surprised and can tolerate a fixed lens in F4, and say if you’re in the 200-300 or 400-500 range mostly then a F2.8 or F4 prime lens may be an option, used ones of course.
Remember you really like the 200-500, try it with a rented Z6III, or even a D5 as a comparison of measure.
