D3100 used lenses suggestments for Kruger Park

[Sbiriguda]

Hello,
I will be in Kruger in South Africa this May and I would need to change almost my photo gear but I am on budget because I spent quite a lot for the trip. Right now I have:

a) Nikon D3100 (quite obsoleted, I know)
b) Nikkor Zoom Lens 18-55mm f/3.5-5.6 Auto Focus-S
c) Canon Powershot SX60HS

I am considering to buy second hand lenses for the D3100 in particular 100-400, they should be a good compromise both for price reasons and encumbrance. For birding 150-600 would be better

1) Can you suggest me second hand 100-400 lenses around 300 or 400 EUR?
2) Would it make sense to buy second hand 150-600 and resell them after the trip? Is it easy to resell this kind of lenses or would it take long time and effort?
3) Should I consider Sigma 50 500 OS or similar? Are they heavy to carry?

Thank you

What would you be shooting ?? Wildlife? Safari ? Or just generally everything ?

I would have thought if looked after on your trip you could easily buy a 150-600 or Nikon 200-500 and re-sell for almost no loss on return (assuming it doesn’t get damaged or dusty) I have the 200-500 and it is a lump, not sure I’d want to carry it everywhere.

Maybe something like a 70-200 2.8 with a 1.4/1.7 tele converter, 1.4 would still give you f4 and on you crop, the 70-200 would give you more like 105-300 and with tele 140-420 odd (not done exact maths)

It will still be short for wildlife ect but would be a bucket load lighter to carry.
