I had a sigma 300 mm and I thought it was ok...I think it was a 100 300 f4
We were taking pics of hares in the snow
My mate had a canon 300mm f 2.8
We took the same pics of the same hares
His were good mine were all soft
I sold the lens that week and bought the Nikon 300 f4..... Loved it
Had my first year as a beekeeper.....didn't have a clue what I was doing but with books ,you tube asking every bee keeper I met stupid questions.i eventually got 20 jars of honey
I have tried and sold loads of lenses
from now on I will stick to Nikon all the sigmas I had were not sharp
50-500 no good in this country ..I take action shots so need loads of light
what cartridges do you use through it mate?
I don't buy subsonic cartridges ....I just shoot whatever I have or the cheapest ...some are quieter than other ...eley are quiet... to be honest theres not much difference between them
Put lead on ,make a loop near its head and slip the lop around its nose ...it's make a halter ..when it pulls it will pull its head around
After a while it will get used to not pulling
