I use a ZV e-10 have any recommendations for a lens
Thatās a primarily video-focused camera, Iām not really qualified to answer for good video lenses as the requirements are pretty different.
I got both the lens and camera together at around $180 both used.
So In terms of upgrades what camera and lens should I consider next when upgrading?
Something which could handle high-level/altitude/contrail planespotting which Iām also interested in. Iāve done a little research and I know Iāll need a bigger telephoto lens i.e a 150-600mm or a general telephoto lens + a teleconverter or a just a telescope.
Iām not too well versed in contrail spotting. 150-600 on a crop sensor camera will probably do good enough but you wonāt get anything super crisp. You will be able to easily identify the aircraft and airline and if thereās text on the underside of the wing itāll be readable but youāll probably still have to crop a bit. It could be a good option if you also want to military spot a lot, but a 150-600 on a crop sensor can really be limiting for commercial spotting at an airport. I donāt know anything about telescopes so Iām going to refrain from giving advice there.
So in general my next upgrade I should consider a Full frame camera right?..So any options in mind on the cameras I can consider to get the job done, possibly below a $1000 budget.
Depends. I personally believe if you donāt care about night work there is no reason to get a full frame, and especially not for $1000 budget. Full frame setups tend to be at least 1500 unless youāre buying the absolute bare bones.
