I use a 150mm - 600mm on my Nikon D810 full frame and had a X2 converter, to be honest as soon as I used it at anything over 400mm I wished I had a 1.4 converter. Image quality was not good enough for my liking.
Sold the X2 but not yet replaced it with a 1.4 but will one day probably later in the year now.

That sounds promising
The dof calculator app on my phone says the diagonal field of view will be 4.5 m with 1000mm at 105m. Will be a bit closer at 1200, might be OK for a shot of the family group but I'll still be hoping for them to fly in my direction. Even in a fairly steep dive they will quickly be at 75-80m
I'll be hoping for a chance with the speedbooster which will get me to just under 900mm but gaining a stop of light, and a fair bit sharper judging by other lenses I've used with it.

I'd probably start off with a ball head on a tripod, I've already got a cupboard full of heads and mounts I've bought for macro stuff I never use, I don't want to add another

It depends. There's heat haze, mist and pollution to think about. Early morning to avoid the heat and you may get mist, early afternoon gives you the opposite. How much you are willing to put up with is another thing. We all have a line that we don't want to cross (like with ISO). I've got away with a 1.4x converter on a 150-600mm whilst using a crop body and have been reasonably happy with the result. On a bright, clear day I wouldn't hesitate to shoot at the equivalent of 800mm if that helps.

If your subject is 100m away, 1000mm is still going to require a lot of cropping for a bird. Magnification from a 1000mm will give you full height of a person at 100m (ish).

It is usually movement that ruins long lens photographs, use a monopod. I'd use a gimbal with that sort of focal length as well, if you can get hold of one.

A question for those with some experience with super tele lenses, how long can you go before atmospherics destroy image quality?
I'm thinking of getting a used 150-600 in Canon mount as I have an adaptor and a speedbooster, but since the pylon the peregrines use is around 100m to the lower tier from my garden, I'm not sure it's gonna be possible to get anything decent at 1000-1200mm equivalent.
Even without the lock down there isn't really a better vantage point, I can get higher but further away, or closer, but beneath them. Short of feeding the pigeons and setting up a hide to try and tempt them I can see a lot of fruitless hours trying to get a shot

It certainly looks like one to me mate. We had a bird keeper in the village where I grew up and me and my brother used to help her as kids. She had several peregrines.

I think so but I'm not great on identifying birds. The speed of thing once it took off I had no chance of finding it with the long lens.

The last couple of years they've been a regular sight when I have my morning coffee through May and June, never bothered to shoot them before as they stay out of range for a decent shot. Last year there were regularly 4 birds up the pylon, the year before 3, I think it must be a favourite spot of a breeding pair to teach the fledglings

Held the box off to one side to try and add interest, still not that happy with it but highlights are under control
P4240019

Excuse the poor quality (soft lens, 600mm equivalent handheld + very heavy crop), looking for an ID confirmation on this raptor

P4270464

I had the camera trained on it for over an hour hoping it would take off towards me, typically it decided to move the moment I'd lowered the camera to get some blood back in my arms

That rig looks more manageable

I'm gonna have a tweak of the softbox, because of the closer worker distance I have I'm getting nice diffused light but at quite a high angle. So I'm gonna either try and make a notch for the lens to sit in or extend the front to serve the same purpose, and maybe make a gap in the diffusion to let a bit through more directly, it seems a bit too flat now.

My daughter has permission from the boss to put some blue dye in her hair, so I'll be doing some portraits. Now, given my aversion to editing, can I make the blue really pop by using gels and tweaking the white balance? I'll probably use a warming gel on her face given her pale skin, and I don't think lifting the blue channel in light room will do her any favours there

Getting there with the diffusion. Found a great styrene film bag, that a monitor came wrapped in, for the end of the snoot and now have a bit of plastic milk carton elastic-ed over the end of the lens.

Gone back to the 5D as well, the weight of the 1D was just too much, half a kilo difference!
The AF is faster and more accurate. Sod the frame rate.

And typically the day I don't bring my camera I've got an exhausted bee taking sugar water from a fake flower

I think I saw the original on Instagram, either a photography page or some # that popped up, really simple to do but I thought it looked great and worked out how to do it straight away you could easily do it with a phone camera and a lamp if you can set the white balance manually, although I've used a camera and a flash with an orange gel

Might have a go a bit wider and throw some blue into the 'sky'

Was trying to do something similar but with star trails in the garden, using a granite worktop and buckets and bottles to make the horizon and hide the ugly views I've got to the north, but even in the small hours there's to many lights from the neighbours

Thinking about it, I might be able to use my tempest brolly as a light shield

Very nice indeed - magazine inspired?
I buy the occasional one for long journeys and they are full cool ideas like this.
