Welcome to POTN Stu
Want to keep your shutter speed up, then start shooting in M mode, get away from AV or TV.. Practice. Practice, Practice
Example... set the speed you want, then the aperture for more or less DOF, watch your metering and see where your at, and adjust Iso if needed....Adjust all parameters accordingly....Don't let the camera do these things, your in the drivers seat in M
The 7D II would be my pick for what you want, it will be great with your 300
Good luck & Happy shooting
Thanks Bianchi!! Cool forum this i've been lurking a while on several,but these are my first tentative posts. This is a much covered subject with info here but what a lovely response to try and help a newer guy get his old brain around all this the word thankyou will appear much I guess,those thanks are genuine cheers all.
Bianchi I probably understand manual better than the others,that's what I shoot in all the time,unless i'm taking quick reference snaps of our frogs that is (another story best not go there for the mo:lol So it is that awareness that I need to keep shutter speeds up with these tiny things that shoot about too bloody fast that is driving my questions about high iso. So often in blighty the light seems, well, not strong enough so the iso is getting bumped ever upwards and I'm seeing the effects of this. I'm almost being steered with the questions to help me make the right choice by the areas I struggle in with my little 550D. But that is tricky because I know my skill/knowledge levels aren't great so I might be making incorrect asumptions.
Yup I try to get my eye in and have the lump of lens and camera in hand most days. i'm practising with swallows at the moment nice and easy,well not really. almost no chance of a keeper with my ability and the focus prowess of the 550,I have to guess roughly where a swallow will appear set rough focus to there and try and lock on to get a chance of tracking. But really the pictures aren't important what i'm trying to get to is a place where I've aquired the muscle memory to mount the camera to my eye accurately and very fast. Swallows being so fast and tricky to track also help me think on where my ruddy feet are pointing getting that right will help with the tracking I hope!! As always a work in progress,mind I'm getting some great pics of a blank sky at the moment,lol,a bird in frame is a cause for celebration . Ahh the quest to be better at something and the insanity that follows.
I sort of suspected some folks would say 7Dii some 1Div ,I need these cameras in my grubby mitts really,but this thread is incredibly useful having others experiences and points of view is a huge asset
cheers for the welcome kiddo
