There are definitely times I want more light. Especially as I generally hand hold. Both the shots of mine on this page would have been missed if I was on a tripod
I was looking at getting the Mt 24ex
Something other than an insect for a change
I need a better lens but this is the best I could do with my current rig..
Are those quite heavy crops or is that the lens as it is? Apertures of F22 and F32 definitely won't help keep your shots sharp and neither will long exposures. I take it these were on a tripod or have you got freakishly steady hands?
Anyway, I'd try to keep the aperture where your lens is sharpest and if you're not sure what that is for your lens in particular, I can tell you that it's rarely at such small apertures so you'll want to keep it at F16 or wider. That will give you sharper shots that don't require such long exposures.
Other than that, you can work on your lighting if you want to improve without getting new kit. It's a hard one to practise unless you've got flashes etc but if you can get the right kind of light then this certainly makes a shot better. These shots like they were take in the shade or on a cloudy day and it's very hard, if not impossible to change this in processing so it's always worth bearing in mind.
i actually dont know where the optimal aperture is on my 100mm L
either on paper or on my copy
something i should look at
i usually find i use Tv to specify a speed.
in the grand scheme of things i prefer a really sharp shot, even it it is only a cm or two DoF
if i lack light, its the aperture which gets opened
problem is, if its windy its impossible due to narrow DoF
edit,
just looked, looks like i generally use the optimal for this lens and my body around 4 to 11 usually.
its more for needing the light to achieve the speed though
I guess it's good to know what your lens can do. Even if you don't always stick to it, it does help you in figuring out what might work and what might not. Tiny aperture will never give you the sharpest picture in the world but sometimes they're a necessity if there's some insanely bright light or you desperately need bigger DOF. Luckily the 100mm F2.8L is damn sharp so you can afford to lose a little
TV mode can be handy if you're wanting a particular exposure but you're then at the mercy of the cameras metering. I'm usually in AV/TV but sometimes they're far from ideal when the conditions start to change.
Thanks
It just all looks a bit grey and uniform in B&W.
