Spec me canon lenses for the following photography

Another couple of pics as to why you need 400....


Coming into land by King Damager, on Flickr

This was taken @400mm, on full frame (so effective length of 400mm), ISO 4000, 1/4000, f5.6 (I'm still experimenting with how slow I can go and still get away with freezing birds motion).

This was handheld (IS on), at about 4m.

This one, was at about 3m away, on a tripod (if I stand that close the birds get a bit skittish), shot remotely. Again, same settings as the other photo, apart from IS off and on a tripod. The only major difference was this was also MF, with the focal point being the feeder.

(You have no idea how annoyed I am that I cut the tail off the bird).

Both at full size by the way.

thats what i want.
nice pics of green finches and sparrows, i can imagine the annoyance of loosing the female tail!!

i am not amused! i was hoping to get away with less!!
you guys are cruel, you know that?

btw, these are my first ever shots using a macro and second time with a dslr at all
id appreciate some input
i think they were MF

i got my best with a nifty 50 in regards to focus, DOF etc but cant post, due to content

To be fair, that's actually at 400 on FF. So, a 300 on Crop would give you 420, which means you could have the same reach. But, as I say, the bird feeder here is all of 3m from the tripod set up. So, you could test out what you like with a wireless trigger and one of the better 70-300's that other non Canon Vendors do.

As a side point, how do you know that it's female?!

If I'm honest, I was visiting the gf, their parents are quite into birds, have the bird feeder and I saw an opportunity to get some shots, and some experience, but know absolutely nothing about birds... So, tagging etc... the shots is going to be somewhat of a challenge for me

im looking at a 400 arent i? meh!

Its a female because its colours are less vivid (most birds are like this as usually the female is sitting on a nest requiring camo)
saying that many birds are indistinguishable (from distance) but it is rare the female is brighter

im pretty good with birds and IDing them

Off topic, but our now departed beautiful jackdaw, without shadow of a doubt the best 'pet' i ever had

could you just explain why if the max aperture is f/8 why AF doesnt work?

I have only just learnt about aperture area in regards to focal length/stop value = diameter of aperture! and that f/x results in same light on the sensor regardless of focal length!

so a TC is no more useful than photoshop if the lens isnt resolving the image beyond the sensors resolution BEFORE the use of the TC?
im guessing this is one reason canon only enable TC with high end lenses? (as well as the stop loss)

At wider apertures the light rays exhibit a greater refractive angle, at narrower apertures the light enters the camera more parallel. The phase detect sensors don't work when the light is closer to parallel.


yeah, if the lens is not out resolving the sensor before the TC then adding a TC will not add any extra detail to the final image. And so yeah, that is why TCs are only officially supported on high end lenses, mostly primes.

thanks.

think my physics a level is actually useful for something now!

id also like to try getting some light trails over the motorway, i keep eyeing up bridges!
