Redbull portugal

[SilverOnemi]

Red Bull airshow is coming up here on portugal, i'm going to porto ( if any potns menbers there i'll gladelly go shoot with them.

and i'm wondering if my 70 200 zoom range is enought, i could probably buy a kenko 1.4 tc but that would kinda ruin my €€ for tamron 17 50.

here's my lastest try with sigma 18 200

they say you want at least 400mm for the redbull air race

[SilverOnemi]

that's kinda crap .... now i must vs the TC against the tammy -.-''

[Zilly]

i have never tried it
but the 70-200 doesn't react well to tele converters

[SilverOnemi]

what ? canon 70 200 F4 L IS doesn't react well to TC's ?

[Zilly]

nither of them do from what i remember their are multiple post on here about them have a search

[SilverOnemi]

what ?! according to photozone this is THE BEST lens interms of sharpness and iq from cannon ?, i've seen threats arround here that says a 1.4 TC on it has no impact on IQ ?

and you're also aware that there isn't a single BAD COPY of this lens on potn ?
are you SHURE you are refering to my F4 L IS ? and not the f4 or the 2.8 ?

edit: besides that, i can't possibly see a bad spec on this lens... it's total perfection.

[Zilly]

im not talking about the lens the lens its self is great but from what i remember when using telecoverters it results in IQ degradation


and you're also aware that there isn't a single BAD COPY of this lens on potn ?

bit of a sweeping statment


are you SHURE you are refering to my F4 L IS ? and not the f4 or the 2.8 ?

Easy there guy.....you started the sweeping statements by saying that the 70-200mm lenses don't do well with teles. That's not true. They perform just like any other lens with a teleconverter...the Canon teleconverters are supposed to have fairly good optics. I have a 2x teleconverter that is alright with my 70-200: they're good for what they are. No, they aren't as good as a lens at that FL....but for cheap and portable use, you can get decent photos from them. The 2.0x has more degredation then the 1.4: so the 1.4x is more popular for telephoto work.

I use both TC's on this lens. and I feel 1.4x is almost no degrade in the IQ. its noticeable slightly with the 2x. I even stacked 1.4x + 2x and yet able to get printable result.

here is a test shot with the 2x. No PP, shot in JPEG L straight out of camera
first resize and second 100% crop.

Hey i don't wanna start a discussion about this, but there is really no bad copies of this lens so far, since it's f4 construction is easy, yeah true it's not 2.8, however i don't see it has a bad side... offcourse i could start complaining about lens not being F1.0 ? ,besides it would never be as sharp has it is if it was 2.8, even the if you stop the 2.8 version of this lens to f4 , it won't be has sharp has it is.

i don't get this "*insert sarcastic remark*"

i just noticed i posted this on the wrong section, and honestly i'm just trying to make shure this would be a good or not,tomorow i'm going to the river and i'll know if i need it or not, but since this is a year event i'll probably buy kenko 1.4.

[farrukh]

Another one. 2x tc. 400mm, no PP, JPEG L.
first resized and second 100 % crop

If you add some USM to it, it will become razor :D

i have never tried it
but the 70-200 doesn't react well to tele convertersThe 70-200s are generally considered to do better than any other zooms out there when used with good TCs.

[Davidoff]

Olá, bem gostava de ir ver a corrida..... Anyway, I think what everyone is saying is that the image quality with the converter won't be as good, but doesn't mean it'll be bad. I too think 200 mm isn't enough for the air race.

[Michael]

I used my 70-200 2.8 on the 30D with the 1.4X TC last year at the air race final in Perth. It worked fine, although I was intimidated by the guy with the 400 2.8 next to me :).

[JWright]

they say you want at least 400mm for the redbull air race

Who says?

I can't locate the course map for the Portugal races, but looking at the map for Budapest (and San Diego) I think you're going to be close enough to the action to get perfectly acceptable images with the 70-200. I fully expect that my 100-400 at the long end is going to be too long for the races in San Diego.

[SilverOnemi]

david add me to msn.

eye i also think 200 is short, but i'll have to live with it, and cropping won't be a problem.

This is a shot that was taken using the 100-400 here in Ireland a while back.

Depending on where you will be to the aircraft, the 70-200 might be ok but with the 100-400 you will have better chances of getting much tighter shots too.
