Hello All this is My Very first post ! i'm a young man interested in photography, and have been taking photos for around 4 years, mainly wildlife as i live in south africa ! I'm just seeking some advice on a new lens, and am looking at the canon ef 100-400 is usm ! comments on this lense please ! or sample images ! or any other recommendations ! using a 20d ! thanks alot...
Before I start...lemme comment.. EXCELLENT pictures !!! something I really dream I should get.
But I was wondering that you guys are talking about 80mm, 200mm and stuff..How do you manage to get so close to the subject.
I have a 300mm and even with that I am never able to get so close to the birdy and get a full frame picture of it.
Hi All i just orderered a canon ef 100-400 is usm... and was just wondering which uv filters to get !! or just a protector !! please share youtr views and experience !!
I'm assuming you are talking about the UV filter as protection for your lens. In that case you don't need one. Why pay over $1K for a lens and then put $20 of glass in front of it?
Put on your lens hood and be careful. That's all the protection you will need.
Thanks alot for the advice ! so I am assuming that you don't use filters ??
Hi again all ! was just looking at lenses for landscapes, and was wondering wat u shoot with, so far i've narrowed it down to the sigma 18-50 f/2.8, the canon ef 10-22 USM f/3-4.5 and the canon ef 17-40 f/4L USM
Any other suggestions ? please share your views ! thanks alot, much appreciated
This is a question better suited for the Field and Street forum where landscape shooters hang out.
I want to say "thank you" to the many posters over the course of a year. I was going to post a thread titled "Going on Safari Africa ... how much reach and speed will I need?", but I don't think I need to now. Feel free to chime in and offer your thoughts however! But I think a 80-200 f/2.8 + 1.4TC and/or 1.7TC, or 300/f.4 + 1.4TC or 1.7TC is the answer.
I am a Pentax shooter, for mainly features and built-in-body IS; oh and dust removal (I was sure Nikon would announce a new D200 model upgrade with dust reduction the week after I bought one; as that was the main contender). I'm in the process of trying to decide which lens to buy -- options are either Sigma Bigma or 300 f/4 new if I get word from my contact there they'll have a deliver this week, or used FA* Pentax.
So with all that said, I surmise from all this that when out on the savanna... - 200mm f/2.8 zoom + 1.7TC is minimum- 300mm f/4 | f/4.5 prime + 1.4TC is better- 200mm f/2.8 zoom + 1.4 & 1.7 stacked TC even better if I can live with the f/6.7 speed?
...or I get a Bigma if they become available in time for my trip ( less then 2 weeks)... :confused
EDIT: It's the next morning from this post. I got word this morning from the -extremely- helpful folks @ Sigma America that they had a 300mm f/2.8 in Pentax mount. I decided to buy it!!! That, plus the 1.4x TC, plus the 2x TC... I'm pretty sure I'm set!
Hi there, these are great images and you know your gear well too, thanks for the detailed reviews, I'm interested in which of these lenses can deliver the best results
The 300 2.8 should just about be the perfect lens for you.
I'd gladly sell/swap the 300mm f/2.8 Sigma prime <lol>.
I'm sorry to say I'm a complete 'newb' to -real- cameras (non-point'n'shoot) so can't draw any relations to Canon's.
The lens is very capable of excellent sharpness at f/2.8 as is evidenced by me when I stood outside my day-room the last day of the, trip and took pictures of the multitudes of humming bird-like birds (they just didn't hover when feeding on the flowers) at a distance of a few feet while it was heavily overcast and misting even. I wish I had my HyperDrive here @ work as I'd convert some RAWs to JPG and post'm. If anything, it showed the limitations of the AF system of the K10D in its difficulty in achieving excellent sharpness on -every- shot; some are outstanding, some not.
If I have any serious criticism to say, it is that it doesn't have a focus limiter. Focus is fast -- and I have the non-HSM, Canon/Nikon versions are HSM which is supposed to be much better and quieter. However if focus isn't achieved within a few iterations, it will hunt to the far extent of the range and back. Even then, time to do a full cycle out and back for the non-HSM version is just a fraction of a second; though an appreciable fraction of a second (i.e. 100's of milliseconds).
My technique in holding the camera+ 5+ lb. lens on a flying bird using spot focus leaves -much- to be desired, so I have to say -I- was the governor on any ability to AF birds in flight (I realize now I should have switched to matrix focus). I'd say again though, not having the focus limiter could produce periods of frustration, where if you are on continuous focus (needed for birds in flight?) and you loose the bird for a moment, the lens is likely to run from where it is to infinity or min focus and back. That is only supposition however; keep in mind I've only been at this 2 months!
edit: Ah, i forgot! Some past -- non-wildlife -- shot I have taken, some of which are wide open.
a) a 'example' of Bokeh and sharpnedd over f/2.8, f/8 and f/13:http://public.fotki.com/m8o/memorable_images/the_natural_world/flowers/sigma-300mm-f28-dof/

I was wondering how you liked the 300mm other than the issues with being a fixed focal length and comping on the fly. Was this tack sharp wide open? How about auto focus accuracy and speed. Did it seem fast enough for fast action wildlife shooting? Have you ever used Canon's 300mm f/2.8 "L" ?? I was wondering how this Sigma compared to the Canon. It's about $1600 less than the Canon variety. The Canon does have IS, but for the extra money..I can live with the lack of stabilization and the ability to buy another nice lens.
Anyone else used this Sigma 300mm and the Canon. Would love to hear your opinions on these two lenses. I can't stand a slow focusing lens. The tokina 300mm I had just didn't cut it for flight shots. Focused way too slow. Sold it and am looking for a cheap alternative to the Canon 300mm f/2.8.
The cheap alternative to the Canon 300 f2.8 IS L is the Canon 300f4 isn't it?
