Camera Labs

I have chosen the Canon T4i with the Canon EF 24-105mm f/3.5 lens and the Sigma 10-20mm f/3.5 wide lens.

Why that camera cus its what I will afford in a few months, why those two lenses, well thank to dubaiphil and other that showed me how important lenses are I did some great research.

I thought of what I will shoot and in what environments, I plan to shoot only a few humans indoors with most of my subject humans, animals and other scenes outdoors without going into too much detail the ef 24-105mm is the only zoom lens with the focal range I want with a constant aperture.
And as its a crop frame camera I will use the equivalant focal length is 38.4-168mm, I determined 38.4 equivalant is wide enough for me for a general zoom lens.
Because I will be using a crop frame vignetting and distortions will be a very small problem, though i believe flare still will be if i get the sun in my view.

Why the sigma 10-20mm 3.5 lens, because its a great wide angle lens to compliment my general zoom as based on comparision tools its has well controled flare vignetting and distortions, as you know this lens is for crop frame cameras.

I have done a lot of research and i understand almost fully what I want and why I want it, only thing now is to clear my current expenses so i can save money for what I want!

Are you...? ZEMBANU?

LOL. Yes I am. And Old Carlos yes I have asperger's syndrome.

As I said I did a lot of research, I have join a great lively organised forum called www.photography-on-the.net

www.the-digital-picture.com has allowed me to see using comparitive tools the flare vignetting and distortions of different lenses for full and crop frame.

I have first and yes dubaiphil to thank for showing me how important lenses are and the rest o yu for your advice.

I chose my camera and my 2 lenses as I said in my first post.

Now I just have to buy them.

No probs LE

Just PLEASE stay (as you have done) in a calm & friendly manner. Everyone on here wants to help anyone willing to listen. Enjoy.

Shall we start afresh!

Personally I'd go with the variable aperture Sigma 10-20mm.

Why?

1. With an ultra wide angle you'd generally be using a smaller aperture anyway, so variable aperture/slightly slower isn't so much of an issue.
2. It's cheaper
3. It performs better
4. Filter Size is 77mm vs. 82mm for the f3.5 (cheaper filters and maybe the same size as your Canon lens)

dubaiphil you say the sigma 10-20 f/4-5.6 aperture performs better, tell me how that is!

I chose the 10-20mm f/3.5 as it has sharper images than the f/4-5.6.

Unless they have changed the lens design, which I doubt, it won't be as sharp in the corners or as sharp generally.

I know - I've tried a few when I bought my 10-20 f4.5-5.6 a few years ago.

Save yourself a few $$$

Thanks dubaiphil, I will seriously reconsider!

And dubaiphil and anyone else who has experience can answer, what is the highest aperture I need to take landscape photos in sunlight and on a DARK rainy day?

With a tripod, whatever aperture you want.

Hand held, anything which gives you a shutter speed of faster that 1/30th second on a 10-20 should yield an acceptably sharp image. Be that by increasing ISO to an acceptable maximum or stopping down without it affecting your desired depth of field.

so 1/30 of a second is the slowest shutter speed I need to get an acceptable sharp image, thanks dubaiphil.

Welcome back, and nice to see you decided on gear!
