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


tbh, it'll depend just how steady your hands are. Being older I struggle below 1/80th sec, :roll: but you'll just have to try it out.

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


It took a lot of researching and thinking as to what pics i want to take,

I will say it here, the rest you can read on my link as I am ZIM SOGEN on that forum.

I want to take portraits, full figure humans pics and local wild life and stray domestic animals that work with and hunt wildlife. In both bright and low light.

the wide end of the 24-105 on a crop is wide enuf for me for walk around, and I plan to buy a wide lens, thanks to dubaiphil I am now rethinking which wide lens I want of which I added the canon efs 10-22mm to my choices!

I've never heard that. What does wide angle have to do with small aperture?

I really love my Rebel T4i. After reading the manual completely, I loved it even more. I was considering the T3i with a lesser lens, but I'm so glad I upgraded (touch screen feature is awesome). I'm also glad I upgraded to the STM lens for video. You can see the lenses I bought in my sig.

You won't be so worried about shallower depth of field and would want to maximise it - so you'd be more likely to be shooting in the f5.6-f11 range (f16+ on my Sigma 10-20 resulted in some quite serious diffraction)

The starter of this thread is living in the Caribbean - probably unlikely to be shooting darker museum interiors and the like where a faster aperture can overcome not being able to use a flash.

Oh, wait. This is a terminology issue. A 'small aperture' is f22. You (dubaiphil) meant to say 'small f-stop', like f3.5. Well, that makes more sense.

Yes, I understand that a wide-angle lens extends depth-of-field even at small f-stops, like f3.5.

f/8 is pretty small compared to f/2.8, Phil is 100% right about that. Shooting landscapes with f/3.5 makes no sense, so youll be shooting with f/5.6-11, which means that it doesnt matter how fast your lens is, youll be stopping it down anyway.

I have not replied a while, choosing a camera is easy, the lens is hard.

If I were to buy one lens I want a general purpose zoom, the 2 lenses I have chosen for this are the EF 24-105mm f/4 and the EF-S 15-85mm f/3.5-5.6.

Whats most important to me is aperture and focal range, I want a lens with a high aperture at the long end and a wide focal length.

The efs 15-85mm has both a wide end but at the long end the aperture is too low, the ef 24-105 has a constant aperture with a very long end but I dont know if 24mm which is the full frame equivalent of 38.4mm on a canon crop frame is wide enough.

Whats more important to me is my ability to shoot close subjects in low light which is natural light, such as evenings and cloudy days without using flash, to me flash is not natural light!

The long end of the efs 15-85 is long enough for me, its just the aperture at 35mm (56mm) is as low as 4.5.

Pls tell me your advice on this thank you!

I already understand clearly that a small aperture is need for wide end and landscapes, what I need a large aperture at 3.5 for is for close subjects in low light,

again I want to choose between the efs 15-85mm f3.5-5.6 and ef 24-105 f4.

the problem with the efs is that the aperture at the wide is a higher than i need and the long end the aperture is too low, agen I want to shoot close subjects in low light like evenings, early mornings and cloudy days, I dont want flash as its unnatural light.

With the ef 24-104 I am not sure is 24mm is wide enough for a crop frame.

If any of you could post a landscape picture (wide picture) of a far off landscape at 40mm on full frame or 24mm on crop frame to show me what those focal lengths look like it would help me decide, thank you!

hey mark how well does f5.6 do in bright sunlight compared to f4? do yu have pics to show examples?

And after taking a much closer look at the efs 17-55mm I realised that lens is an efs version of the ef 24-70mm f2.8 IL or IIL.

I am considering this lens!
