Best Macro/Telephoto Lens?

I am looking for macro lenses when i found the Sigma AF 70-300mm f4-5.6 DG Macro Canon Fit Lens

First, no zoom lens is a real macro lens. In my opinion lens manufacturers who include “macro” in the description of a zoom lens are guilty of misleading people. A zoom lens would be better – and more honestly – described as “close focusing”.

A true macro lens will always be a prime lens – fixed focal length, no zoom – such as 50mm, 60mm, 90mm, 100mm, 105mm etc. With a true macro lens you will get a 1:1 (life-sized) reproduction ratio. Photograph an ant that is 10mm long and the ant will be 10mm long on your sensor.

A close-focusing zoom lens will seldom (if ever) exceed a 1:4 (1/4 life-sized) reproduction ratio. Your 10mm long ant would be a mere 2.5mm long on your sensor.

Like any prime lens a true macro lens is optimized to give better center to edge sharpness and less center to edge light fall-off at all apertures although all lenses are designed to give their maximum performance at between f5.6 to f11.

To achieve a nice out of focus background (what you called blurry) requires having knowledge of what Depth of Field (DOF) is and how to control it. There are only 3 factors that affect your DOF:

1) The focal length of the lens.
2) The f-stop used.
3) The subject distance.

This site will help you learn about DOF: http://www.dofmaster.com/dofjs.html Once you have a better understanding of DOF you can use the DOF Calculator to compute your DOF for any combination of the 3 factors imaginable.

If you know how, you can use the 18mm end of your 18-55mm zoom and have a very out of focus background. Here’s proof, using the DOF Calculator.

18mm @ f3.5 and focused on a subject 1′-0” away your DOF will be from 0′-11-1/2” to 1′-0-3/4″. Anything from 0′-0-1/2” in front of your subject to anything 0′-0-3/4” behind your subject will be in focus. That is a very shallow DOF.

You say the 18mm end of your zoom is kinda soft at f3.5? We’ll stop down to f5.6 then.

18mm @ f5.6 and focused on a subject 1′-0” away your DOF will be from 0′-11” to 1′-1-1/2″. Anything from 0′-1” in front of your subject to anything 0′-1-1/2” behind your subject will be in focus. This is still a very shallow DOF.

You say that you think the 18mm end of your zoom performs best at f16?

18mm @ f16 and focused on a subject 1′-0” away your DOF will be from 0′-9” to 1′-5”. Anything from 0′-3” in front of your subject to anything 0′-5” behind your subject will be in focus. This is still considred a shallow DOF.

You say you’d like to get as much in focus as possible for your landscapes? Easy enough – if you know how.

18mm @ f16 and focused on a subject at 5′-0” your DOF will be from 2′-1” to infinity. Anything from 2′-11” in front of your subject to as far as you can see behind your subject – infinity – will be in focus. This is a truly deep DOF.

We have now proven that by using the right combination of f-stop and subject distance we can achieve a very shallow DOF with an 18mm focal length and with the same focal length and a subject farther away we can achieve a very deep DOF.

Now you can try the same experiment using the 55mm end of your 18-55mm zoom except you’ll have to start at f5.6. Use f11 and f32 as your other f-stops. HINT: You’ll have even less DOF at all apertures at 55mm.

In my opinion the 18-270mm lens will be a nice “walking around” lens since it goes from wide (18mm) to high-medium telephoto (270mm). You won’t need to change lenses as you would with the 18-55mm and 70-300mm.
