The Tamron 18-400 And Three Types Of People......
May 19, 2018 14:47:08 #
Type #1: Those considering buying this lens
Type#2: Those who own this lens and may wish for better sharpness
Type#3: Those who would not be caught dead with this lens on their camera.
This post is for the first two types.
Here are photos I took today at a local park. This demonstrates the versatility of the lens. There is no sharper 18-400 lens made. No matter your opinion of this lens, that is a fact.
I am working on improving the sharpness of my photos using this lens, in 2 ways:
1. Paying more attention to the f stops I use. I found a web site called Photography Blog. They give this lens a Recommended Rating. In their review of the lens, they show the sharpness of the lens at different focal lengths, and the sharpest range of f stops. At 400mm, the lens is sharpest at f/11-f/22. All the attached photos were shot at f/11.
2. Moving my focus points on the camera instead of using focus and recompose. This is more for macro type shots and objects that are somewhat closer to the camera.
I hope the above may prove helpful.

Did this Blog also tell you that shooting at f11 will run your ISO up - which also destroys sharpness - especially on a crop frame sensor ??

You state that there is no sharper 18-400 lens made, and that is a fact. What proven facts are you basing that statement on? Fact and opinion are two different things. I happen to fall into category 3.

They used a Canon 80 D for the blog. I used a Nikon D5500.
They showed the results at 18mm, 50mm, 100mm, 200mm, and 400 mm.
At 18mm they found the sharpest setting to be at f/4 to f/11.

Tamron is the only manufacturer that makes a DSLR lens that goes from 18-400mm.

The superzooms are quite convenient. But image quality is far from professional in quality. Fine for casual, memory snaps.

Some superzooms are better than others....but generally, the greater the focal range the poorer the image quality. 18-400 is a HUGE range over which to expect an optical system to perform optimally. I've recently moved to FF, and have settled into Nikon "gold band" lenses....with much greater quality images. Not cheap....but amazing.
There are several sources of lens data....many showing sharpness @ aperture settings. There are trade-offs involved. Small apertures can cause dispersion effects...which can cause degradation of apparent sharpness. Also, small apertures will require more light, slower shutter speeds, and/or higher ISO. Generally, I stay away from any lens that needs to be stopped down to f/11 or f/22 to reach maximum sharpness.

I understand the discussion, Dean, and more expensive lenses are sharper as tests will prove, but to a plugger like me, those are beautiful images!

Dean,
I'm not a pixel peeper, so those images look fine to me. Keep on shooting; keep on posting.
Thanks,
Don

My self I think this is an excellent set and I also have this lens and love it. It is my main walk around. In my opinion people that have a problem with this lens just don't know to use it properly and use proper and simple PP....Rich

I think you mean diffraction, not dispersion. Completely different phenomena.

Quite a generalization. You paint with a very large brush.

Compare it to a pro caliber lens. It very well may be fine for the needs of many shooters.
