Tamron 18-400

For those considering the Tamron 18-400, this is a sample of an image taken at 400mm (AP, 1/640, f18, ISO 1250 auto). The image is the full non-cropped shot from my Canon T7i, with a Polarizing filter. I was pleased with the quality.

F18 with a polarizer ?? that's a little under exposed - ALL lenses will look good at f18 !

f 18? ISO 1250? POLARIZER (= 1.5 to 2 stops)
Were you doing a test for camera noise? You are probably aware that lenses usually start to suffer from diffusion induced softness about f 9 You could probably have wrung more sharpness out of your lens quality example by using a different set of exposure triangle compromises.

Still new to the non-auto world, still learning. It was set for aperature priority, so the cam picked the other 2. Polarized filter is always on my lenses. This was shot early in the pic session, and did not remember to rotate it for effect until later. Don't know if it had a positive or negative effect on this pic. The reason for my post is that others on UHH have questioned on the quality of this lens.

Have the Nikon version of the Tamron 18-400mm and am happy with it given a few caveats. My lens needed tuning, but once tuned it is sharp over the whole zoom range. The focus ring turns when AF is active, you have to turn off AF on the lens to use manual focus and there is some chromatic aberration and distortion, which are easily corrected in PP. On the other hand, VR works great and the lens is light and compact for its versatility. I especially like it for family vacations when I don't want to take a lot of equipment with me. Enjoy!

Backstop,
I inherited my Dad's camera gear Dad had polarizing filters on each of his 3 lenses. For your future enjoyment please remove your polarizer. And if you have a clear ivan protector take that off as well.
They well not protect your lens, and they are costing you light and IQ.
You probably read somewhere, I did - my dad did- many did, that you need the filters. You don't and its hampering your gear and your enjoyment.
Please add, if you have not already, a lens hood. That will protect your lens as much as it needs, more then a screw in filter.
Using a circular polarizing filter is occasionally helpful but only if you know how to use it.
If you don't believe me please stand by. Other comments will follow.
And you can always just try shooting sans cpf.
're your f stop
Why would you shoot at f18?
Did you intend to say f8?

Zooms do come with advantages and disadvantages but the caveats of sharpness are often traded off at certain focal lengths. Equally I'm not very fond of variable apertures but to conserve space and size when I travel, I use a 70-300 4/5.6. I don't consider this a great shot but it illustrates the sharpness levels that can be easily achieved after a little post work. Shot at minimum Fstop at F5.6 at 300mm IS0 100 at 1/100 sec handheld. I realize IQ is extremely subjective but for myself, this is what I prefer at a minimum. Thank you for sharing btw. It's good to see people trying to give others a representation of what can be achieved with any given lens.

The Tamron 18-400mm f3.5-6.3 Di II VC HLD was the first lens I bought (I don't count the kit lenses that came with the camera) once I decided to get a bit more serious with my digital photography. I wish it had a bit more range in aperture but if I have my Canon EF 50mm f1.8 I can handle the vast majority of situations I find myself in. Not having to carry bags of glass around with me at a conference, convention or event is highly rated in my book (I'll leave the Tamron on the T4i and have to Canon on the T6 in my bag for fast switch or rapidly deploying both cameras for simultaneous shots from different angles).
I've been able to get some pretty interesting shots of Saturn and Jupiter with it among other things.

Short and sweet, I have no personal experience with the lens. However, two years ago, I attended a workshop in Costa Rica where two users had the lens. One on a Canon 7d2 and the other on a Nikon, both were very pleased with their results.

I have several recent posts of my photography in Kruger National Park, South Africa. The vast majority were shot using the Tamron 18-400 on my Canon 90D. It's a good lens - proof is in the pudding, as they say.

"Still new to the non-auto world, still learning."
Nothing wrong with learning, that was the way we all started. At times we make comments based on what we see and read that are not very pleasant to the person posting but there is a lesson in learning in the majority of them. Now next time that you use the polarizer you will know how to make better images thanks to those comments.
I see no reasons to use a polarizer at all times. With a body of blue water the polarizer will darken the water which is desirable and with a blue sky with interesting clouds it is invaluable. It is also a great filter to eliminate non metallic reflections, like those on leaves after a rain. A polarizer will take away 2 stops of light from your exposure at full polarization. It works better with center weighted and spot metering because using evaluative metering the darkness of the filter confuses the meter...unless you watch the histogram at all times.
If it is not necessary do not use the polarizer and when you do remember to clean it and clean the lens for better images.

I love my 18-400 and have had great results with it. I have never had it fine tuned, I have wondering if I would notice difference?
