Is a Tamron (for a Canon T3i) AF28-300mm F/3.5-6.3 XR Di VC lense a decent choice? Is there a better brand? Should I stay with the Canon brand?

No, I don't know why I want it. I love to experiment on:

I have never used it but I think generally speaking any zoom with that kind of range is not going to be a great lens. It will likely be good at one end and rather soft at the other. For what it is though it seems to be a nice lens at that price.

You might want to check in the lens discussion section:)!

https://photography-on-the.net/forum/forumdis​play.php?f=33

Also try a search for the lens name and see if you can see some samples and reviews!

The T3i is a cropped sensor so keep in mind that the effective focal length is 46-480mm for the Canon mount. So if you are after some wide angle effects at the 28 mm setting, it won't be delivered. What you will get is 46 mm. The 28 mm will only be realized on a full frame sensor. The upside is the lens is useable on both the cropped sensor and full frame sensors so if you decide to move to full frame in the future, the lens is still useable.

Thanks John! So, if I look at the term used, "Cropped Sensor", and apply a bit of logic, the camera precrops the view it sees, right or am way out in left field.

Not quite. A full frame sensor is the physical size of a 35mm piece of film. The sensor on our camera's is less than that so it can only "see" part of the entire frame the lens is capturing (with the exception of EF-S lenses, which are designed to only capture an image in the smaller sensor's surface area).

The T3i has a APS-C sized sensor. It's not a cropped sensor as people suggest, it does however have the 1.6 crop factor because it is designed to be smaller than a 35mm sensor like what is found in the 5D or 1Ds.

You've got a awesome camera out of the T3i, so I wouldn't worry about sensor sizes.

In some ways I like it. You get that extra "reach", and man the on-subject pixel density on these 18mp sensors is insane. Gives you a lot of cropping freedom of the final image to pull it in more or just frame it up better and still be able to print at decent sizes.

As someone who likes to shoot a bit on the wider end of things, I'd push for the Tamron 18-270mm VC PZD. You're going to get nearly the same reach, but are going to have a good wide angle as well.

As for the quality, as was mentioned above, getting two or three lenses to cover that range will yield better results in terms of total IQ, but will cost you both in terms of money and space (the Tamron is not much larger - if at all - than the kit 18-55IS). The Tamron does consistently rate better in overall performance than the Canon 18-200mm, plus it gets you closer by nearly half again.

"You've got a awesome camera out of the T3i, so I wouldn't worry about sensor sizes." True, but you do have to worry about the sensor size, otherwise you buy what you think is capable of 28 mm and you won't do any better than 45 mm. The 18 mm that someone suggests will yield approximately 29 mm which by your original post is where you want to be.

You might also consider the Sigma 18-125mm F3.8-5.6 DC OS HSM (see http://www.sigmaphoto.​com …mm-f38-56-dc-os-hsm-sigma (external link)). That will give you effectively 29 mm at the low end and 200 at the "long" end
