This is a common problem.

It's something that a devout pixel peeping lens testing junkie will say.
Although it's a technically correct comment that they have made, it's not something to be taken as gospel!

You make your choices based on your requirements .. if you need professional level image quality, then you probably have the cash flow to achieve lens nirvana and you'll end up with a collection so large, it forces upon you an even greater problem that of the logistics of choosing the right lens for the right job.

This becomes a compounded issue that when choosing to carry the correct lens is not such an obvious decision, you subsequently have the logistics issue of how to carry all this gear so that you ensure you do have the right lens for the job.
These people are more about pixel peeping rather than just getting the gear and going out and having fun!

The rest of us who just want something that does a job, we just purchase and use what's more convenient for us.

I think that if you decide that a 70-200/2.8 Sigma + TC is what you think you want, then this is obviously the right choice for YOU ... but obviously not something that the boo-hoo person will ever use.
