Does having a pro lens turn your pictures from good to great ?? most professional photographers always advise you to buy the best lens you can. do you think that a $500 lens will produce the same results as a $2k lens with the same camera & the same settings ??
There's a guitar player and producer out there that you've probably heard but may have never heard of named Buddy Miller. Buddy plays these old plastic guitars from an Italian company called Wandre. They're often held together expertly by tape and glue thanks to a great guitar tech that works for him full time. Until people saw Buddy playing them they could be had for next to nothing, then they became a "thing". Buddy's the older guy with the funky hat in this video. Do you think that it would have been better with a vintage Les Paul or perhaps a PRS Artist?
Here's my point, before anyone misses it - there are tools for a job, and there are ways to get things done. A bad picture is a bad picture no matter what you use to shoot it -
no matter how much you polish a turd it's still a turd. Every piece of equipment has its own characteristics and these can be used to your advantage as well as your detriment. A photograph is not great because it's tack sharp,
a photograph is great because it says something as well as shows something. You can use cheap, cloudy glass to take a shot of a lifetime if your mind's eye can find it
before you squeeze the shutter. You can also produce utter rubbish with glass costing 5 figures. Both with the same camera body.
Pro glass, instead of what you have, will only make a difference in your photography when you notice
specifically why the glass you currently have isn't cutting it. Pro glass
can also open your eyes to those shortcomings after you've shot with it.
But when all other things are equal, pro glass will do nothing more than possibly impress pixel peepers and folks who want to find a reason to say
the lens is better, but not the photograph.
