Well not AGAINST kit lenses
I've always been stumped as to why a LOT of people here, and pretty much everywhere, always recommend newbies to buy all these expensive f/2.8 zooms and fast glass in their first few months. Here in my country and in our local photo communities I always see newbies asking "what should I buy next?" with no real clue as to why they need/want to buy. Then people surge in with answers "f/2.8 Nikkor/Canon L lenses" of all focal lengths.
I for one believe that sticking to the kit lens is one of the best ways to learn and ease into the world of photography. I did stick to the kit lens for a few months, just like pretty much everyone else did as a 50mm was a standard/kit lens in the past.
In those few months, I learned a WHOLE LOT. I learned about the different effects of focal lengths and apertures. What they do, what they achieve, their strengths, their weaknesses, and most importantly: how I can express myself in 2 dimensions. Sticking to the kit lens made me know what I wanted most in the beginning: a real wide lens. I started with landscapes. Knowing that, purchasing my next lens was easy. And the rest is history.
I know the usual arguments though: "better rendering, sharpness, distortion, optics", "you'll eventually end up getting this lens" etc but these don't matter to a budding photographer. You've got to focus on the PHOTO itself, all these little technical stuff will mean NOTHING if it's a bad photo to start with.
Once you know what YOU want/need, you can prioritize and plan your next purchases. I see a lot of people lusting over all these lenses without a real reason as to WHY, or more just for completion/coverage of all focal lengths. But then there's this whole LBA thing going on of course, and collecting beautiful glass is simply fun and addicting
I also have to admit that people tend to look down on you if you don't have expensive stuff. I remember people always looking at my gear at photography meetups. I started out with a Nikon D40 and a kit lens, and everyone was there showing off their D80s, D200s, D2xs with their expensive f/2.8 zooms and battery grips. They would ALWAYS look at my gear first and I just HATED that. A quick look and they'd gauge and judge me. Another thing I hate is "Hi. So what gear do you use?"
After a few of those times, I stopped bringing my stuff or just kept it in the bag. I also made it a point to not look at other people's stuff and make them feel what I felt. I want to get to know YOU as a PHOTOGRAPHER, not you and your gear. So I talk to them and make it a point not to talk about your gear but about your photos.
I'd feel so bad when people would tell me "Oh I'm just using a D40 and a kit lens" and I always tell them "SO WHAT?? It's the photos that matter. I've seen some of the most incredible photos with "just" a kit lens. Don't let that bother or pressure you, let them judge you for your photographs not your gear."
Anyway I guess that's it. I just felt like letting that out and I want to tell new people that a kit lens, or WHATEVER lens, Limited or not, is perfectly fine as long as you get the photos YOU want.
