Some discussions on this board got me thinking about the evolution of photography over the last few years.
Now, I am not suggesting that lenses are irrelevant, not suggesting that nobody ever needs more than the kit lens. Certainly, a wide angle lens won't give you telephoto shots. A telephoto lens won't give you wide angle shots. A regular lens isn't going to give you close-up bug macro shots. A 1.4 aperture lens will perform far superior in low light than 5.6......
But for non-professional photographers, is there really a critical difference between a $2,000 lens and a $200 lens?
For example, I shoot Sony.. they have 3 50mm prime lenses:
Zeiss 50/1.4... $1500
Sony 50/1.4.. $450
Sony 50/1.8 -- $168
Will the differences between a $168 versus $450 versus $1500 lenses really make much difference for most people?
So without further ado, my own analysis of whether lenses matter anymore..
Lenses matter more than ever
1. If you pixel peep, looking at images at 100% size, then today's 24-36 megapixel sensors are more demanding than ever. Lenses that may have been fine on film or 6mp dSLRs, may not resolve full detail for a 36 mp image.
2. Technology has added new features to lenses that may be worth paying for. Silent focus motors are great for video. In Canon for example, only some lenses support phase detect video autofocus on their newer cameras.
3. With the increased quality of camera phones and point and shoots, premium lenses can still help interchangeable lens cameras really stand out in quality.
Quality lenses matter less than ever
1. With improvements in sensor technology, a photographer has more ways to capture the shot. 15 years ago, a 2.8 lens may have been the only way around bad lighting. But where cameras today can shoot cleanly at ISO 6400 or higher, that 2.8 lens is less critical than it used to be.
2. Even simple post-processing combined with high resolution, gives the photographer a lot more leeway to get the final shot. A 200mm lens versus a 300mm lens? With a high resolution camera, you can easily crop that 200mm shot to get the same final product as 300mm. (Of course, can't go in the other direction).
3. Many of the differences between that $1,500 lens and the $150 lens will only be apparent if you pixel peep. If you aren't looking at the images under a magnifying glass, you won't really see any difference. If you are printing 8X10 or smaller, or posting pictures on facebook, you won't see any difference.
4. Cameras and software can correct flawed lenses in ways that used to be impossible. For example, some advantages of a great lens compared to a moderate lens may be: Less distortion, less vignetting, less chromatic aberration. But those flaws are generally easily corrected in just a few seconds of post processing these days. Some cameras can automatically make the corrections in jpegs.
My personal conclusion
Certainly, a professional photographer has as much reason for premium lenses as ever. But for many hobbyists and amateurs, I no longer agree with the conventional wisdom that "lenses always matter the most."
Many photographers may see a more dramatic improvement in their photography, at lower expense, with a better camera body, or by investing in a good flash and lighting accessories. (for great portraits, a few hundred dollars on a speedlight and accessories will serve most photographers much better than buying a $2,000 lens).
For example, take someone who has a Canon Rebel Xti, purchased in 2007. They want to shoot some low light sports... dance, gymnastics, karate.. etc. They aren't shooting for magazine covers, but they want to post some nice shots on Facebook for the grandparents to see.
They can purchase a Canon 6d for $1750 (new, cheaper if refurb). They can add the 70-200/f4 L for $700. So total for the lens and camera -- $2450
Or, they can keep the Rebel Xti, and buy the Canon EF 70-200mm f/2.8L IS II USM for $2500.
So for the same price, the full frame camera plus good lens... or keep the old camera and add the ultra premium lens?
I dare say most amateur photographers would be far better served with option #1.
Now, that's a rather extreme example. But I think it tends to hold true even on lesser levels. The differences between mid-priced lenses and ultra-expensive lenses are not really necessary for most amateur photographers, most of the time.
For myself, it's a matter of training myself to stop pixel peeping!
