The Lytro Camera

Technology advances everyday and it has become a way of life it seems. You buy a computer only to find out when you get home that you are already outdated. Cellphones, TV’s and of course, our favorite little gadgets: digital cameras, are all victims. Cameras are updated about every 12-18 months. They perform better in low light, the megapixels keep climbing to a point that it is pointless, they add 72 focus points on top of the 52 that was on the previous model… I get it. Upgrade. Upgrade. Upgrade. But it has reached a point where I think it is too much of an upgrade. Let me explain.

There is a little known company (right now) called Lytro based out of Mountain View, California and yes, this is where a once little known company and now ‘king of the internet’ called Google is from so this little town is packed full of innovative thinkers, designers and inventors. Lytro has an idea that will change photography and it is both very exciting and very scary. They are developing a camera that will allow you to change your point of focus after you have taken the photo. Yes, you read that correctly, I said AFTER.

Why is this so exciting? Well, think about this scenario. You and your family take a road trip to the Grand Canyon. When you finally get there and pick your jaws up off the floor from awe of how beautiful the canyon is, you ask another tourist to take a photo of you and your family with the canyon behind you. That kind tourist snaps the photo for you and hands you back the camera, then something amazing happens. A massive eagle flies by and you run off to take some photos of the eagle and completely forget to glance at the photo of you and your family with the canyon. Days pass, vacation is over, and you are now back home uploading all of your images to view them. You scroll through and then devastation ensues. That one photo of you and your family with the canyon is out of focus. You scream, break stuff and yell four letter words.

That scenario doesn’t sound too pleasing does it? Well, if that family photo was taken with a Lytro camera then you wouldn’t have a broken computer screen and apologizing to your children for those four letter words that you belted out.  You would be able to simply click on you and your family in the photo and magically you all come into focus. Ta-Da! Awesome, right? Well of course but this is where it gets scary.

Photography has now become one step LESS of an art form in my eyes. What will define a professional photographer from a novice? What will define knowledge of photography over automated photography? Yes, we have auto white balance, auto ISO and auto focus which help a lot of people but now with the control of your depth of field AFTER you make the mistake; that is too much ‘mistake correction’ in my eyes. I say learn your camera and lenses, learn how photography works and practice it. Do not relay on machines to correct your mistakes because you will never learn. That is what the scary part about the Lytro camera is. If this becomes mainstream, all the ‘old school’ photographers will be the only ones left in the world that know what depth of field is and how to control it.

So how does it work? Without getting too technical, basically this camera can capture a ‘light field’ which is the amount of light traveling in every possible direction. Traditional cameras can not capture all that light. The Lytro, however, can and thus, allows you to control your depth of field in post processing because all the light and information was captured from the beginning. Pretty cool, huh?
Do not get me wrong though, if I ever get my hands on the Lytro camera I will try it out and see what it can do. But when I am done, I am going back to my Nikon.  As a good analogy: You are not a chef if you cook everything in the microwave and the same goes to photography, you are not a photographer if you make zero decisions in your shot. Learn your camera people.

Nikkor AF 50mm vs AF-S 50mm

Finally, Nikon came to their senses and released an AF-S 50mm f1.8 prime lens. Why is this important? Well, for starters: it is an AF-S lens so for anybody that has an ‘entry level’ camera such as the D3000, D3100, D5000, D5100, D40, etc. then auto focus will finally be your friend on this one. The 50mm f1.8 prime lens is a very popular lens, especially for portraits. It is also one of their more inexpensive lenses which helped it become on of the ‘cool kids’ on the block.

Now the comparison of the two lenses: AF 50mm f1.8 vs the AF-S 50mm f1.8. Let the battle begin (insert loud stadium announcing voice with crowd cheers here)

Performance
Below you will see several test shots of each lens shot at different f-stops.

AF 50mm f1.8

You will notice the color hue casted over the images, especially the AF-S 50mm. No Photoshopping was done to the image but as you can see, the AF-S 50mm has more of a pinkish color cast on the image. My white balance was set on Auto and the two images were taken within 60 seconds of each other so there was no light change. The clarity on both lenses are supurb on all f stops. With the wide aperture of 1.8 both lenses will perform exceptionally well in low light situations and creates a beautiful ‘bokah’ effect. For the ones that do not know what bokah is, it is an effect where light sources appear as large soft balls of light in the backgrounds of your images. It can only be achieved by using a very wide aperture.

Below are two more examples of the two lenses shot at different f stops.

AF-S 50mm f16

AF 50mm f22

One big difference I found between the two lenses is the minimum aperture. On the AF 50mm version it will only go from f1.8 to f22. On the AF-S version it can only go from f1.8 to f16. So, the AF 50mm has a hand up since it allows you to have a greater depth of field. I have found myself using a higher f stop numbers lately and in this case I would go with the AF since it allows me to have that extra depth of field but shooting at f1.8 on both lenses is why you are buying this lens. It is what it was designed for.

Build

Both lenses are very small, compact and light and are some of the smallest in Nikon’s lineup. The AF 50mm is slightly smaller than that AF-S 50mm but not by much. But overall, the size and weight should not be an issue on either lens.

A nice feature and a ‘common’ feature on Nikon lenses nowadays is the switch on the side that allows you to change from Autofocus to Manual which is on the body of the AF-S 50mm. So you do not have to switch to Manual focus through the camera like you have to on the AF 50mm since that lens does not have that convenient switch. Also, do you like Nikon’s SWM (Silent Wave Motor)? If you do then go with the AF-S 50mm because it’s got it. It will be silent as a whisper when autofocusing and not sound as what I like to call ‘a remote control car’ in the old AF 50mm.

Conclusion

Overall, you can not go wrong with either lens. Both performed the exact same, no less than Nikon’s high standards. But they do have advantages over the other. The AF-S 50mm will allow autofocus to work on basically all of Nikon’s digital cameras, even the entry levels. The AF 50mm however will only autofocus on Nikon models D90, D7000 and up. The AF 50mm also has that broader depth of field to play with. The AF-S 50mm has the convenient A/M switch. So you may take your pick. So who won the battle? (Drumroll please!) I am going to say it is a tie. The timer ran out and they both were unable to knock the other out.

Spartan Photo Center has both lenses in stock so you can come in and test both of them out yourself.
