Lens•Lab

I'm a pro photographer and trainer in Sydney Aust. I bought this app a few weeks ago and it's the best dof/hyperfocal tool I've ever seen. I use it on a daily basis and my students absolutely love it. If you are a pro, amateur or just starting out, do yourself a favour and buy this amazingly helpful app. It rocks!!! Works like a dream even on the new iOS 7. Thanks Lens Lab crew

Works really well at getting new photographers to understand what there cameras and lenses can do. Great for learning about optics.

Hello, I think I was accidentally charged 3 times.. once for 2.99 that went through immediately- once for 3.27 that is pending and once for 7.65 which is also pending. It doesn’t specify where form it just says Apple but they all came through at the same time 12:55-12:57 a.m. I’m not sure how to reach the merchant about this issue, but other than that, helpful app so far!

Love the app, it’s been very instructional. Any hope for medium format sensor support in a future update?

Love this app for the visuals. Makes teaching dof much easier. Any chance you could extend field size above 35mm to 120, 4x5, 8x10, etc?

Wonderful app. I’ve used it now for several years and I love it. If you want to know FOR SURE what portion of your photo is going to be in focus, this is the best app to see how changes will affect your depth of field. One great discovery was that by going wider, you get more depth of field. Since many current cameras have high megapixel counts, cropping some of an image off of “the sides” is not an issue. Awesome!

The new functionality that changes the granularity of your slider movement as you move vertically is very helpful, and mitigates a long-standing issue I had with this app. I just hope that this enhancement is easily discoverable for new users!

Every time I open the app it crashes the moment I touch my screen. It worked for a few settings then started to crash. Force quit the app yet it continued to crash. I restarted my phone (and to be honest, at that point I was done with this app) and it continued to crash a first tap. This app is less worthless as it cost me three bucks. Don't buy it.

As a photographer and trainer, I'm often asked about lenses and how they work. Sometimes people get it, with just a few sentences. Sometimes it helps to show them instead. This is what I use to show them. Whenever I show the other trainers, they end up getting this too. I don't use it all the time, but when I do, I'm glad that I have it.

This app really helped me realize why I was missing focus so much on a Nikkor 135mm f/2, I hadn't realized that unlike the lenses I'm used to, the DoF at 135mm, and about 10 feet is razor thin unless I dial the lens up to f5.6 or f8. The app now looks great on apple's latest phones too.
