White Balancing Lens Cap Review

Posted on: 31 May 2007

If you’re like me, you’ve perhaps wondered about those little caps that you can screw onto the end of your lens that claim to help you get “perfect white balance.” Is there such an item? If so, what is the cost? Is the cost worth it? Well, I found an article where someone has done the research on those little white balance caps and you’ll be surprised with the results.

White balance is an age old problem that is becoming all too modern with so many people moving to digital SLRs. Today’s cameras all have a pretty decent auto white balance settings, from the basic point/shot cameras to the pro SLRs. There are also several “fixed” settings on many of the simple cameras and most of the SLRs like Sunlight, Shade, Cloudy, Fluorescent, Incandescent, etc. But as many of you may know, these settings are not always perfect, and sometimes far from it.

Color balance is a long, deep discussion that can go on for days. But here, we are going to talk about a series of products of the type known as “over the lens white balance caps”. You may have seen these from companies like with their ExpoDisc Digital White Balance Filter and the ExpoCap.

With the cost of the ExpoCap being around $80.00 and the ExpoDisc at $120.00 for my lens size, I decided to see what else was out there to compete with these products. With little effort, I found one from a company called Mennon that claims to do the same basic thing as the ExpoCap, but the price difference was extraordinary.

I searched on Ebay for “white balance cap” and was presented with over several products besides the ExpoCap. The one I found for my lenses was under $10.00 shipped! Could this be? Is it possible that a sub $10 item could compete with the $80 ExpoCap? I was anxious to see for myself. (Read the rest of the article to find out the results.) (via L7 Photo).

Thank you for the detailed review of this product. I just discovered the existence of ‘white balance lens caps’ today, but was appalled at the $60+ price for the one I found first. I googled ‘white balance lens cap’ and immediately found a listing on for a different brand for $5.95. The huge price difference made me suspicious, but the very next google entry was your review–of that exact brand of cap! I’m sold–and off to Amazon to place an order. Thank you!!!!
