Why I use filters instead of lens caps

In my photography early days, I was a faithful user of lens caps. Whenever I wasn’t shooting, I would snap the lens cap onto the lens. I considered this a safe way to care for my equipment. Of course, most of us also enclosed the entire camera inside its companion leather case. Yes, we were very protective of our precious equipment. And yes again, I spent a lot of time looking for misplaced or buying replacement lens caps.

When I acquired my first SLR at age 14, I quickly fell out of the habit of using lens caps. I may have inherited this trait from my photography mentor for whom I worked while still a student. John explained that removing a lens cap required too much time when you are trying to capture the action.

Instead, I began to using a filter on the lens to protect the front glass element. The filter prevents dust and dirt from accumulating on the lens surface. And the filter is easier and safer to clean. To this day I use either a high quality UV or Skylight filter for most of my shooting. Now that digital cameras have replaced film cameras I also notice that leather cases have all but gone out of style. I see very few them of them these days. But I do notice that many photographers still use lens caps to protect the glass in front.

I’m not here to make a political case for or against lens caps, only to suggest that filters offer more than dust protection for your lens. In addition, they can protect the front lens element from nasty scratches. Here’s my latest proof. I was carrying this camera into the house when it slipped out of my hand and onto the floor. As you can see the filter is shattered.

Of course my heart missed a few beats as I watch the camera as it hits the floor. However, after removing the filter I can see that the front lens surface remains untouched. In spite of the fall, the camera is working perfectly. Apparently the lens barrel took the brunt of the fall so I’ll have to repair the lens’ electronics.. But the glass is still pristine.

This isn’t the first time that I’ve had a mishap such as this. Actually, this is the third time that a filter has saved the front glass element of one of my lenses. This alone tells me that I should keep on buying filters for each of my lenses.

High Speed Photography and More

As I was walking the aisles of the PhotoPlus Expo, an impressive photo caught my attention. It was a stop action of a glass bottle as it was shattering into hundreds of small pieces.

I was at the booth of a company named Triggertrap and they were showing off its Redsnap trigger. This device is unique in that you can use one of several sensors to trigger your camera or flash.

 

This is the Redsnap. It accepts interchangeable sensors: laser, sound, infrared and lightning. It has three outputs to connect up to three cameras or flashes. A sensor snap into the top of the unit. In this photo, the sound sensor is attached which was used to trigger to sample photo of the breaking bottle.		this photo from Triggertrap website
These are a pair of laser sensors. A laser sensor can trigger a camera when the laser beam is broken. The Redsnap can also be set to take timelapse photographs.

 

The good news is that this looks like a promising product.

The bad news is that the Redsnap is not yet available. Triggertap has been raising money to build and distribute the Redsnap through a Kickstarter campaign. The goal was to raise £50,000 but they surprisingly raised £290,000.

I learned that the electronics and enclosures for the Redsnap are now being finalized. Small production batches will be available for Kickstarter contributors beginning in December and January and full production is scheduled to begin about May of next year.

Retail prices have yet to be determined. For more information go to the Triggertrap site.

It looks like an interesting accessory. I hope to review one when they become available.

Stop Lens Cap Loss

Honestly, I’m not a big fan of lens caps. In the field, I don’t want to remove the cap, put it in a pocket for safe keeping and then be get prepared to shoot. Nor do I want to dig it out of my pocket and put it back onto the lens.

Instead I’ve made it a habit of buying a good quality UV filter for each of my lenses. The filter is to protects the lens front surface from dirt, grime and scratches. I feel a lot more comfortable cleaning the surface of the filter repeatedly rather than the surface of the lens itself. To be fair, this is my preferred way of shooting and I know that not everyone subscribes to this way of working.

So how did we get into this round-about discussion about lens caps? At the PhotoPlus Expo last month as part of my reporting I received a Press Kit from show management. Inside were a few sample accessories courtesy of the exhibitors. One was these gifts was the Hufa S, a lens cap holder. Last week I took a few minutes to look at this product.
This small and clever accessory is made of hard plastic that’s fully covered with a soft rubberized material. The Hufa easily attaches to your camera strap without having to disassemble the entire setup. Instead the strap slips through the slots and is ready to use in seconds. WHen you remove your cap from the lens, you simply slip it beneath the large clip. The clip places enough pressure to hold the cap regardless of its size.
Here you can see how the Hufa S attaches to the camera strap. You can adjust the position of the Hufa S further up or down along the strap so that it won’t interfere with your handling of the camera.

There are actually two models: the Hufa and the Hufa S. The Hufa attaches to wide camera straps that are often found on camera bags. The “S” model shown here is for the narrower camera straps. Each model is available in three different colors: black, red and white. They are affordably priced at $10 each.

If you’re interested in buying one, please visit Hufa Holder.
