AstroScope Night Vision Module For DSLRs

9350eos-ff-339x281

Adequate light has always been a problem for picture taking, which is why someone made the mistake of inventing the on-camera flash, spawning generations of washed out pictures filled with creepy red eyes. A much better way to go about taking pictures in the dark is with a more sensitive lens, but the more sensitive the lens gets, the bigger it has to be DSLR Battery Grip .

You can get around this practical limitation by cheating and using electronic enhancement, and the Electrophysics AstroScope 9350EOS-FF night vision module makes this just about as easy as possible by mounting snugly between your DSLR body and the lens of your choice. You can use telephoto lenses, macro lenses, tilt-shift lenses… The AstroScope preserves all the electronic connections between your camera and your lens and just sits there, amplifying photons as they pass through. It works just fine with image stabilization, draws a minimal amount of power from your battery, and is available for both Nikon and Canon DSLRs as D40 battery grip and EOS Canon EOS 450D.

As far as price goes, Electrophysics thoughtfully answers that question in their FAQ:

Is the AstroScope expensive?

The AstroScope 9350-series products are cost effective modular solutions. We designed the AstroScope with modularity in mind to save you money and to “build in” a level of forwards compatibility Nikon D300 battery grip0  . You can take advantage of the unique opportunity to “swap” our patented Gen III AstroScope common module Central Intensifier Unit from one night vision imaging platform to another (for example, use one CIU for both a camcorder and an SLR camera setup).

The only other problem with this night vision module is that it turns the whole image that exciting high-tech military fluorescent green color like Canon EOS 350D battery grip , which might cramp your style if you’re trying to, say, take pictures of animals at night. The solution, of course, is to go find animals that are green to begin with. Like, polar bears.

Battery Grips for DSLRS

I recently made a fairly significant addition to my digital camera kit - a Canon EOS 5D. Ever since I’d tested the camera for a few weeks last year I had been dreaming of getting one of my own (and saving my pennies) so when I had enough money saved up I grabbed one.

Also rounding out the purchase was a new Flash and a Battery Grip.

While I thought long and hard about buying the camera body and the new flash the Battery Grip was something of an impulse buy. I’d previously always invested any spare money into new lenses and hadn’t thought about a battery grip - but there was an option to throw in the grip (and an extra battery) for only a little extra and so I decided to give it a go - thinking that I’d probably only use it if photographing an event like a wedding.

Having had the new camera, flash and grip for a six weeks not I can honestly say that I’m extremely pleased with each of the purchases. The 5D is a dream to use. My only complaint is the slower frame rate in burst mode. I’m also loving the ability to go extra wide with my 17-40mm lens now that I have a full frame camera. I’m also starting to wonder if I should buy a lens with a longer range than 200mm (as it has less impact on the full frame sensor than it had on my old 20D). I’m also loving the flash - it’s producing some great results and now I have the ability to set it up in a slave setup with my old flash I’ve been experimenting with some interesting lighting for portraits.

So the 5D and EOS 300D battery grip the new flash are great - but what has surprised me most is that I am really loving the battery grip. In fact instead of just attaching it to my camera for special events, I’m finding that I’m using it all the time.

My wife thinks I do it because it makes my camera bigger (and boys like to have big things - hmmm…. that didn’t quite come out right) and that I’m just showing off. Perhaps she’s got something there, it does make the camera look more professional - however I there’s a few other reasons that I love my new BG-E2N battery grip:

1. More Power - two batteries instead of one means recharging half as much. I find that Canon DSLRs have pretty good battery life at the best of times but after a couple of weeks of medium use-age shooting with the 5D I realized that I’d not had to recharge once (a new record for me). It was also great when shooting my son’s birthday party last week. No hunting for and changing batteries at key moments!

2. Second Shutter Release Button - I knew the Canon BG-E3 battery grip had a second shutter button and setting dial but didn’t realize how much I’d use it in my photography when shooting in portrait mode. It’s not that I ever found shooting in portrait mode difficult before - but this is so much easier (or am I just imagining things?)

3. Weight and Balance - two batteries weigh more than one and the grip itself adds a little weight and size to the camera. While this could be seen as a disadvantage (and I’m sure it would be in some circumstances) I really love it. I feel like the camera is sitting well in my hand and that I’m somehow more solid when taking shots. I’ve read people argue about battery grips helping combat camera shake and previously didn’t see how something heavier in a hand would help - but again I ‘feel’ like there might be some truth to the argument.

The only real downside of the BG-E5 battery grip is that while the extra weight and size feels good, it could get a little tiring - quite literally. I did shoot with my 70-200mm f/2.8 IS lens for a few hours last week. It’s not a light lens and with the extra weight of the 5D (as compared to the smaller and lighter 20D) plus the weight and size of the battery grip I did feel like I was lugging around something pretty significant.
