6x Optical Zoom Lens For The iPhone’s Camera

Thursday, February 25th, 2010

One of the things most cell phones lack is optical zoom for the embedded camera. Sure, many of them provide digital zoom, but that’s mostly just enlarging a portion of the existing image and results in a lower quality photo or video. The people over at usbfever.com were kind enough to send me one of their products that aims to deliver the optical zoom we’ve been missing (for the iPhone, anyway).

iPhone 6X Zoom Lens

The iPhone Zoom Lens

The product usbfever.com sent me is a 6X optical zoom lens for the iPhone. It came with the lens, the snap-on case, a neck strap, a user manual and a microfiber cleaning cloth. I love when companies include the microfiber cloth because you can never have too many.

Although I found the user manual to not be all that helpful and ended up putting it aside, it really isn’t necessary for this product, in my opinion. The application of the case is pretty obvious and the lens just slides into the case. I will probably never use the neck strap. The lens does not have protective covers for either end, so it’s best stored in the box it came in which is small enough to keep in the car without being in the way.

The best test of a product like this is to snap a regular photo and then one with the lens from the same spot, so that’s just what I did. In my conference room, I snapped the first photo without the lens and the second with it attached. Both photos were taken from about 4-5 feet from the subject, although this lens kit would be most useful outdoors.

As you can see, the lens did a great job of bringing my subject a lot closer in the shot, but it came with some fuzzy edges. I think I could have adjusted the focus a little more, but it was a little awkward to do because the lens has a just a tiny little bit of room to move in it’s connector. I had slightly better results as shown in the video below.

Initially, I also had a hard time removing the case from my phone, but I had less trouble with it after I found that it’s easier to start from the side edges and work your way around. I think the case design could be better if the lens connector wasn’t glued on. If it was, instead, part of the molded case, I’d just keep the case on the phone all the time. With caps for both ends of the lens, I could then carry the lens around more freely and slap it on the phone in an instant for a quick zoom photo.

In any case, as is, the product does as advertised and is a pretty cool addition to your iPhone accessory collection.

Conclusion

This product really feels a little more like a cool novelty than a practical accessory, but it’s also under $20, which makes it a very affordable novelty item. That said, it is a pretty cool thing to have handy when you want to get a photo or video with your iphone and need to zoom in. The low price is certainly a selling point for anyone who needs a little convincing that they actually need a zoom lens on their iPhone.

Chinavasion’s Zoom Video Camera Gets in Close

Thursday, January 1st, 2009

Just before the Christmas, Chiinavasion, an electronics wholesaler, sent me a unique little video camera to review. It’s their MPEG4 digital video camcorder with “telescope style 8x optical zoom lens”, and it turned out to be more than I anticipated at first glance.

The box everything came in was nondescript, small, and was packed with everything needed to get started. Included was the camera, the 8x optical zoom lens with a lens cap, a US plug converter, an AC power cable, battery, USB cable, TV out cable, remote control, headphones, software, manual (in Chinese and English) and a carrying case. The camera includes a built in microphone and speaker, a 3 inch TFT LCD screen that folds out to view and can be flipped 180 degrees for self-protraits, a 5 Megapixel CMOS image censor and a 12 Megapixel max resolution (interpolated).

The big marketing draw for this camera is, of course, the 8x optical zoom lens, so I started playing with that right away. I quickly reminded myself how useless that level of zoom is in my house, so I headed to the top of a building. The camera’s built-in lens is threaded, allowing the zoom lens to simply screwed in. Once attached, the lens focus is adjusted to get a clear picture. In the video below, I pointed the camera at a nearby neighborhood, attached the zoom lens, and pointed it back at the neighborhood, revealing a lot more detail than before. I tried to edit the video, but Windows Movie Maker hates me today. You can also take a look at the unaltered video file right here (22MB). This camera also has built-in 4x digital zoom controls on the back. Unlike the attachable zoom lens, which is 8x or nothing, the digital zoom is adjustable, but I generally dislike using digital zoom as it tends to pixelate the image.

The camera does more than just video. When you turn it on, you can switch it from “Video Camera” mode to “Camera” mode for some pretty decent still images. I took a few to show the color and clarity with and without the optical zoom lens attached, but I also wanted to know how this camera measures up against my Sony DSC-P41 point-and-shoot camera and my new Canon Rebel XTi DSLR camera. None of the pictures below will win any awards, but they offer an interesting comparison. The LED flash from the Chinavasion camera puts out a pretty bright, whiter, light, leaving me with a whiter photo.

One thing I found unique with this camera is the included remote control. With it, I can take a group photo and be in it without trying to sync up to a timer. Better still, I can take 4 or five in a row without moving, just to make sure I get it right.

Beyond video and still image capturing, this camera includes four additional functions. You can play back videos and images, record just audio, and play MP3 audio files, essentially making it a full personal media player as well as a video and still camera. The MP3 player doesn’t offer any special features beyond choosing a track and playing it back, but it IS a video camera, so just playing the MP3s seems like it should be enough. The audio recording is simple enough, as well. You enter the “Record” mode and hit the shutter release button to begin recording. Then hit it again to stop. Since the audio files are stored in the same folder as still images and video, you have to head to “JPEG” mode to review what you’ve recorded.

A final mode is “Setup”, which allows a lot more custom settings than many cameras. In the Setup mode, you can change the flicker frequency, beep alerts, time, media selection, language, power settings, TV mode (NTSC/PAL), logo display, brightness and format the storage. Additionally, you can hit the menu button to reveal even more settings for resolution, frame rate, audio and white balance when dealing with video capture. The still image capture menu allows you to modify capture mode (with timer option), date stamp, flash mode, scenery, EV (for a darker or lighter image), quality, resolution, white balance, color (normal/sepia/B&W), and quick preview. In JPEG mode, you can rotate, lock or delete images from the menu, and the menu button changes the playback mode for MP3s.

The camera itself has a good weight to it but it’s still comfortable enough to carry around. Because of the weight, I’d hate to drop it as I’m guessing the plastic casing would crack if dropped from standing eye level. Although the zoom lens comes with one cap, I’d love to have one for each side, or maybe just an extra space in the carrying case for the zoom lens to keep it protected. After two weeks, I still haven’t tried every feature and function, but I’ve seen enough to consider it a pretty good deal for the price (about $110 wholesale from the site).
