Review : Jenis Battery Grip for Nikon D5000/D3000/D60/D40/D40x, Professional
Brand : Jenis
Product Group : Photography
Due to the convenience of deleting unwanted photos and inexpensive media storage, we take a lot more photos than the film era. Today's digital camera puts a lot of stress and loading on the battery, hence the battery grip becomes an essential accessory to most of us. Jenis battery grip uses the same build material as the original manufacture on all its product lines, to ensure a long time trouble free operation with your beloved digital SLR camera. The build quality and ergonomic not only matches the original equipment, there are some added functions on the higher end products that are designed with the professionals in mind. The extra features are not available either from the original equipment or the other battery grip on the market. The S model (Standard) provides the same function/capability as the original equipment. It can take up to two Li-ion battery or 6 to 8 AA batteries (depending on the model) to provide extra power reserved for longer shooting time. Depending on the camera design, some can also increase the continue shooting speed. There is an extra vertical shutter button to provide easy operation when shooting in portrait/vertical position. The control wheel provides the same functions as the original control wheel with easy access when operating in vertical position. The P model (Professional) has all the features in the S model but with some advanced essential functions. There is a clock which not only display time, but also serves as a self-timer or long exposure shutter control that can provide up to 99hr 59min 59sec delay time/B shutter. The SD model (Super Dual Storage) has all the features the P model has except the remote capability, but adds two extra high speed CF slots for people who like to take a lot of photos on a trip. A larger B&W LCD screen is provided to display some of the important shooting information. The grip also does some basic file operation. A high speed USB2.0 connection is also provided.

Best of Class Grip for a Body that Wasn't Designed to Use One
By Mark J. Hanson
If you use your D40/40x/60 with large lenses, on long-all day shoots, or with gloves in cold weather, then you may find a battery grip very helpful in adding system stability. I shoot my D60 with a 70-200 f/2.8 tele, which I find difficult to balance on the D60's tiny body without more handle and heft. Since Nikon didn't design the D40/40x/60 with a battery grip in mind, we're left to choose among various third party options which are all of the same design, from the same wholesale manufacturer, and offer the same strengths and weaknesses. Of these, only the Jenis model appears to include additional time / intervalometer features. I chose it for that reason.
Strengths:
* well-sized, contoured, and, with batteries, weighted to provide the extra stability D40/40x/60 shooters may need;
* useful intervalometer and timer feature;
* additional shooting time with second battery--not really that big of an advantage, given that you can just carry a second battery around in your bag; but the additional battery does provide further ballast.
Weaknesses:
* construction quality isn't quite on-par with the camera body itself, even if the shape and contours do match;
* the intervalometer triggers only 99 frames;
* the intervalometer, stopwatch, and simple clock-setting are maddeningly complex and counterintuitive to set and use;
* the vertical shutter release, which fires via the body's infa-red remote trigger, is a kludgy solution. It works, but it doesn't allow for the main shutter's half-depressed focus / exposure lock; you also need to drill through the body's menus to enable remote shutter release before using it. (And, as other reviewers have noted, you need to drill the menus again to engage the main shutter release before switching back to horizontal use.) This problem is mostly Nikon's fault for not designing the D40/40x/60 with a real vertical shutter interface, so the grip's solution is the best possible workaround for the body.
Honestly, if you plan to shoot vertically and/or with huge telezooms most of the time, this grip's compromises around Nikon limitations really suggest that D40/40x/60 probably isn't the body for you--consider moving up to a D90 or have a look at Canon's EOS Rebels or Pentax's "K" series DSLRs, which can be extended with genuine OEM grips. But if you do plan on occasional vertical or pro telezoom shooting with your D40/40x/60, then this grip is your current best-in-class solution for improved system stability.

looks great
By bh
This fits like a glove on my Nikon D60. I can go all weekend and not have to worry about changing batteries. I does make the camera heavy but I don't mind. The size it adds to the overall camera fit my hands better. If you don't mind the added weight go for it. Great price. On the down side every time you take the batteries out to charge you have to reset the clock, I wish it would hold the time so you don't have to reset it.

Verticle and horizontal triggering cannot be used at the same time.
By Joey Joe Joe
I bought this grip for added battery capacity and interval function. I like the fact one can use AA batteries instead of the nikon packs. Fit and finish almost matches the D40 but the texture is a little off and the unit is a bit on the glossy side. Build quality seems very solid and I was surprised how well the IR led pops in and out (too bad it cannot be seen by the camera receiver). What I really don't care for are the instructions. OMG it is like they were translated to english using an online translator. Instructions aside, the biggest problem with this grip is the verticle trigger. The grip uses an IR led to control shutter actuations (even in interval control mode) so the camera must be put into remote mode. So forget using horizontal and verticle triggering at the same time. When I first tried the verticle trigger it didn't work until I realised the IR led was not in line of sight with the IR receiver on the camera. Seems like someone did not do their homework engineering this thing! It works if you use your index finger to reflect the signal while pressing the trigger. I added a piece of foil around the grip's led and it seems to do the trick. It is because of this flaw I ranked the grip as low as possible. Like I said, I bought this grip for the capacity and the interval function which works (provided you get the camera IR receiver to see the grips led). It is definitely not worth the original price which is why I am glad I bought it on sale. IMO there are better grips out there. As for the timer function it can only take up to 99 pics so look somewhere else if you need a more capable intervalometer.
