SanDisk 2 GB Extreme IV CompactFlash Card ( SDCFX4-2048-901 ) Review

Average Reviews:

(More customer reviews)PRO: Very Fast, Allows more continuous shots without filling buffer
CON: Expensive
The SanDisk 2 GB Extreme IV CompactFlash Card is so fast, when I held down my shutter release (with Rebel XT set to Raw) for 3 fps continuous shooting, 30 seconds later it was still firing (it may have gone longer, but I just gave up and took my finger off the button). The Rebel XT is only rated for 5 or 6 Raw frames at 3 fps. Apparently, this 40 MB/s card clears the buffer faster than the pictures can fill it up. I also feel very confident that I can take multiple shots in succession even while the camera is set to both Raw and Large/Fine JPEG (at the same time) without worry that the camera will be busy writing to the card. On one outing, I took 101 JPEG pictures (approx. 3.3 MB each) and uploaded them to my PC via the Sandisk Firewire card reader in less than 30 sec (est.). Note that you probably will need the Firewire reader to get the full 40 MB/s upload speed (from your card to your PC). This card costs a bit more than the Extreme III, but it gives a very comforting level of performance overhead.
CONCLUSION: Best memory card available for DSLRs. Worth the money. Get the Firewire card reader if your PC has one of the two provided Firewire plug types. The Firewire connection on the front of my PC was not compatible, but the back one was.

Average Reviews:

(More customer reviews)This was a gift from my son last week to go with my Canon T1I.
Pro's
- Solid build and comfortable feel
- Expands on the camera's capability
- Holds 2 batteries so you can keep shooting during extended sessions
- Has an additional tray for using "AA" batteries in an 'emergency'
- Interfaces with the DSLR
- Setting are easily adjusted
- Several of the camera controls are remoted for easy use during portrait shots
- Off/On switch for remote buttons if you want to disable them for landscape shots
Con's
- Does not retain settings when the battery tray is removed (no battery backup). EDIT - IGNORE THIS CON STATEMENT AND SEE THE EXCELLENT INFO IN SUBSEQUENT POSTS REGARDING BATTERY BACK UP AND ORIGINAL BATTERY COVER STORAGE!!!
Minor irritation in the grand scheme of things since setting clock/calendar is
so easy
EDIT - I've now had this grip for almost a year and still love it, particularly after being corrected by subsequent reviewers regarding battery back up and, as a bonus, the original battery cove/door storage.

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.
