Thoughts on a Pentax k100D Digital SLR Camera

We are working on a review of Digital SLR cameras. I just got a new Pentax k100D camera. We will also be reviewing the Canon Rebel XTi, Nikon D80 and the Sony A100k Alpha.

Thoughts about the Pentax k100d:

It comes well packaged, pieces nicely protected. I got it with the 18- 55mm lens kit standard.

I popped in new ultra II sdhc 4.0 GB card from SanDisk, got a memory card error right away. Oh well, nothing technical is supposed to be too easy..

So I registered on line, did a quick google search and found i needed a firmware upgrade. The sdhc is so new, so big, goes beyond the the sd parameters, so the camera needs new firmware to use the high capacity card. I just love a camera that can be altered just by loading new firmware. kudos to pentax.

The process of upgrading the firmware in a Pentax k100D is pretty simple, if you have another old sd card around. You need at least 8mb. SO borrow a friend’s for an hour, or pick one up on ebay for 10 bucks. I borrowed one out of my Minolta Dimage z1.

All you need to do is copy the firmware upate onto the smaller capacity SD card and start the camera while holding down the menu key. It will walk installthe upgrade for you.

To find the upgrade go here:

This Pentax page has the download.
Save the exe file to your computer and run it. Its a self extracting EXE file , it will extract a bin file.

copy the bin file (a binary file with new firmware) onto an sd card. put the sd card in the camera with the power off.

then hold down the menu button on the left back of the camera and hold it while you turn on the camera. it should show you the old firmware version and then show that it is updating.

the camera’s screen has a litle image that says program update yes/ no use the up down arrows near the ok button to choose yes and just wait.
takes a few minutes to load goes through two phases, but has a fine little progress indicator so that you know what is happening. When you are done, take out the old sd card, pop in the new ultra high capacity card and you are off to the races.

Five minutes later i was ready to start learning and testing the camera.


Up and Running with the Pentax K100D

The Pentax k100d Digital SLR (DSLR) camera feels great in your hand. Definitely designed for a righty, with the the built in hand hold on the right side that has become a pretty standard design feature in all but the slimmest of digital cameras. The camera is definitely heavier than a little fixed lens zoom digital like the Minolta Dimage Z series. I’ll weigh them both and post it in another entry later. The balance is fine, no wobble to the camera. You can use it with one hand but definitely more stable with that left hand adding some balance.

I’ve been shooting with a Minolta Dimage Z1 with a 10 times optical zoom, and have mostly been happy with it. But its been just powerful enough to make me want a more substantial, versatile camera. My number one complaint with the simpler camera is stability and vibration. When you try to get an indoor shot, you often get blur or trailing motion. The Pentax is a Rock. Totally stable. No shake, no jitter. It has an anti shake setting. I was able to get ambient light, night time indoor lighting only shots of my daughters sleeping and playing with crisp edges.

Tonite I’m going to try to test another of its stability features: A 2 second delay on the shutter. Why does that matter? I’ve tried a number of times to get a decent nighttime shot of the Downtown Los Angeles Skyline from my deck. But even with a tripod I always get light trails. The Pentax manual suggests the problem might be the subtle rocking of the camera when i push the shutter release button and the internal mirror moves.

The manual suggests that if I use my tripod and the 2 second delay, the camera will have a couple moments to stabilize after i push the button before the image is snapped. I’ll let you know in my next post.

The camera has a batch of preprogrammed scene types where it will optimize its performance. Nighttime scenes, bright snow scenes, text on a page, sunset/sunrise, kids at play, pets, candlelight, and indoor flash prohibited locales like museums and school plays. Aimed right at the sweet spot of parenthood.

Took the camera out with me today to grab some shots and see how it plays out in the real world. Number 1: I love the camera’s speed. I have twin 4 year old daughters, getting them both looking the same direction and smiling can be a challenge. But with the K100d it is a breeze to just keep shooting and shooting figuring at least one picture will just rock. I got a dozen excellent shots today. When we kick this over to the blog and more formal review, we’ll post samples of some of the images.

Picked up some excellent macro shots of fresh picked roses. Clear enough to capture the sheen on the petals. Played a little bit with focus depths and with capturing a sunset sky. Limited by my own skill the camera’s images are stunning.

Pentax k100d Product Specifications

So far I love the camera. Images are crisp and clean, shake resistance works like a charm, and you can snap lots of images quickly.

My only disappointments so far:

1. I really need a longer lens to get decent images of downtown, sunset etc.

2. I wish I could also take video. My cheap little minolta lets me spin a dial and catch a minute or two clip of decent resolution video. so lots of times i don’t even carry my video camera. the K100d certainly could be engineered to do it, but it just isnt there. Probably enough to keep me from standardizing on this as my main family camera.
