Abstract Started photography with Pentax K-X

Welcome to the hobby and passion that can be photography. The K-x was my first dSLR when I got back into purposefully making images again since using a film camera in high school. My father shot Pentax in the day, and my father-in-law also was shooting Pentax at that time. The K-x is compact, renders well in low light, and is simple to use while offering a good set of advanced options. It allows the photographer to concentrate on the shot, and less on the tool. I am sure you will enjoy the K-x for quite some time to come. And yes, this forum is a wealth of knowledge and support. It will help you to grow in your own understanding, and allow you give back to others as you explore and discover. Cheers !

Is K30 "better" then the K5?

Today I was able to handle both the K-5 and K-30 at a local shop and while I am not as emphatic as Chex, I too found the K-5 to be ergonomically a better fit for my hands. I love the depth of the grip of the K-30 and it's "stick", however it requires pulling my shutter finger "back" towards the shutter, or holding the grip in a more shallow fashion. With the K-5, my shutter finger is naturally on target. Likewise, the rear wheel needs to be manipulated at the first knuckle of my thumb with the K-30, wihle the K-5 falls naturally under the meat of the thumb itself. I also find the placement of the K-30's Green Button and EV adjustment awkward, whereas the K-5's EV and ISO buttons naturally fall under my fingers without fumbling for them. As a K-x owner, one of my bugs is the shared button with Flash and Delete. I can't count the number of times I am quickly trying to delete a photo only to miss-time and flip up the flash instead. The K-30 shares the Delete and LiveView button. I can only imagine I would be initiating LV instead of deleting in similar circumstances. The K-5 has dedicated buttons for many functions, rather than shared functions. Overall, I find the K-5 to be more comfortable and better laid out for my hands.

I was able to put my Sigma DC 17-70mm f/2.8-4.5 and EX 50-150mm f/2.8 HSM II on both bodies. I snapped off a few handheld RAW shots at the short and long end of each lens, at a few different aperture's with constant shutter and internal NR shut off. The K-30 shoots RAW in DNG and the K-5 was recording in PEF. In my subjective experience, the K-5 tends to under-expose slightly relative to the K-30, and where aperature and shutter were the same, the K-5 at times opted for a higher automatic ISO (take this with a grain of salt). I did find the K-5 IQ to be a bit sharper at higher magnification and the noise to be smoother and more uniform. I also found this with the photos from image-resource, however I was using shake-reduction on both bodies, hand-held. Does the K-5 provide better shake-reduction ? This might account for the "sharper" images according to my pixel peeping. One would need to turn shake reduction off and use a tripod to rule this out, however the general patterns seemed to be the same as i what I have seen online. In terms of autofocus, both bodies were quite quick relative to my K-x. While the K-30 "seemed" to be potentially quicker, I can't objectively establish this to be so. I did like the focus peeking feature of the K-30. The K-30's shutter sound is quieter than then K-x, but louder definately than the K-5.

I will look forward to a more professional review from PF that is apparently coming out hopefully next week.

imaging-resource got back to me to confirm that they did use the same reference lens for both the 2-year old K-5 still-life shots and the current K-30 still-life shots FYI.

I too am in the position of having to decide between K-5 or K-30 as an upgrade to my current K-x. I was interested in the dimensional and weight differences, so I examined the user manuals online and tabled the percentage differences, as I find that a useful metric in thinking about these things. Weight based upon presence of batteries and SD card (kind of useless without them). The K-x gives weights for lithium and alkaline batteries, so I just averaged the two.

Width Height Depth Weight
98.1% 99.5% 98.0% 87.8% K-30 relative to the K-5
93.5% 94.3% 92.5% 80.8% K-x relative to the K-5
95.3% 94.8% 94.4% 92.0% K-x relative to the K-30

Dimensionally, the K-30 is as close to the K-5 as anything, however there is a substantial difference in mass. A bigger difference in weight than between the K-x and the K-30. Does the magnesium alloy shell account for the weight difference of the K-5 alone, or are there other factors in the mass ?

Having a bit of weekend fun with the K-x and some Sigma lenses in the kitchen. The first was with my favorite walk around lens, the Sigma DC 17-70mm f/2.8-4.5 Macro. The close focus is great to have, although it would be nice to get a dedicated macro lens at some point.

The next one was taken using the Sigma EX 28mm f/1.8. This is my "normal" lens on the crop sensor. I want to get out this summer and do some street photography with it. But today, more flowers !

And last, this one was taken with the Sigma EX 50-150mm f/2.8 DC APO HSM II which I recently picked up. Wanted to use it for portraits and indoor sports. Great lens, although I am so used to what seems to be a closer minium focus distance from the Pentax-DA 55-300mm f/4-5.8 ED.

Johnny managed to prove Newton's First Law, that an object at rest, stays at matter how uncomfortable that object is.
