OK Darren. You've been perturbed when I've made negative remarks about Pentax as a brand or corporation, and have said that if only I'd used a K-5 I wouldn't feel that way about Pentax. I've explained that it would not have made a difference, as I was talking about the corporation and the Pentax 'ecosystem' not a specific product. Never did I denigrate the K-5 itself and neither have I the K-3, as I haven't used them Let's look at what you just wrote through the lens of intellectual honesty. > The new Sony cameras give you nothing other than the big sensor. You > give up the shake reduction. That's an interesting statement to make on many levels. The photography world is ablaze right now about these two cameras because of the expected image quality potential. They are loaded with features, and the FF sensors in such diminutive bodies is indeed the preeminent attraction. Your statement is such an obviously blanket statement it can't be taken seriously, The A7's like many other Sony's, Nikons, and Canon's do not have in body shake reduction. But implying the camera system is not capable of image stabilization is leaving an important point out. The virtues of both body-based and lens-based approaches to stabilization have been debated for years. Quite frankly, while I appreciate image stabilization, and would prefer body-based stabilization because of universality, it's not everything. Low light, it's helpful. Long telephotos or zooms, it's helpful. In many situations it does not make a difference and is still not as fool-proof as a tripod and mirror lockup (no mirrors of course on the A7's). > + Fullframe Sensor: K-5=no A7=yes Correct > - Autofocus: K-5=yes A7=no What? Both the A7 and A7R are autofocus bodies. The A7 has a hybrid phase/contrast detect AF whereas the A7R is contrast detect AF. To say the A7's don't have AF is, at face value, an incorrect statement. - Lens Correction: K-5=yes A7=no I'm not sure where this comes from and I searched for verification but couldn't find anything other than that Sony offers an app for lens corrections. However the NEX-6 and NEX-7 have built-in lens correction for native E-mount lenses. It would seem to me that Sony could or would continue this for native E-mount lenses. And of course ACR allows lens profile based corrections as well as manual adjustment. I'll admit I don't know the facts on A7 in-camera lens correction. > - Viewfinder: K-5=OVF A7=EVF There's been much debate on OVF vs EVF as you know. Many have no problem with EVF's and there's circumstances where they're preferable. It's a matter of preference or even just getting used to what the camera comes with. Basically if you can look in a viewfinder and clearly see the scene you wish to capture, it's doing the job intended. This can't be empirically categorized as a + or -. > ? GPS: K-5=optional A7=? Rather meaningless as it's an accessory. Who know's what accessories will be available in the future for the A7's? I'd say that for the vast majority of users, including myself a GPS on a camera is way way down on the list of must-haves. > - Image Stabilization: K-5=yes A7=no Addressed above. The A7's do not have in body stabilization, but to leave it at that without making the additional statement that lens-based stabilization is available with certain lenses, doesn't tell the whole story. > Other than getting a full frame sensor, everything else is a big downgrade. I'm not sure if that's your statement or of the fellow your quoting, but it's again a blanket statement - Made about specific products by someone (who I would guess) has not so much as seen them in person, much less picked one up and used it for any amount of time, has not experienced how the product handles, or examined the output image quality produced, since they won't be released to the public until December.
