Originally posted by vinzer I'm just thankful that you're none too an*l about your system switch. I really do advocate people going with the system that suits them best, just as long as they remain classy over it.
I'd like to ask, though, if Sony has an implementation to get in-body IS to work with manual lenses like Pentax has (via entering the specific focal length). This is something that I was always curious about, since the Alpha mount is able to mount M42 lenses, at least.
Oh, and could you mail me a full-size photo of the A900 with ISO 6400? I'm none too convinced with the stuff I see over the net, and would appreciate one taken by someone who has skill and used in real-life situations. Or if that's too big to send, even just a portion of the photo that I could view to 100% will be fine. Thanks!
Oh, and I know it's not a fair comparison, but did you feel a big difference between viewfinders with the K20D and A900?
And vice versa, I'm a bit overwhelmed at the supportive response I've heard from the folks I've gotten to know here. We're all photographers first, even on a brand based forum - thats awesome. I have the utmost respect for you all.
I've made some fast observations about the view finder. It was a standout feature from a manual shooters point of view. I hope sharing my point of view on the topics you brought up won't be taken as a knock on the Pentax. In fact, I'd just PM'd James on the same topic, I'll cut and paste some of my response to him:
Two weeks ago, I would not have seen myself doing this. I spent a lot of time and research choosing those lenses but the most important thing I did was
learn and I'll always have that. I have to be honest, the K20 is a stricter teacher. Things like noise and motion blur appear more obvious cropped (vs larger image from A900) and thus loom larger on the final product as a result. Physically, the K20D is a stand-out. Its easily the equal (and better sealed) than the A900 in this regard, and its very well featured too. The Pentax at its price is a fine piece of kit and I do not regret my time with it, I learned a lot but I'm comfortable with the change.
The viewfinder turned out to be as important as the sensor in this decision. I always used live view on my K20 because I could zoom in and guarantee I was hitting my focus target, then I zoom out, compose and shoot. I'd fall back to the Katzeye view screen at times. I didn't mind working this way and with these tools I had improved my focus accuracy because shooting with the standard screen, I would compose my subject in focus, but upon inspection, hitting perfect focus was usually a crap shoot, especially at the apertures I enjoy. I'd accepted this as a way of working, made the best and shot (a lot!). Now I've realised in person why some people argue that even though there is no live view on the A900, its not as necessary. I've only 3 days of experience shooting with it so far, but I can state one of the keys to my confidence with the switch was the viewfinder/backscreen combo. When I focus on something in the viewfinder and shoot, its always exactly what I thought I was shooting. Simply, I instantly became more confident shooting with the A900 - yes, you can buy confidence, I've done it. This camera was made for manual focus, it is a relief but the K20 taught me better than this could have to start with. The back screen is a very good tool, very high resolution. If I were building a camera I'd always make this choice, it is eye candy, and helps to see right away that you've hit your shot and again, with the 24MP Exmore, noise and motion blur are 'zoomed out', so they have to be a lot worse to be unacceptable than with the K20 sensor. Thus, even if the K20 and A900 handled noise equally, you wouln't see it as much on the A900. 1600 real world is not a problem. As above, the K20 was a strict teacher by comparison. End result, my keeper rate instantly takes a big turn up, from composition and execution accuracy to final image care of the sensor, plus, plus, plus. There really is no going back for me, hence the decision to sell. I was hoping to buy this as a Pentax product but it seems they have another direction in mind, so I followed my personal flow.
I'll give you some samples when I get my Planar, then we can have an apples to apples. The 135 STF is rediculously sharp (check photozone), it'll skew things.
The mount for M42, in order to take advantage of the SR, has to trigger the AF conformation on the mount, thus a chipped adapter is required. This is an extra step not required with the K20, but it can still be done. I've ordered one that has four selectable focal range/aperture combos programmed on for $70 to use with my M42s. I guess the bright side is my Exif data will sometimes be more correct than before.
Anyways, I've got to run for now. Hope I haven't come across too strong in any way, I'm just hoping to share my decision.
Much respect,
Kelly.
