Originally posted by Tanzer I am using Lithium AA's in my *istDS, you should go that route. From the manual, it would appear that alkaline AA's were really intended just for emergency use. I have nothing against Li-ion batteries, just the proprietary form factor. It's good that Pentax has used the D-Li90 in so many cameras including now the K-3 but I couldn't predict the future when I bought the K-5 and battery grip.
A truly versatile DSLR could operate as well with the mirror up as well as down. It's just that they are presently optimized for operation with the mirror down.
I agree with you about the EVF, but that's the only real core advantage, and as you pointed out, it's not always an advantage. It isn't so much of an advanced technology as it is good processing and software. A DSLR could use an EVF (in theory) or use a hybrid optical/electronic viewfinder but I would not think that is likely to happen since the OVF still has so many advantages for stills shooting, and Ricoh in particular is so proud (rightly so) of the Pentax OVF.
When I look over the progress that the other guys have made over the last few years it is astounding
for them, but in the end, their product has not overtaken the traditional DSLRs, except in video. And that could change overnight, if you believe what certain people are saying about the Nikon D810 video quality, for example. If Canon
wanted to, they could put C300 functionality in a T6i, they have the engineers, patents, and know-how to do so.
The *istDS did well with eneloop rechargeables, but they are expensive (more so than the non-original D-Li90) and require a more expensive charger so that they don't get damaged. Plus they are heavier and bigger despite having lower capacity. Lithium AA's cost a fortune IIRC... one set for the *istDS costs as much as one D-Li90...!
I'd say a mirrorless camera can be more robust, faster, have less shutter lag, less noisy, smaller, have a better preview of what you'll actually get in the photo (plus review in the viewfinder), allows for smaller and lighter lenses (and thanks to the new APS-C sensor in the NX-1 it doesn't matter if the light hits the sensor at an angle), larger viewfinder, allow you to see a picture even when it is too dark (as long as the sensor is sensitive enough, say for example the A7S), ... A hybrid might be possible, but what's the point? The only advantage is that you have a screen in the viewfinder. The 5 ms lag the NX-1 has should pretty much negate that advantage of OVF, the lag should be so small that you might not notice it. What's left is resolution I guess, but maybe it is already THAT sharp. While I haven't seen an EVF that has 100% convinced me, I don't think it is far off. If they'd be able to put my smartphone screen into the viewfinder, I'd be happy.
The D810 and the D750 are supposed to be really good, as far as DSLRs go, but they lack in resolution. The A7S and GH4 are tough competitors (it seems like Sony's colors are a bit... wrong, but that can be fixed in post), and the NX-1 looks like it will also be a very strong contender. Would it be possible to bring DSLRs to the level of those cameras? In parts, yes (video AF not so much, unless you use a sensor with PDAF sensors on the sensor, however you'd have to have the traditional placement of PDAF sensors too). But DSLRs are mostly covered by the really conservative brands, who don't want to or can't innovate.
Of course Canon could make a great video DSLR, but please, why would they?! Instead of $600 for a video DSLR they can charge $12000 for more or less the same hardware (yes, there's more to a C300 etc., but I highly doubt that those differences make up for $11400, of course they'd much rather sell the really profitable camera). It's funny that Pentax doesn't look at that and say "mh, we'd like to have a slice of that".
