I've been contemplating a new camera body this summer. I've grown frustrated with how easily my sensor gets contaminated when I switch lenses all the time. By the time I finished the last cycle my Canon 60D took images that looked like they had chicken pox. I had to spend a small fortune to get it cleaned but I know that the dirt will return as soon as the next cycle begins. The only way to keep a camera clean is to never open it. But since I have several lenses (with another one being contemplated for astro photography) the only solution is to buy more bodies and commit each one to a certain lens. I'll do that for my 2 main lenses (the Canon wide angle and telephoto) and only swap in the astro lens when I'm doing night shooting. I'll have to set up a system for making those changes as clean as possible (maybe inside a big plastic bag to minimize environmental contact) and keep them to a minimum.
Anyway, I've been watching the camera market intently since January and it's become very interesting. Canon opened the bidding with their 5D SR, a 50 megapixel monster that sells for almost $4K. It is an interesting offering but has one serious drawback ... the same noise issues that plague my 60D. Canon sensors are just horrendously noisy and there's no getting around that. I'd need to get seriously dedicated to noise reduction and to buy some not so cheap software to help mitigate the issues this noise creates. But I'd at least not have compatibility issues with my lenses.
Sony offers the only serious competition for the Canon bodies. Their mirrorless design leaves room for adapters that allow the use of almost any lens from any manufacturer but, up until now, there were big issues. Auto focus was painfully slow and often failed so manual focusing was almost a given. That's OK most of the time but when you're trying to take candid photos (like on the street) it's a huge problem. And the image stabilization systems in most lenses didn't work very well either. It was a mess and, quite frankly, the first version of their high pixel count camera, the A7R, had some serious issues with shutter noise, vibration and lifetime. I know a lot of pro photographers made the switch but they were not all really happy with it. But, just this month, Sony introduced the next round ... the A7R II, and it looks like a game changer. It has a big sensor, 42 megapixels, so it competes directly with the new Canon but the really exciting ideas involve 5 axis image stabilization in the camera (by moving the sensor) and auto focus is now fast because they have 399 phase detection sensors spread across the sensor and they work with Canon auto focus lenses. I've seen several videos and the system is very fast indeed. They also seemed to be listening to their customers and made major changes in the software so HDR shooters have more bracketing options and video shooters can now shoot 4K internally to the camera. This last item is a huge advance ... a small camera that shoots ultra HD to the internal memory card (not everything is great ... only 8 bit and the color space is somewhat limited but still...). And the new sensor is very low noise so I can do my HDR thing and my star photo thing and even my video thing all with the same camera. Price is an issue ... $3200 ... and $399 for the adapter, but it's still a major step for them and for me. I can now get the resolution I want, a full-frame 35mm image and some really nice features that will make my life a whole lot easier. Now, all I need to do is find that $3600 and I'll be set to go ... hmmmmm.
Zion Virgin River Dream
Take the Zion park shuttle to the very last stop ... the Temple of Sinawava ... and take the path toward the narrows and you find the Virgin River. This river made the Zion Canyon and the narrows and pretty much the whole park so it's a big deal. In this area the river runs through a lot of rock fall, stuff sloughing off the nearby canyon walls, which makes for many turbulent pools and small waterfalls. It's an extremely picturesque area so I spent most of a day there. One place, in particular, caught my attention. Many rocks had pushed together to create an elevated pool which cascaded over the resulting dam and waterfall. I'm always looking for moving water as it gives me a chance to work with my 10 stop neutral density filter (here and here and you'll need an adapter ring to fit your lens). You've seen the effect I'm sure ... cascading water turns into the neatest mist. You achieve this by using this really dark filter which pushes your exposure times out to 30 seconds or longer. The result is an exposure that obliterates all evidence of individual drops and shows only a ghost of what's actually there. You get an image with some really sharp features (rocks mostly) and everything else is so ethereal. It's a really interesting effect.
Anyway, I spent quite a while at this waterfall and took many images. This one is probably the best of the lot although I'll develop all of them to make sure. This is a single exposure, extensively processed in Lightroom. I used several radial filters to highlight the rocks (especially the one in the middle) and worked with the colors to pull out the water and rock colors. Very dramatic I think.
