Sony A65 24.3 MP Translucent Mirror Digital SLR With 18-55mm Lens Reviews

This is a serially (and extensively) revised review, as I have had a chance to spend over a year with this camera. It has stood the test of time. With only very few limitation (outlined below), it takes superb stills and very good video. JPEGs print out sharply at 30 by 20 print sizes (as long as I stay under ISO 800). RAW images at low ISO will print tack sharp to 36x24. When paired with the new Sony 16-50mm 2.8 lens (see separate review for this terrific lens), takes some of the best pictures this side of a FF pro camera - if you stay to ISO 800 and under. The one Achilles heel of this camera is low light noise, but I mostly avoid shooting at anything over ISO 1600, so this weakness is mostly rendered a moot point, and is also mitigated by the excellent sensor-based image stabilization (which gives a 2 stop advantage and works with ANY lens). This means that the A65 has low light capability of a camera that can shoot at ISO 6400 but has no IS. For those shooting in the virtual dark, see body text for comments (and confessions). And for those curious about the cryptic header (that this isn't a DSLR), it is a DSLT - meaning that a fixed translucent mirror that doesn't move replaces the standard SLR mirror that has to flop in and out of position in front of the sensor. That design difference is the key to the camera's unique strengths (and its weaknesses in the minds of many purists). However, that single design difference allows the much faster and more accurate phase detection autofocus system to be working all the time, including while shooting movies (something no other DSLR can do), and thus gives you full time live view, much faster hi-speed shooting, and a lighter body, but also requires an electronic (non-optical) viewfinder, and with a modest loss of light to the sensor (with some attendant noise penalty). The key issue is whether that balance of pluses and minuses works for you . . . . but for most people looking for the best possible still photography and video, this is, at least in IMHO, a truly brilliant stroke that in one fell swoop removes some of the chronic limitations of the classic DSLR environs. There are a few downsides, but with HUGE upsides. Whether its mix of features works for you might depend on what and where you shoot . . . . Pros: 1) Best viewfinder in the sub-frame world (2.4 million dot OLED), as bright as any full frame viewfinder, and with far more useful information. Once you've used it, you may not be able to go back, and optical viewfinders seem frankly primitive and confining. 2) Class leading 24 megapixel resolution (at low to medium ISO, yields remarkably detailed images, esp in RAW). Good dynamic range and color from this sensor (but see last update). 3) Many useful shooting modes including panorama and high dynamic range modes (but see cons on panorama mode). Intuitive and yet deep & customizable operating system. But can be put in simple AUTO and AUTO+ modes for the less technical. 4) Full-time live view system and full time phase detection AF for both stills and movies - FAR better than the clunky live view systems `tacked on' in traditional DSLRs, and the contrast detection DLSRs have to use with mirror-lockup during movie shooting. 5) Class-leading video resolution (1080 at 60p) with as good video capabilities as most camcorders. Typically excellent video if shooting in 60p, and with option to use either viewfinder or LCD for framing video - something no other DSLR can do. 6) Intuitive and well thought-out ergonomics. 7) Fast and responsive operation. Fastest continuous shooting in class (10 frames per second). Fast focusing, decent menu speed (improved w/new firmware) 8) Excellent image stabilization system in both stills and video (and no more rapid sensor overheating from the IS being engaged during video shooting that plagued the Sony A55). 9) In-camera GPS (can be defeated). 10) Decent battery life (significant battery upgrade from the Alpha 55) given that EVF sucks down a lot of battery. 11) Perhaps as good features/price ratio in the middle to high-end consumer/prosumer group as any model. 12) Easy access to any Minolta lens and a decent selection of Sony lenses for reasonable money, particularly a superb new 16-50 mm 2.8 lens (see separate review). 13) Ability to remove virtually all CA, distortion, and vignetting in increasing number of Sony lens (firmware-based). When used with new 16-50mm 2.8 lens, produces very sharp images, w/out any visible classic optical distortions (CA, vignetting, barrel distortion, etc). Firmware correction of classic lens optical aberrations has to be one of most under-appreciated but valuable features of this new camera's operating system. These corrections work with many popular Sony lenses (now available for virtually all the Sony kit and telephoto zooms and most Sony primes), w/ more included in future firmware. Software correction makes a VERY discernible difference in large prints, and means that these classic distortions are basically a non-issue for corrected lenses (see DP Reviews treatment of this). Cons: 1) Some increase in noise at higher ISO, particularly in RAW images without NR (noise reduction). Not surprising in view of increased pixel density (see #9 below). But this is clearly the camera's one major weakness, and no sense in glossing over it. 2) Despite six firmware updates, several which were supposed to address this, both built-in flash and external flash (Sony's HVL-F42) still yield consistently overexposed pictures. Can be easily fixed with exposure control but this shouldn't be happening. 3) As great as the EVF is, sometimes the view is too contrasty, yielding either blown highlights or `blackout' regions - needs contrast adjustment function. 4) Not as svelte as the Alpha 55 (but for those with big hands, the extra heft and size work). Quite hefty with the 16-50 2.8. 5) Limited control options in high-speed shooting modes and in movie modes. 6) Screen blacks out once you fill up the buffer in high-speed shooting and you have to wait until all the images are dumped onto your card with poor buffer depth (common problem across Sonys - even the new A99). Why can't Sony get this fixed???? 7) Resulting loss of live view in high-speed shooting modes can make aiming the camera a bit tricky. 8) Switching between viewing photos vs. videos is still a bit cumbersome and awkward. 9) Default JPEG settings are both too smooth (need sharpening), and at the same time rather noisy at higher ISO - requires users understand menu options and make adjustments to get best possible JPEGs (set NR to high on high ISO, and sharpening to 3+ gives you the best JPEGs without discernible artifacts in JPEGs). 10) Sweep panorama modes often poor in resolution (because of having to remove panning effects and image smear with very high shutter speeds and high ISO?) compared to stitching together your own panorama images from discrete images (i.e. using Microsoft ICE). Sony should fix this as it limits a very useful mode - should be an option to use lower ISO and hold the camera still and move through field of view instead of rapid panning. 11) Although the EVF is generally excellent, view becomes noisy in low light. 12) Video in low light can be under-exposed, and camera will not go above ISO 1600 for video shooting. BEST IN CLASS SPECIFICATIONS? Although the Sony Alpha 65 might have flown under the radar in the context of the simultaneous release of Sony's flagship Alpha 77, I believe it's actually the better deal for everyone who's not interested in a pro-style body. It contains most of the high technology of the flagship model Alpha 77, minus the top LCD panel and the 12 frame per second shooting rate (you'll have to suffer along with a measly 10 frames per second), a less complex AF system, and a few other minor `downgrades'. But the sensor and the EVF (in my judgment, the most important innovations of the A77) are intact. All this for a significant reduction in Price ($949 for body only versus $1449 for the Alpha 77). (NOTE: both prices have come down). If you're interested in video, there are few cameras that equal the video specification of this camera, as most DSLRs will only shoot in 60i (often times interpolated from 30p), whereas this camera will shoot a true 60 frames a second in progressive scan. Still pictures are spectacular, with more resolution than virtually anything outside of the full frame 24 megapixel Nikon D3X. A large 19x13 printout of a standard test image from DP Reviews studio scene shows the A65 very, very close in resolving fine detail to the Nikon D3x (the previous resolution king in 35mm photography prior to the Nikon D800 and able to resolve detail comparable to 35mm Kodachrome 64). LOW LIGHT PROBLEMS? Although the recent Digital Photography Review (the closest thing to a definitive reference source on digital cameras on the web) slammed the Alpha 77 (same sensor and basic image engine as the A65) for its high noise particularly in RAW, and its somewhat `mushy' JPEG rendering, while I generally agree, some clarifications are called for. First of all, the default JPEGs can be significantly sharpened. I run the camera in the 'standard mode' (one of several `creative modes') but with sharpening at +2-3+. You wouldn't want to do this with a Canon (they are already a bit `crunchy' in terms of their default JPEG settings), but there is no artifact effect that I have been able to find (excessive smoothing in the default JPEG definition?) and this adjustment gets much closer to the maximum detail out of the 24MP sensor. Also, one can also set the HIGH ISO NR (noise reduction) to high, instead of its default. Read more ›. this is my Sony A65 24.3 MP Translucent Mirror Digital SLR With 18-55mm Lens reviews
