Sony lenses that are accessible to me are crap. Nice images. Cheap, but cheaply made. Plastic mounts. Flimsy focus rings. Lightweight, sure and that has its benefits but one drop and…..
This got me searching for some comparable Minolta lenses. Love! Metal mounts, brick-like build, brick-like weight (maybe that’s not a plus), and the colors! The creamy bokeh! My collection was unmanageable. I had to let a few go. I now feel compelled to shine a light on a few of them while they’re in my possession.
The “Beercan” is probably the most well known of Minolta’s first generation AF glass. It is heavy. 70-210mm and a constant f4 is a pretty nice feature set considering ebay prices go around $150 US dollars. The autofocus is driven by the camera’s in-body motor and the glass is propelled by a screw. The zooming is in body so the barrel doesn’t extend as you zip across the range. It’s pretty long though and looks obscene mounted on the a77 without a grip. It’s sharp from around 5.6. The focus ring is narrow and not the best for full-time manual adjusting.
The “Beercan” produces much better IQ than the “Big Beercan” (75-300), is faster than the “Mini Beercan” (100-200) and has more reach than the “Baby Beercan.”
In the Sony/Minolta world of cameras, it’s a must have. It is legendary.
The a57 was a world opener for me. The video I was able to capture was remarkable and got my creative juices flowing. For inspiration I swallowed the addictive drug that is YouTube and Vimeo. I knew I needed more glass (lenses), faster glass (smaller f-stop) and wider glass (16mm or below on the aps-c crop). Sony makes a well-regarded 16 – 50mm f/2.8 lens (through the whole range!) with SSM that goes for $800. This is relatively cheap considering the Zeiss equivalent goes for $2000 and is universally agreed to be on the same level (minus the Sony’s being aps-c specific). Ready to pull the trigger I found that they package this lens with Sony’s high end DSLT, for $1750 at my local camera shop. In essence the $1,400 retail body would cost $950 since I was set on the lens. I put my beloved a57 on Craigslist. Enter the Sony a77.
On the surface I thought this would be a clear cut upgrade and there would be no remorse changing cameras. I get 24.3 megapixels over 16.1 (I know I said it didn’t matter but the option to do huge prints is nice), a three-hinged articulating screen over the a57’s troublesome two, oled vs lcd viewfinder, better colors and a weather-sealed magnesium allow body over the plastic one I got used to. I didn’t realize I was going to lose a few things along the way. First I lost light sensitivity. The megapixel crammed a77’s sensor doesn’t fare as well as the a57 in low-light high ISO situations and cannot go above 1600 in video mode. The a57 can do 3200, not great mind you but better than no video. The a57 has a focus magnifier in the digital zoom function that can aid manual focusing in video mode. The a77 does not, but they both have peaking (where focused areas are highlighted in red, white or yellow). It’s also substantially heavier, though good for durability, making long handheld shots a workout. Overall, I still consider the a77 a huge upgrade. Moving on.
I started to unknowingly pixel peep the videos that streamed to me from Vimeo. I compared them to the raw footage from my new a77 and wondered why I wasn’t seeing the same quality. I was semi-obsessed with how the Canon 7d (most relative price and build quality-wise to the Sony) had such clear images let alone the $500-700 range Rebel t2i, t3i, & t4i line. Let’s not get started on the hacked Panasonic GH2 which produces a $10k sharp image. I know you can take an iPhone and produce some excellent video. It’s up to the framing and story telling to make motion pictures captivating but I needed to know why my highly rated a77 wasn’t delivering the goods. I dug a little deeper.
It’s in the codec. Sony created the AVCHD standard tp avoid paying h.264 royalties to Apple. While the 2.0 version is highly efficient, the 4:2:0 and 24 mbps bitrate (4:2:2 in the Canons and upto 170mbps in a hacked GH2) doesn’t hold up well to color grading. Things can fall apart if pushed too far. The codec also macro blocks (creates large blocky screen artifacts) in blues and exposed blacks. Video is softer than the Canons and retains less detail than the GH2 as a result of downsampling that monstrous 24.3 megapixel sensor to 2mp (or 1080p). I started to get depressed at my investment.
Then I realized something about all the videos I was watching. Canon’s DSLRs have been out for about 3 years and Panasonic had the hack on the GH1 which came out two years ago. Professionals have been using these cameras. That means they had the right setup, knowhow and equipment (lighting is huge). The launch of the Sony a77 in August 2011 was hugely affected by the floods in Thailand and they didn’t become readily available until early this year. So all the videos out there were enthusiast-level but hardly professional studio filming. Upon further investigation, searching for raw video test footage from amateurs on the Canon Rebels-T3i yielded the same quality footage I was seeing out of my a77. I was a Sony enthusiast once more. This was a challenge.
Thanks to the Alpha SLT shooters across Vimeo and the people over at EOSHD I learned a few things. One was to shoot in Sunset mode with manual white balance (important otherwise the reds will be pushed). Sunset mode creates smoother gradients and exhibits less artifacts. TURN DRO OFF. Sony’s dynamic range optimizer is on by default and though it brings up shadows, it’s artifact happy. Try and get the picture the way you want it in camera and don’t rely on heavy fixes in post. I like to keep sharpness at 0 with whatever picture profile I shoot. -3 is the standard but the a77 is softer than the Canon’s and +3 yielded choppy aliasing. (after further testing I’d suggest -3 sharpness). If you’re shooting in auto set the max ISO to 800. If you’re shooting in 1080 60p and want to use autofocus, point to different lighting sources and toggle the ael button on when you 1/125 shutter speed. Rule of the thumb is to double the frame rate. So a 24p rate should have a 1/48 shutter speed. On a DSLR/SLT 1/50 and 1/125 are the closest you can get for 24p/60p respectively for the most eye-friendly motion. Combat low light with fast glass not higher ISO but you knew that. I use an old photoshop trick to get cleaner images by overlaying a copy of the video and setting opacity to 50% with a slight Gaussian blur in Final Cut Pro X. It gets better.
If you’re a Sony shooter and were wondering about the video, be happy. First off, I’m pixel peeping on a Retina Macbook display and all faults are null and void when outputting to a tv or projected. We have a lot things that other cameras don’t currently. In body electronic stabilization for video works great negating the need for expensive IS glass. Cheaper lenses, money saved. Although it crops part of the video image to give it room to stabilize it, you still get aps-c sized depth of field. 60 progressive frames at the full 1080p resolution means super clean slow motion. It’s as easy as dropping the footage in a 24p timeline and conforming the speed. No need for Twixtor, money saved. That translucent mirror that blocks a third of the light, giving us the high ISO problems, enables us to see what we’re filming through the OLED. No need to glue a view finder onto the lcd screen, money saved. The way the lcd screen articulates and focus peaking means you don’t need a separate monitor. Money saved. Now the Audio Gain Control is a nuisance but it does work well and the on board stereo mic is not bad for B or ambient audio. The SSM in the kit lens designates it as fast and silent. The AGC surprisingly doesn’t pick up the sounds this lens makes under normal conditions. I also find that if you yell (it’s silly) into the mic when you first hit record, it pushes the AGC down creating a better floor level. Combine that with the fast Alpha SLT-only phase detect auto focusing and it’s a great run-n-gun/sports event camera. The AVCHD 2.0 codec is efficient and you’ll probably end up spending less in SD cards and hard drives if you record a lot. The GH2 and Canon’s Full Frame Mark iii still provide better video but one requires hacking, the other costs three grand body-only. In the end, composition and framing will do a lot more for video than the tech behind it.
