Sony SLT-A37 Hands-on Preview

May 2012 | By Richard Butler

Preview based on a pre-production SLT-A37 with firmware v1.01

With its usual alacrity, Sony has managed to release seven SLT models since it first launched the concept in August 2010. In that time, the range has expanded from two models to four and the A37 has a role to play in ensuring the line-up makes sense. Most consumers (understandably) care little about product differentiation but the A37 helps make Sony's lineup more coherent than it's been in a while - making it easier to work out which product is for you.

The A37 replaces the entry-level A35 and uses essentially the same body that it shared with the original A33 and A55. The hand grip has been modified - making the finger grip slightly deeper and more comfortable. Beyond that, Sony has added the second-generation version of Sony's 16MP sensor. It also adds a series of features from recent, higher-end SLT models, such as lens correction, focus peaking and the lag-reducing 'electronic first curtain' option.

These changes mean the four-model SLT range are all based on the same generation of technology, with logical increases in features and capabilities as you move up the range. In order to make the A37 even more distinct, its rear screen has been downgraded, compared to the A35. It gains a tilt up/down mechanism but shrinks down to a low-resolution 2.6" 230k dot panel, rather than the 920k dot, 3" version the A35 shared with the more expensive A57. The benefit to the user is another $100 taken off the MSRP - meaning the A37 is being launched at a price $150 lower than the original A33.

Beyond this, the changes are subtle - the A37 gains the A57's improved viewfinder optics, and it becomes the only SLT not to shoot 60p video - instead offering 60i and 24p as its highest frame rate options, both at 24Mbps. The A35's continuous shooting rates are unchanged, with the camera offering 7 frame-per-second bursts at reduced resolution (8.4MP) in a mainly automated mode.

The A37 gains the A57's 'By Pixel Super Resolution' intelligent interpolation, with the 'Clear Image Zoom' it brings. It also allows the introduction of the 'Auto Portrait Framing' feature that looks for a good portrait crop in images with a face in them and saves an upsized crop alongside your original image.

The other area the A37 is impressive is the degree to which it accommodates video shooters. It features built-in stereo microphones, a wind-cut filter and the ability to autofocus during movie shooting (with phase-detection AF that should minimize over-shoot). There's also a stereo mic input for more committed shooting. And, if you're willing to use manual focus, you gain more manual control over exposure can use the focus peaking contrast highlighting to help with manual focus following.

Sony SLT-A37 specification highlights

  • Revised 16.1MP CMOS sensor
  • ISO 100-16000 (Auto 100-3200)
  • By pixel super resolution intelligent up-scaling
  • Picture Effects processing options
  • 1080p24 / 60i HD movies in AVCHD format
  • Focus peaking manual focus aid
  • Stereo microphones and mic input socket
The A37 uses an very slightly modified version of the original A33 body - making it considerably smaller and lighter than the A57 that sits above it in the mode range.

The arrival of the A37 leaves the Sony SLT lineup looking more coherent than it has in some time, with an obvious separation of features between each model.

The a37 does not overheat. At least mine does not. I owned a a33 and I know what overheating is.

Can someone please advise me on how to place my settings so I can take black and white photos ?

David zzzzzzzzzz

I caution against this camera, have the A35 and am totally underwhelmed by the exposure and color balance. Autofocus is superb and speed is fine, just not happy with white balance.


Can we use external GPS with it?

Fadhil Parewangi

hey, I own this camera too.
well, I was in depth, I bought it 3 days ago.
I felt lucky to get a bonus like "ACC-FW1" and a 50mm f/1.8 SAM.
so far I think this camera is pretty good, and and instead chose A57, I can save $ 200 for an extra lens. Great Save!

Got this thin from one of the store in Banglore(India), this has amazing features and much better performance than nikon D3200, canon 600D....Tried all of them live....most important is print quality....its amazing....!!!!go for it.....

Francis Sawyer

The camera has a printer built in?


dpreview wont review this camera till 2013.... we are still waiting for the a57 review which was released in march.......sighhh


I'm with you Swede. I ordered the first day Sony had it available on their site and I received it yesterday. All I can say is wow! It totally exceeds my expectations. I use the LCD screen for high or low shots and it's resolution is just fine. It's actually a better match to the original 3:2 aspect ratio. Today I shot with my Minolta 100 f2.8 macro and the results were stellar. The handgrip fits me like a glove and all of the controls are easy to access. I formally owned an A100 and so this is a big step up. Smaller is better!

Does the A37 really not support the RMT-DSLR1 infrared remote control? As I see in the specifications that one of the Drive modes supports the RMT-DSLR1. Also, there is a visible infrared window on the grip, below the shutter.

However, it may be possible for Sony to leave it out as they did with the NEX-3/C3/F3.

It does support that remote...I bought it...

It DOES NOT support that remote!!!! I bought the camera, and The Sony Store sold me that remote, and it DOES NOT work. Sony tech support verified this for me. It only supports the wired remote, which has a 5m long cord. NOT HAPPY!

But does it have overheating problems??
I had to sell my A33 because it would overheat after about 30 minutes of being continuously on - not even video, just stills.
No good when you are shooting a concert or performance for business.
If that's fixed, I would reconsider an SLT - very good camera except for that deal killer.


Why were you using their entry-level camera for "business" in the first place? It was probably never designed to be used that way, and thus the overheating problem.


"never designed to be used that way, and thus the overheating problem".What doest that statement mean? Taking pictures? I also own a A33, while it has many good features, The overheating is a definate drawback, especiality in video mode.
It also has a problem bringing up the image after a wait while shooting, have to turn off and on to get the image back in the viewfinder or live view, causing many problems. Have always been a Nikon user and I guess I have to return to Nikon.

it should not overheat within 30mins of shooting pictures. even at entry level overheating is a troublesome, even when not used in business and concerts...why o why...

I think the overheating problem was fixed with the A-35, my A-35 does not overheat, I have used it to shoot concerts and weddings.

kushal raj patnaik

hell! this model is so close to the sony slt a57!! gosh!
i was going to buy the a57, but here comes a37 which has again confused me to which model ii should buy!

evn the cost difference is a 100 bucks and the difference between their features is not worth the price change!

really!! sony, the a57 was a drastic change...but, yet another model!


IMHO, A57 is SIGNIFICANTLY better camera. The diff is well-worth $200 if you ever going to shoot sports, for example.


In what ways?

what is wrong with DPR cant you put the resolution of the Vf ? same as the g3 no figures. also would be nice if you could tell us weather the hdmi is playback only ? or live view !


Richard Butler

The database didn't have a category for viewfinder resolution. One has now been added. I shall look forward to populating it.


Very disappointing. I was looking for an A55 replacement with focus peaking and electronic first curtain shutter but still in the awesome small sized body since A57 got much bigger vs A55. Too many downgrades here to consider it, though.


Is it just me or do the sample images of auto portrait framing look washed out? Is this the best that could be produced for the preview?


Sony, just how many bodies do we need?


The A390' which I own has the same 230k res LCD as the just-announced A36 is 2.7" compared to 2.6" on A37, not too much of a difference and tilts just like the A33 and last entry-level OVF Alpha, my A390.

The grip design is A33 or A390 like, a nice change-with a small black strip part (a bit like my A390's grip-though that one accepts a RM-DSLR1 remote so the black strip for remote sensor is a larger).

The screen aspect ratios are wrong for the A65 and A77 (and presumably A57). The A33/55/35 all had 16:9 screens, the newer SLTs are 4:3.

Richard Butler

You're absolutely right - I should have checked, rather than trusting the spec list I was given.

kushal raj patnaik

for a57 it is 4:3

still incorrect figures for the screens. Come on Richard, takes a minute.
But thanks for the fast and nice previews! That's great!

I like the A57 better :-)

Rooru S

Sigh...7fps but with cropped picture? What the heck?! A33 and A35 were better. 2.6" screen? A33 and A35 were better, Although some will appreciate the tilting screen (although it tilts only, not swing)

Sony..you can do better.

Aleo Veuliah

It seems a good camera, the Sony sensors are good they have to make more lenses


...and again, they did not change the crippled AE bracketing. I bought an A55 hoping they will fix such a stupid thing in firmware, but no... so if you like HDR, stay away.


Doesn't A55 have built in HDR function?


Yes, it does.


Finally, the Tilt LCD of A33 makes a comeback in the entry level model, the LCD Size & Resolution reduces though. Have been using the A57 for quite a while now and the low light High ISO JPEGs are mind boggling! They seem to outperform almost everything from Canon & Nikon, barring the Full Frames.

The icing on the cake is the SAM 18-135 bundle (across the range), making for a versatile kit at at amazing price. The (exceptional) EXMOR sensor finally gets a better lens to show its true colours (pun intended), as the 18-55 quality wasn't upto the sensor's potential.

Haven't been this surprised since i saw the Olympus OMD-E5 samples. The features set seems exactly the same as the (amazing) A57, which is a good thing. This one looks like a segment beater to me.


wait what?


What 18-135? I've heard rumors but nothing concrete.

Richard Butler



Great overview.


What a downgrade from the 33 and 35 models...Come on Sony!


In the intro page's comparison, you list , "Continuous shooting rate (no AF)" That's not true. A77/A65/A57 all do continuous AF in 12//10/12 fps mode.

Sorry, I mis-described speed priority mode in the table. It's now been fixed. We're still waiting for clarification on the number of effective dots in the viewfinder - the specs on our page are consistent with the latest information provided by Sony.

Richard Lewis Ireland

Any idea when the full review is going to be done on the sony a57 and this camera the a37 ?


The finder is 1.44M dots on the Japanese Sony website spec sheet.

Richard Butler

We've seen a series of different specs from Sony on this. We're waiting for clarification.

Bernie M

I was looking for the article to help me decide between a Sony A65 and a Nikon D5100. I will also include an additional prime and tele lens.
