Which Compact Interchangeable-Lens Camera?

These are exciting times for DSLR enthusiasts. We’ve all marvelled at the creative and operational flexibility afforded by the large dial, switch and button infested DSLR bodies and interchangeable purpose-built lenses. We’ve been spoiled for the impeccable image quality afforded by the 8.5-15x larger APS-C sensors (upto 34x larger if you’re a 35mm shooter). It’s impossible to look back at compacts. Or is it?

Most DSLR shooters sooner or later realise that their beloved hunk can’t be their only camera. They can’t carry it all the time to family events. They can’t do anything about it if they happened to dine in a fancy restaurant on impulse. Carrying a DSLR has to be planned ahead, owing to its bulk. In the last couple of years, though, the B-level interchangeable lens system manufacturers (anyone other than Canon and Sony) had been pushing the boundaries of how small an interchangeable-lens system could be made. While I’ve followed this category (dubbed EVIL — Electronic Viewfinder, Interchangeable Lens), it’s right about now that I have finally settled on a system. It’s going to be none but the Sony α NEX-5 for me. If you follow me on twitter, you’d already know about this. Here’s a brief overview of stuff that I considered and what sold me on NEX-5.

Luxury Compacts

These are essentially non-interchangeable zoom compacts with puny sensors. Canon G10, G11 and the latest, G12, are leaders in this category, owing to their small size and controls that are suited to DSLR users. Heck, they have an ISO selection dial! Some people also choose the smaller Canon S90/S95 systems. Their undoing, however, is their image quality. While they’re considerably good in terms of IQ, sensor technology has been favouring large and small sensors equally and large sensor systems have leaped further ahead in terms of dynamic range and low-light capabilities. Nikon’s recent offering, the P7000, is a worthy addition to this lineup. It trumps the G12 in terms of specifications though deeper IQ analysis is pending.

Certainly, though, these systems aren’t going to offer the kind of IQ one gets from today’s DSLRs. Written off.

m4/3 EVILs

While Canon and Nikon were busy fighting it out in the 24mm and 35mm DSLR arena, a bunch of B-segment makers got together to create a new shared sensor format and lens-mount called Four-Thirds. This system boasts a 4:3 sensor (compared to 3:2 for 24 or 35mm ones) that has about 1/4 the area of a 35mm sensor. Much better than tiny compacts (4-9x larger) but still not up to the level of 24mm sensors. Early on, these systems focused more on the almost-similar IQ to larger DSLRs with a wide selection of lenses thanks to the shared lens-mount between manufacturers. Models like the Panasonic

Panasonic Lumix GF-1 and Olympus PEN EP-1, however, put the same sensor in rangefinder/EV bodies that were significantly smaller. What’s remarkable about them is that they are about the same size as the Luxury Compacts if you put a pancake prime lens on them. Yet, they offer visibly better IQ and flexibility to change lenses. GF-1 and EP-1 were instant hits with shooters of even Nikon and Canon DSLRs as they afforded DSLR-like IQ and operations, without the bulk. Around this time, people started speculating about Nikon and Canon jumping into the Mirrorless Interchangeable Lens (MIL) segment as well.

I was waiting for a GF-1 update, that fixed some of the auto-focus speed issues and various other shortcomings. That update is yet to come but something else happened along the way…

Enter Sony α NEX-5

This May, Sony announced two APS-C MIL cameras — α NEX-5 and α NEX-3. For the purpose of this post, I’m going to ignore NEX-3, which is just a cheaper version of NEX-5 designed to win price wars where needed.

What’s cool about NEX-5? Well, consider that despite being an all-metal body, it’s considerably lighter than anything in this category. Not only that, it’s also the smallest. It’s smaller and lighter than the Canon G10/11/12, it’s smaller and lighter than Nikon P7000, it’s smaller and lighter than Lumix GF-1, than PEN EP-1 or EP-2… heck, it’s smaller and lighter than anything at all!

In terms of IQ, this sensor beats all contemporary m4/3 offerings hands-down, blows the fixed lens, tiny-sensor compacts out of reckoning and stands all the way up to Nikon D5000’s image quality. Other notable and interesting features are:

  • Tilt-up/-down LCD screen with best-in-class display.
  • Hand-held HDR creation with upto 6-stop difference among bracketed shots. It works.
  • Multiple-shot High ISO blending for reduced noise low-light photography of still subjects.
  • 3-function programmable jog dial and 1-function programmable lower soft-button (firmware v3).
  • High-resolution 2D/3D sweep panoramas. It’s not magical, but it does usually work. A pan-head tripod like the Sony VCT R640 that I have will be of tremendous help.
  • 1080p/24 fps videos with continuous AF (Nikon D3100 is the first to offer continuous video-AF in DSLR form-factor).

No wonder then, that the Sony α NEX-5 is the best mirrorless camera available. In the absence of any significant moves from Canon or Nikon and Sony’s continued ground-breaking advancement into compact APS-C bodies, NEX-5 is also likely to hold its position this year.
