If you're a keen photographer looking to upgrade your compact to something more substantial, there are some excellent pieces of hardware on the market right now. We've reviewed various cameras throughout the year, but bargain hunting is part of the process too, so we thought we'd take a look for some of the best discounts we can find.

With Christmas just around the corner (and a fresh batch of model upgrades on the way), it's possible to get some good quality cameras at surprising prices.

Here are a few deals that have recently caught our eye...

Canon EOS-1D Mark IV

This is Canon's professional-level DSLR, which means it's not for the faint hearted. It features dual DIGIC 4+ processors alongside a full frame 16.1 megapixel CMOS sensor. Other highlights include an expandable ISO rating up to 102,400 and Full HD (1080p) video recording. 

Originally retailing for an eye-watering $6,400, you can now get the Canon EOS-1D Mark IV for around $4,400.

Panasonic Lumix DMC-G10

Okay, so the Panasonic Lumix DMC-G10 is actually a Micro Four Thirds camera, but it's still a cut above your average compact camera. Highlights include a 12.1-megapixel Live MOS sensor, It also comes with an electronic viewfinder (EVF) to supplement the 3in LCD screen. (Read our review of the Lumix DMC-G10.)

The Panasonic Lumix DMC-G10 has a price tag of $899 - or $499, if you head to Ted's Cameras.

Sony Alpha SLT-A35

The Sony Alpha SLT-A35 is a mid-range DSLR optimised for action shots and fast moving subjects. It boasts a 16.2MP Exmor APS HD CMOS sensor, Full HD video recording and a Continuous Auto-Focus mode for shooting on the go.

The Sony Alpha SLT-A35 currently has an RRP of around $700, but we've seen it for as low as $500. 

Nikon 1 V1

Another Micro Four Thirds-style offering, the Nikon 1 Series V1 is the first compact system camera from Nikon. It comes with a 10.1-megapixel sensor, and electronic viewfinder and is capable of taking some surprisingly sharp and vibrant pictures (read the full review here).

Ricoh GXR

The Ricoh GXR is an innovative MLIC characterised by its eccentric lens system. The GXR body itself contains no image sensor; only the LCD monitor and associated electronics, battery and SD card slot. Each lens unit is a self-contained, sealed box incorporating not only a lens, but also the iris mechanism, shutter and image sensor - essentially, a complete camera.

Originally retailing for over $1000, you can now pick up the GFX body for around $380. 

Canon EOS 600D

The Canon EOS 600D is a solid DSLR/video camera hybrid complete with a 3in camcorder-style flip-out screen.  It boasts an 18-megapixel APS-C CMOS sensor, nine-point autofocus and 63-zone metering system and a 3.7fps maximum burst speed for up to 34 JPEG frames or six RAW frames.

When it was released, the Canon EOS 600D cost well over $1000. We're recently seen it for as little as $535. 

Olympus E-450

The Oplymus E-450 might be getting a bit long in the tooth, but it's still an accomplished DSLR.  It comes with a 10-megapixel sensor, a TruePic III+ processor and a snappy continuous mode (nine frames in 2.3 seconds). You can read our original review here.
