We've just posted a hands-on preview of the Canon EOS 100D/Rebel SL1. Distinguished by its impressively small form factor, the 100D's 18MP CMOS sensor, 3" touchscreen LCD and 1080p30 video resolution will be familiar to followers of the Rebel series.

Has Canon managed to maintain its customary handling experience in the smallest DSLR it has ever made? Click through to read our preview and find out.

We've just posted a hands-on preview of the Canon EOS 700D/Rebel T5i. Remarkably similar to its predecessor, the Canon 700D's new model number seems intended more to showcase the new 18-55mm STM lens than to highlight the new camera's few minor changes. Does the 700D remain a good choice for first-time SLR buyers? Click through to read our hands-on preview.

Canon has announced the EOS 100D/Rebel SL1, the world's smallest, lightest DSLR. It shares the 18MP resolution, DIGIC 5 processor, 3" touchscreen and 1080p30 video capability of the mirrorless EOS M. The camera does introduce much wider scene coverage of Canon's Hybrid AF system and shoots at up to 4 fps. The 100D has a recommended price of $799.99/£799 with the co-announced EF-S 18-55mm f/3.5-5.6 IS STM kit lens.

Canon has moved early to replace last year's 650D/Rebel T4i with the 700D/T5i. Like its predecessor, the new camera has an 18MP APS-C Hybrid CMOS sensor with built-in phase-detection autofocus, a DIGIC 5 processor, a 9-point cross-type AF system, and Full HD movie mode. Among only a few minor changes, the Canon 700D is bundled with a new 18-55mm STM lens, which should offer better movie AF at a recommended price of $899.99/£849.

Nikon has said it will spend around ¥600m (around $6.3m) to establish a factory in Laos. The factory will conduct part of the production process for the company's entry- and mid-level DSLRs, with final assembly still taking part in the existing Ayutthaya plant in Thailand. The move aims to increase production capacity and help reduce costs, the company says. The announcement suggests all mass-market Nikons will still pass through Ayutthaya, where all production was halted for several months following a devastating flood in October 2011.

Beyond that, both are 20x compact superzooms with 25-500mm equivalent image-stabilized lenses and 3 inch 460k dot LCD screens. Both feature 12MP back-lit CMOS sensors and the company's latest Digic 6 processor.

The Japanese RRP of ¥90,000 is the same as that for the existing AT-X Pro DX 12-24mm F4 II lens. (via DCWatch)
