Both of Sigma's new products have been slimmed down and redesigned to perform best with full-frame high resolution cameras

The Sigma 50mm f/1.4 DG HSM (above) is the latest product in Sigma’s “Art” line that was originally announced in 2012.

Comprising 13 elements in 8 groups, the complex optical design has been tailored with Special Low Dispersion and aspherical glass elements to minimise a multitude of optical aberrations such as sagittal coma flare (concentric flare), axial chromatic aberration, flare and ghosting.

The Hyper Sonic Motor ensures fast AF, and Sigma claims to have optimised the AF algorithm. The 50mm has a minimum focusing distance of 40cm.

The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM is a revision of a lens released in 2011. Designed for APS-C format SLRs, the 18-200mm has been reduced in diameter by 4.6mm and forms part of Sigma’s “Contemporary” range.

Designed to be useful for close-up work, the 18-200mm has a minimum focal distance of 39cm and Optical Image Stabilisation (though the latter function is not incorporated in the Sony and Pentax versions).

Both the 50mm and the 18-200mm are compatible with Sigma’s USB dock (for updating firmware) and Sigma’s mount conversion service.

The 50mm will be available for Canon, Nikon, Sigma and Sony mounts, the 18-200mm for Canon, Nikon, Pentax, Sigma and Sony. Pricing and availability are yet to be announced.

    I have had this camera for nearly a year, at first i had a few niggles with it , but over time tweaking a few settings and adding a couple of pro lenes its just awsome, dont take any notice of forums stating the e620 is noisy , its not that bad at all i can get real decent images at 1600 iso with no pp, i shoot jpeg and im well happy with the results just check my flickr shots.

    I have had the E620 for a year now and think it is a good value-for-money buy. It’s poorest feature by a long way is it’s user manual. It is a most irritating document with its too-small-to read icons, its use of nemonics which need (but don’t have)a glossary and over-used cross referencing to other pages in the document drive me mad. Surely a reasonable entry level camera of this quality deserves a decently prepared manual.

    All modern digital cameras take good pictures. The E-620 is exceptional for image quality.
    Many cameras that only get average marks for image quality is usually down to an average performance kit lens. With the Olympus kit lens 14-45, the image quality is probably the best on the market for the price. Put their pro 14 -55 F-2.8 on the 620 and its up there with the very best no matter what price.

    It’s worth hunting around for the E620 two lens kit as there are some amazing bargains out there. The quality of this little camera is excellent.

    Completely useless review

    I bought the e-620 with a dual lens kit at just over the £600 mark from Jacobs. I am amazed by the quality of the results and just love this little camera. I used to use Olympus 35mm kit and this is just as good. Perhaps the pro users with Nikons and Canons will sneer, I prefer Olympus and they have delivered a great camera.

  • David Curtis

    I have just bought an E620, paired with an Olympus 12 – 60 lens.
    Straight out of the box, I was amazed by the results. Once I have got through the instruction book I am sure I will be even more pleased.
    Say what you like but this is one amazing camera.
