Sorry one question and probably a daft one (bear with me I am still new to all this DSLR stuff!)

Is it any good at portraits?

Thanks once again oh gurus of the photo world!

There are actually 4 versions of 18-50mm zoom lenses that have been made by Sigma. So, it might help to be more specific.

I've owned 2 of these ; the 18-50mm f2.8 as well as the 18-50mm f3.5-5.6.
The first one is quite a bit faster and sharper lens while the latter is a budget lens and frankly is not as good as the kit lens that comes with the E-420.

The 18-50mm f2.8 is a fine lens with great sharpness and image quality.It makes a great all around zoom and, I think, a good portrait lens. I replaced it with a 12-60mm ZD lens as I wanted the wider angle of view and the longer reach the 12-60 offers.

I don't believe any of the 18-50mm Sigma lenses are manufactured for the 4/3 mount anymore.

Thanks Zig it is the f3.5-5.6 thats listed on eBay, which explains why its cheap at 95.85 for a new lens.

Maybe one to give a miss.

the F2.8 version is supposed to be a cracking lens, so if you can get your mitts on one of those then you cant go wrong. Have you looked out for 14-54MK1 ??

Thanks Zig, I'll have a look at mine when I get in. What is the difference between the MK1 and MK2?

As written on Olympics' official website:

Developed as a successor to the ZUIKO DIGITAL 1454mm F2.83.5 (introduced Oct. 2003), which itself earned high praise from advanced amateur and professional users, the new ZUIKO DIGITAL 1454mm F2.83.5 II boasts High-Speed Imager AF support and a circular aperture mechanism for higher imaging performance. Thanks to its support for High-Speed Imager AF, enabling users to enjoy responsive AF Live View shooting, via the camera's LCD monitor. In addition, the lens supports creative photography with a new circular aperture mechanism, excellent close-up shooting capabilities, and a full complement of other performance features.



It is my understanding that the circular aperture blades provide better out of focus results.

I've not used one, so cannot make any personal observations.
