View Full Version : What Lens

29th August 2010, 08:18 PM
I'm hoping to tap into the knowlege and experiance that I see all the time here on this forum. As I said in my intro I'll have lots of questions and the answer was ask away so here's the first. At the moment my biggest interest is in closeup picture's of flowers and insects the setup I'm using is e-520 with mainly the 14-42mm with a sigma achromatic +2 attached, I'm looking at buying a new lens and thinking of either olympus 70-300mm or sigma 105mm, I've seen the sigma results in postings and I really like what I've seen and it is a 1:1 macro. I've also seen in postings that the 70-300mm can be used for closeup work. Any advise in choosing a lens will be very much appreciated I'll put a few pictures in my gallery for you to look at.

I dont know the sigma but I have just got a 50mm F2 that is an amazing lens for close up and anything else.. 70-300 is a bigger but capable lens and gives you the added long zoom but it is not a macro

The two lenses are in a different class. The Sigma 105 is an excellent macro lens - I'm selling mine as I now have the 150 - whereas the 70-300 is a long telezoom. It depends entirely on what you want to photograph. In the long term you'll probably want both.

Hi Bob

David gives you an excellent response regarding the Sigma 105mm and the Oly 70-300mm.

I don't own the Sigma, but I do have the Oly 70-300 and can vouch that is is by far, the best Oly lens for capability/price. Sure, the other long Olympus zooms are a class above again, but yo pay for that too!!

The 70-300mm is not a macro lens, it simply has a switch on the side that alternates between auto focus (the camera does it for you) and manual focus (regardless of the camera setting it only manually focuses). The manual focus mode allows you to focus physically closer to your subject than it allows when in auto focus mode - that's all. This isn't a macro setting, just a closer focus ability when in manual.

I am not sure how it compares to the Sigma 105mm, but another lens you could consider is the Olympus 35mm macro. This is a 1:1 macro and I've found it to be a lens capable of excellent results. You would benefit from the reach of the 105mm over the 35mm though, but the 35mm isn't that expensive.

Why not talk to Dave about his 105mm?

Hi Thanks all for the advise it's made me think in a different way what use a new lens will get.

Chris I hadn't thought of the 50mm but It's a lens to seriously think about.
David yes I probably will want both but which first, your sigma is well worth thinking about as I've not thought about buying a used lens before which leeds to John bringing up the 35mm which I 'm sure would be good for my flower pictures so thank you all for making me thing more about what to get first. Here's a few pics taken with 14-42mm with sigma achromatic fitted.
