Default E-520 and 70-300 Macro

I did not think my E-520 with a 70-300 lense could do Macros.
I saw a few nice ones posted here.
At first I Assumed the 70-300 was only good for Distant shots
and you had to swap lenses for Macros and Distant shots .

Fred, the 70-300mm is a very capable macro lens, if you switch it to manual focus it can focus even closer (more magnification). the auto focus does not bring out the best macro capabilities of the lens. when I went to the Olympus dslr class back in feb. one of the slides listed the 35mm/3.5, 50mm/f2, & the 70-300mm/f4-5.6 as their macro lenses so I think they intentionally designed this capability somewhat, instead of just being a byproduct of shear magnification. try it in manual focus I'm sure you'll be impressed how much more magnification you can get.

Well, I'll be... I had no idea! Thanks for this, Charles!

Beautiful shot, Fred. I'm off to try mine out.

My first attempt with the 70-300mm in manual focus for a macro. Don't mean to hijack your thread, Fred.

Gary & Fred the closest the 70-300mm can focus in auto focus is 47.2 inches. in manual focus the closest distance is 37.7 inches. you gain almost 10 inches & true 1:1 magnification (with 2x crop factor same as 50mm/f2) in manual focus.

I got some nice results with the 70-300 as a macro. Just never thought of manual focus....dumb really. Especially when it'll drive you crazy trying to lock on at times.

All excellent pics.

True 1:1 for film but not for the Oly sized sensor right? IIRC the 50/f2 is sold as a 1:2 lens. I find it all confusing since what I call 1:1 is a view that is the same width as the sensor but some call 1:1 a view that is the same as the width of 35mm film.

John, as far as being technical, macro by definition means life size, anything larger than life size technically by definition is micro photography. the 70-300mm off camera has .50x life size (physics of lens), the 50mm has .52x life size, the 35mm has 1.0x life size. On an Olympus camera these result in the following 70-300mm 1.0x, 50mm 1.04x, & 35mm 2.0x (technically micro photography as stated above.) Olympus sensors are roughly .68 inch wide by .512 inch high which means you could fill the frame with a .68x.512 inch subject at 1.0x. At 2.0x you could fill the frame with a .34x.256 inch subject.
I hope this answers your question.

Thanks for the tip Charles.
I tried a Manual Mode macro.
Turned out Nice.

Fred..

Not that I want to start an argument or anything but I have always understood the term macro to encompass 1-20X and anything over 20x to be micro. Then again according to a book from the 70's the proper term is photomacrography, as if anyone would ever use it! Anyway, the reality is that I can do a 6x shot on my E-1 or 500 and have the depth of field for that power yet produce an image twice the size I would on film. One of the reasons I won't stop shooting Oly. BTW, I find it much easier to use mm when refering to sensor size, makes it a snap to figure magnification, I just shoot a metric ruler.
