70-300 vs 75-300

[OXO]

Hi All,

There's a considerable price difference in these second hand, but is there really much to recommend the 75-300 over the 70-300?

Did I read somewhere that there is a bigger failure rate with the 70-300?

In my experience the 75-300 is much quicker to focus than the 70-300 and is silent when focusing, unlike the 70-300 which makes an annoying whining sound. That is enough for me to stick with the m4/3 version.

Has anyone seen some good quality comparative images from these two lenses ?

Someone made here a test:

http://www.forum-olympus-france.com/forum/topic/35540-70-300-vs-75-300/

If you do not know french, use google translate.

According to this test from this link, 75-300 is better (sharper) at any focal & aperture than 70-300.
Crops from pictures made with mft 75-300 are in the left side. 70-300 in the right side.
If I look to these pictures, 75-300 performs better in deed.

And it looks like 75-300mm is good enough wide-open at 300mm.
I have 70-300mm and is very soft at F/5.6 and 300mm. I ussually stop down to F/8.0 or in the worst case to F/7.1

The price and macro capabilities are the only advantages of 70-300 in my opinion.
If the price does not matter, I would choose 75-300 mft because is smaller, sharper and has much faster focus.

Re: 70-300 vs 75-300

The 70-300 lens can be damaged in its drive because it rotates the front lens external section (spiral), especially if not careful removing (& replacing) the hood, whereas the M75-300 is internal focussing. I have both but only used the 70-300 lens until I could get the M75-300 lens as it is so much smaller, lighter & quicker focussing. I also modified the 40-150 lens hood to fit it to keep it smaller too.

Also a MMF2 or 3 adapter is needed with the 4/3's 70-300 as well.

Ahhh. < light bulb comes on>

Somehow, i had a senior moment and didn't realise that the 70-300 is 4/3 and the 75-300 is m4/3

That's saved me a lot of grief.

It's 70-300 for me then as I have an E-520. All I need now is another kindly soul who's giving one away

I'm glad that was worked out then. The 70-300 lens will go well with the E-520 & it was that E-520 enthusiasts kit where I got my 70-300 (4/3's) lens.
