M.Zukio 75 mm question

[Invicta]

Is this sentence from a review of the M.Zukio 75 mm F1.8 correct?

You will want some sort of lens hood and/or a filter on the front end of the lens since it has no optical coating. (This is one of the very rare times I think a permanent skylight filter of very high quality may be in order.)

From this review.

It sounds a little odd to me not to have any coating on the front lens element.

Can anybody who has one of these lenses confirm either way?

Re: M.Zukio 75 mm question

I have this lens. I bought and used it extensively in the sunshine of Australia before I got a lens-hood for it. And I don't believe in filters. Absolutely no signs of flaring. Definitely the very best lens I own, or have owned.

Another quote from the same review..
"This will be new to some of you, but high-end Micro 4/3 lenses rarely have any optical coating to reduce internal reflections"

Really? Really???

I find it very very hard to believe Olympus make lenses with no coatings. Surely this person is mistaken....


EDIT:

Here's a page with a picture of the lens, with the ususal coloured reflections indicating coating.

I do see they refer to "Olympus ZERO multicoating".. where ZERO stands for Zuiko Extra-Low Reflection Optical rather than None..

I suspect the reviewer needs to review their research method

I think you have solved the problem.

Also maybe Olympus marketing speak needs to use less ambiguous terms.

Yes, the Interweb is full of useful statements of fact - some of which are true. Others are not.

We live near one of the Civil War battlefields in Newbury. I read a web page that states the mounds on the local playing fields are where the dead and their horses were buried after the battle in 1644. Fact.

Duh! They are Neolithic

Re: M.Zukio 75 mm question

The lens actually has a new generation of anti-reflection coating that Olympus now uses.

Re: M.Zukio 75 mm question

From the official Olympus press release:

The ZUIKO Extra-low Reflection Optical (ZERO) coating is twice as effective as conventional coatings, giving you the confidence to shoot in bright light without fear of ghosting and flaring. What’s more, this lens also delivers reliable circular bokeh without the dreaded vignetting or off-axis aberration.

Maybe he thinks 'ZERO' mean no coating! LOL!

LOL, yes I was thinking of buying some shares in UV filter manfacturers in anticipation of the increase in demand.

Re: M.Zukio 75 mm question

I read the review - he goes on about bokeh and his rather unimpressive sample shots don't show bokeh effects at all...

Not being big headed, but here are mine:

Excerpt from my article at: http://fourthirds-user.com/2012/06/f...o_75mm_f18.php



First, taken with the m.Zuiko 75mm f/1.8 @f/1.8



Secondly, taken with the M.Zuiko 45mm f/1.8 @f/1.8. The model is roughly the same size in the frame but the camera is closer than with the 75mm shot. The background covered is wider and so busier, even though it is blurred.

Re: M.Zukio 75 mm question

Given the new coatings people will now need 3 protective filters stacked on the lens to protect them.

And of course another filter to protect the expensive filters!

[David M]

Re: M.Zukio 75 mm question

Not really Stephen, the 2 filters closest to the lens are the expensive ones, the outer filter a cheap one to protect those.

Glad you've clarified that - I was getting worried that we may cheapen the whole set-up.

Re: M.Zukio 75 mm question

Nice to see that comparison Ian. I'm waiting for my 45mm to turn up (from a member on here) and it's good to see the quality of the little brother stacks up to the big one.

As you say, apart from the obvious, unavoidable difference between the 75mm and 45mm backgrounds, I can't see any real difference in quality between the two.
