villagranvicent: Seems like I get into a math MIT forum...

Everybody seems so concern about depth-of-field control, then why bother with FF?? Go get a nice digital medium format back, or even better, a 4x5 or an 8x10 camera and you will see what real DoF control is. And guess what, you can get pretty shallow depth of field with any 1.4 lens in this format if you know how to work around it.

@yabokkie, large format lenses have apertures of f/5.6 f/6.3 ans sometimes f/8.0, yet they give bokeh and dof that practically sets standards for DOF, even at f/8, the bokeh (the look) of a large format beats any other lenses (or format's) look.

when was the last time people complained about the insanely high price of the 200 f/2's from canon and nikon? and by the way, what is full frame? 35mm? if so, then what is medium format? larget format? double frame and quadruple frame?

for the micro four thirds cameras, the 75mm f/1.8 is what olympus has offered as a fast telephoto portrait lens, just like nikon and canon have for their formats, the 135 f/2.0's :)

mark25: dont fry me, but i just checked the prices of 'similiar' lenses on bhphotovideo.com;

Nikon 135 f/2 DC : $ 1289.00

Canon 135 f/2 : $ 1014.00

Sony 135 f/1.8 : $ 1798.00

Voigtlander Heliar 75 f/1.8 : $ 715.00

full frame shooters would obviously go for their 135mm lenses, whereas APS users can benefit from 85mm f/1,8 lenses or the higher-priced 85 f/1,4's :)

for someone who likes to stick to micro four thirds camera system for whatever reasons, it is very promising to see such a lens (with full automation of focus, aperture etc) at a price lower than $ 1000.

i think its about the same size as another 85 f/1.8 lens, so a lens that offers double the focal length in a small size does add a weight benefit at least.

i had a Nikkor 85 f/1,8 for my d7000 which i use on my ep-2 sometimes and it always gives good, interesting results (focal length equiv: 170mm)...

be it lenses or cameras, they are tools for photographers, and should be sought, bought and lusted for accordingly...

Depth of Field: Full Frame, Micro Four Thrids.

i think it is safe to say that medium format (when used with film for coverage of the whole frame) has more depth of field than 35mm. take into account my Mamiya lenses for a second. my 90mm Sekor f/3.8 gives DOF equal to 1.9. my 180mm Sekor f/4.5 gives the DOF of f/2.2, but when i look at the 6x7 photos, they 'look' as though their DOF is richer. obviously, a full frame shooter standing next to me would laugh at how my 180mm f/4.5 (90mm f/2.2) lens is slower than his 85mm f/1.8 or f/1.4 lens, but the only thing i can think of is that for a "90mm like look', the only lens mamiya made for me is the 180mm f/4.5.

i also had a Nikkor 105mm f/2 DC lens, and i now own a Mamiya Sekor 210mm f/4.5 APO lens. i really liked the results of the 105 f/2 Nikkor, but have the same (even better) to say about the Sekor 210mm f/4.5 despite the slowness.

the look of a particular lens of a particular focal length has to do with the format its used with.

johnsaxon: Let me just run right out and buy this lens for $900. Oh wait, I forgot that I'm not one of the group of Serious Amateur Photographers With Unlimited Money.

slow in terms of what? indeed, it is like a 150mm f/3.6 lens, but the light gathering capability is that of a f/1.8 lens. the slowness won't affect exposure, but depth of field, and that too, only slightly.

Ben Raven: The RAW MATERIALS cost of glass, materials, mechanics and electronics is merely the STARTING point.

The MAJOR cost of any high quality optics, photo or otherwise, really starts piling up with:
1. The creation, design, testing and optical engineering of a new lens formula that can achieve top levels in all the areas of optical image performance.

2. The expense of producing each element to the high tolerances and exotic shapes necessary, and precise application of multi layers of advanced anti-reflective coatings

3. Final assembly to, again, extremely high tolerances, alignment, centering and maintaining necessary super quality control.

As we go up and up in quality and performance so, PROPORTIONALLY, do the time and COST of all the above !

NOTE: The format is not a directly proportional factor in these

To think otherwise is like saying a Bugatti Veyron costs $3million just because the delivered metal, carbon fiber,and tires cost so much.

The Moral: You get what you pay for.

no, i would not call it paying more. if u 'need' this lens for its focal length, its aperture and IQ, then you have to. just like those willing to shoot with perspective control, tilt-shift lenses have to pay those hefty prices. the intended use it what justifies the cost.

how about this:

Nikon has announced its pricing for the D4 high-end camera. The price will be $5,999 for the body and $119-$9,999 for the lenses, meaning you can expect it to create around a $10,000 dent in your pocket if you want to be able to take pictures with it.

does this give a good idea of how much you'll need to scrape together....????

it is very sad and strange on dpreview's part to make the price look frightening by using unnecessary 'dent in the pocket' and 'how much you'll need to scrape together' phrases.... and after reading the people's response in the comments section, it looks as if they have lured many prospective buyers away...

as much as i like dpreview, this particular 'style' of price announcement from them is, in my opinion, something to which i strongly object, especially keeping in mind that those are MSRP prices...

:( sad

In reply to:

incidentmeter: Olympus users have long wanted to see Olympus return to their glory days during the 1970's-80's when they innovated and revolutionized cameras. Today Oly is known more for its late entry, copy-catism and poor marketing especially in the US.

I believe the OM-D is Olympus' last and best chance to re-establish itself as a leader. Clearly the timing of this release is excellent since the market is infatuated with retro-looking bodies. Oly's products have always been good but the biggest issue is image quality especially at higher ISO's. I purchased my E-3 because of the in-body image stabilization and to leverage my investment in older Zuiko OM glass. It's an amazing camera but for high ISO, it clearly falls behind Canon and Nikon. If the OM-D can shoot well in low light situations, I think it will be accepted in the market.

My biggest fear is that if this camera is a smash, Oly will "rest on its laurels" like it did on the original OM series. Innovation is the key to success.

i think olympus has done quite a lot of innovation; sensor cleaning, live view, mirrorless, in body I.s. and a swivel screen on an slr were all quite innovative. Their ep2 and were well received by the reviewers.. their glass is superb too. Their evf on the pen cameras too are very good. True olympus is not as big a player as the other two but in its own right, I believe it has been quite consistent with a good line up of products.

andrea_g: I wonder if VF3 iworks with XZ1 too. It would be perfect on that small camera!

it will work perfectly well with xz1. that should make a very nice setup.
