sharp lens is sharp

on an aging EP-2

sharp as it is, I still think that the 35-100/2 SHG @ 75 is better at f2...but just to get this in persepective: it's like saying "this Hanzo Katana is better than that other Hanzo Katana"

Have you any side by side images showing "sharpness" and bokeh of these two lenses? Or. is there something else with the zoom you find "better"?

The review done by SLR Gear states, "The Olympus 75 mm f/1.8 M.Zuiko looks and feels like a premium offering, with an old school aesthetic and an all-metal construction".

Photozone states, "looks like high quality metal but is actually made of plastic parts based on a metal mount".

The SLRG review seems to imply that the lens is all metal construction.

I think Cicala at Lensrentals took a copy apart and discussed the build quality more in detail.

Glenn - where are you seeing the 75/1.8 review on Photozone? I don't see that they've reviewed it?...

In any case, the entire exterior of the 75/1.8 is metal.

I did a few comparison shots today...indoors because it's way too windy outside today.

click on the link for the original size

Shot RAW and exported from Lightroom 4 to Photoshop CS 5 without any adjustments whatsoever except for conversion to sRGB colorspace and exported as JPEG Quality 10. All shot manual focus with Live View, close to center as much as possible.

Shot indoors, available light. shot from a tripod, 2sec timer, Daylight WB, Manual exposure. EP-2

Will try to do more when I get my EPM-2 this week.

Yes, it's metal, but IMO it "feels" cheap...especially when compared with the older SHG FT lenses. maybe it's the champagne color. regardles...I would pay a premium for Olympus to get the SHG quality to their current top-end primes and zooms...and not just painting it black like they did on the 12mm..

Just looking at those pictures, I can't tell any difference at all between the SHG zoom and the 75/1.8. What differences do you see on your end?

that was the whole point exactly: cannot see the difference! which goes to show how damn good the SHG zoom is at wide open. color fringing is a bit more controlled on the zoom, but it's splitting hairs, really.

that said, I'm using an aging EP1 (Panasonic) generation sensor. this may change with a slightly higher-resolution, newer-generation OMD (Sony) sensor. we'll see this week when I receive my EPM-2.

I am going to publicly apologize - I mixed up the PZ review of the 45 mm f/1.8 with the 75 mm f/1.8.

Previous posters were absolutely correct (as was SLR Gear) - the 75 mm is of metal construction.

And looking/comparing the images posted by Dale, I'd be hard pressed to choose one lens over the other. Looking forward to seeing PZ's review of the 75.

Is it a surprize- that Dexters $2500 Olympus zoom would beat a $899 75MM M4/3s prime ?

Is there a 35-100mm f2 lens? I want one.

Yes, yes there is. And it's excellent: http://www.bhphotovideo.com/c/product/404517-REG/Olympus_261012_35_100mm_f_2_0_ED_Zuiko.html

Wow ... this could be a very sweet lens for the E5/E-M5 hybrid body. However, the size and weight of this lens is a complete turn-off for me. It's even bigger and heavier than the Canon 70-200L II. So, no thanks! I will stick with my 45 and 75 primes, and possibly add the Panny 150 prime when it hits the market.

Is it just me or is the 75mm an expensive lens? I guess coming from the Nikon camp I am expecting m43 lenses to be much cheaper

If you're expecting pro grade m43 gear to be priced like Nikon consumer gear, then I suppose you'd think it's expensive. Considering its on par optically with pro grade 135mm f/2 lenses, I think it's reasonably priced.

it's heavy. i mean, really heavy (especially with my girly frame) and I've owned a Nikon 70-200 VR1 and this lens is considerably heavy. good thing i didn't get rid of my 3-series Gitzo tripod when i switched to mirrorless.

once you see and hold one will feel the quality from the get-go. If you have the older-design Nikon AF lenses (the crinkle finish) like the 135DC...it's like that except it's much better...even the hood itself is a masterpiece. it's kind of on par with the Zeiss DSLR lenses but the Zeiss lenses has an all-metal design that it's hard to really compare them.

also, this is the ONLY lens i've used that's very good wide open (f2.0) at nearly the entire zoom range veiling and fringing is well-controlled. the ones I've used (Nikons/Canons) are good...but pales in comparison with the Olympus at f2.0. as you can see it goes toe-to-toe with the 75 prime...

I bought this at a really good price banking on the new Olympus hybrid mount. but i'm using it today on an EP2 and EPL1 with good results, so I'm planning to keep it for a long time.

Note that one reason why the 35-100/2 is so good wide open is because you are actually shooting it a stop down. The 35-100/2 optically is a 70-200/2.8 optical design with a 0.5x telecompressor integrated, producing a lens which is optically a 35-100/1.4 (the same goes for the 14-35/2). This can be confirmed by mounting the lens on a dumb adapter (or inserting it without locking so it doesn't sync electronically), you will find that without powering up it will meter about 2/3rds of a stop faster than it will powered up, as the lens actually stops down to f2 when powered up.

The origins of the base optical design are likely Sigma (along with the 70-300 and 14-35) but it's clear that the results are only somewhat related to Sigma's 70-200/2.8, Olympus worked the design over very significantly in addition to the inclusion of the telecompressor.

Thank you dalegaspi.
I went to flickr and downloaded the original sized images. To my eyes the prime was sharper (the third example, in image 1 and 2 the difference is hard to see) but also showing more LoCA. All in all the differences are smaller than I expected though. I get your point.
I used to have the 14-35/2.0 SHG zoom (in 2009, used it together with my Panasonic G1) and while impressive it didn't beat the 4/3 version of the Panasonic Summilux 25/1.4 at 25mm. The longer zoom is indeed impressive (it is also big, heavy and expensive) and you need a grip to make good use of it.

regards,

Jonas
