Sweet just orderd one. Thanks admin.
Nice Snag!!!
booo sold out.
the advantage of this lens against the 45mm/1.8: it gives more bokhe because of the longer zoom.
QUESTION:
so the 14-150mm has than the same bokeh with 75mm/4.2 like the 45mm/1.8???
could somebody replay? thanks already.
The rule of thumb is that doubling the focal length is like having 4 stops (or squared value) larger aperture. You can check it at:
http://www.dofmaster.com/dofjs.html
Here is my graph representing this, and an example formula.

I will run the numbers if I get a chance. 🙂
Oops… not “squared value” but multiplied by 4. I don’t have my math brain today…
I’m getting that 45/1.8 has the same DOF as 75/5.3. Could someone else check my math?
log(75/45)/log(2)*4*1.8=5.306
Of course, depth of field is not all there is to bokeh. It has to do with how an out of focus image is rendered. Some lenses create round, even circles (“good bokeh”), and some create misshaped, uneven circles (“bad bokeh”). CCTV lenses and catadioptric teles, for instance, can have very shallow DOF, but have background that is patterned and intrusive, rather than creamy flat; I actually rather like the look, but it’s still considered “bad bokeh”, by convention rather than because it is actually bad. Lenstip often has test shots showing bokeh, if you want to check them out.
if this is true – I could safe one lens… great, thanks! 🙂
the only thing that is nessesary is than a bit more distance
THANKS J SHIN
J Shin, you made my day !!! 🙂
So it is true 45mm/1.8 has the same Bokeh like 90mm/4.6.
Conclusion: For Bokeh freaks they should buy the 75mm/1.8.
But for those one who have the 14-150mm they don’t really need the
45mm/1.8- > just go to the distance of the 75mm/1.8.
The only thing is the distance to a client is probably better if the photographer is not to far away for a portrait.
I think Olympus had knew why they just bring out the fast lenses now. Also a marketing issiue!?
The bokeh is dependent of the whole lensconstruction and glass (im)perfections, and differs from brand or type.This is more extreme with fast type lenses.
Alexander…your question is not clear and terminology is very Important for any understanding in a technical discussion. i.e. the 75mm has a longer focal length than the 45mm. Not more zoom. It is not a zoom lens.
The are three “major” factors that effect the out of focus area (bokeh).
1. The focal length of the lens
2. The f/stop of the lens
3. The lense’s relative distance from the subject.
Since a zoom has varying focal lengths and possibly varying f/stops it is a very complicated discussion to get a grasp on its Depth-of-Field/Bokeh across its entire focal range.
To simplify things..to get the best bokeh (lowest depth of field) you are “generally” better off purchasing a prime with the largest aperture you can buy…such as the new voigtlander 42.5mm f/.95……but most zooms are a bad place to start for creamy bokeh as most of the best zooms have an f/stop of 2.8 which is a far cry from say a lens with f/1.2. Less expensive zoom with smaller apertures are not a good place to look for good bokeh.
There are many article on the web about these subjects with visual examples and I suggest that you search out “depth of field” as well as bokeh for thorough understanding
One thing that I did not mention are the subtle things that effect the quality of bokeh.
Let’s say you have two different manufacturers that both make a 75mm f/1.8 lens. If one manufacturer uses more aperture blades shaped to create a very “round” aperture whole it will greatly effect the quality of bokeh compared to a lens with few aperture blades that are not curved which create a very “not “round aperture hole.
Also the lens design (number of elements) and quality of glass can also effect the quality of the lenses bokeh.
It’s pretty complicated!!! LOL!
Thanks to all I have to read it tomorrow again…
I just meant that the zoom lens 14-150 hat the same bokeh at 75mm focal length like the 45mm/1.8.
maybe somone can check that. 🙂
Here are some samples I found. Zoom lenses tend to have sub-par bokeh, but these look pretty good. They are from a variety of focal lengths, some in the mid-range close to 75mm.

Phred,
Dont forget the size of the sensor. This is also very important for dof and therefore the bokeh. The bigger the sensor the more easy it is to get nice bokeh.
+1
bokeh is a more subjective aspect and is less dependent from sensor size, its not the same as dof.
I just saw that 75mm on ebay and only 1 left.
They also had three Oly 60mm f2.8 macros and I picked one up for $399. Good deal?
I just bought an OMD EM-5 base on some comment feedbacks by “TheRealStig”. He had a red/blue bullseye icon but haven’t seen him posted in awhile.
I picked up random parts (off of craigslist) like the OM-D EM-5, Leica 25mm f1.4, 14mm f2.5, and now the 60mm f2.8 macro for a total of $1,400. Much much cheaper than my Sony gears and much much better (even better than the a99 with Zeiss 24-70). I still have $2,600 left over from selling all my Sony gear. I think I am done with buying camera/lenses once I find an used 75-300mm.
There isn’t a camera that is as good as the OMD to me (not a PRO) and I am finally
happy with my “THE” camera. No more shopping/comparisons, reading reviews, looking at flickrs. I can finally rest and go take pictures.
Thanks for all the great m43 communities.
there is also Panasonic 100-300 …and what I read its better/cheaper and bit faster at tele end then oly 75-300
Good one. I hope you won’t be disappointed with the E-M5. If so blame me!, but I hope you wont be. The 75mm f1.8 is definitely on my get list.
Cameraland is awesome. I have bought two Fuji cameras from them in the last two months, and they are a top notch company.
