Vobluda: I have give a try to Olympus 45/1.8 two times but evenutally sold it as I was not satisfied with its optical performance.It is plain glass with no asph or ed and it is visible on the pictures (and that is the reason why it is so cheap). For now I have Panasonic 45/2.8 that is slightly more expensive than Olympus 45/1.8 but optically superior.From what I can see googling new Panasonic 42.5/1.7 will have asph element (s) and that is the reason why I think that it will be much better then Olympus 45/1.8 though a bit more expensive.
You sure you have read and understand this?http://www.dpreview.com/articles/2666934640/what-is-equivalence-and-why-should-i-care/2
I am sure you do not fully understand the meaning of equivalence when you said"it's still 1.2 while they are 1.8 and not 0.9"
f/1.8 is f/1.8 but it is really pointless without taking the format into consideration
my iphone's camera has aperture f/2.2; so do you think it is better than 28 f/2.8?
Sigma82; you still do not understand "equivalence dof"the canon f/1.8 @ 135 FF is equivalent of f/0.9 in m43
have you checked?http://www.mu-43.com/threads/63080/
You can understand it better if you know how telescope for astro works; focus length and aperture does not really matterthe key is the diameter of the main lens
It is easy to compare dof control; it is not easy to compare dof quality
I cannot convince myself getting 42.5 f/1.2 @ over $1200 USD
especially when the Canon/Nikon 85 f/1.8 only priced at ~$420; and it's bokeh behaves like a 42.5 f/0.9 @ m43 camera....
Well, I know m43 is different from FF....the price of 42.5 f/1.2 is just...way overpriced..
I am very pleased with Olympic 45 f/1.8; it's cheap and gives very good image
Do you think it is better to release a D810AM, equipped with mono sensor where it can merge RBG or RGBL internally from 3 / 4 shots?
sharkcookie: 8% wider than the Nikon 12-24, but the Nikon is twice as fast (one stop equals double the light). The Canon is 50% more expensive.
Exactly; I would say "I use stitching only when its absolutely necessary"
acassino: Needs an articulated LCD.
Prixnobeldefoot: wish they had included a bigger flash, 12m range is a bit short for my astrophotography....
Yes, Pluto is usually too dim; we need a big flash with GN 1 Quadrillion
I agree a lot of shots can be done via Stitching and there are benefits using Stitching
But UWA is UWA, there are shots which cannot be replaced by Stitching
there is really no need to continue this discussion if someone insists stitching can fully replaces UWA
It depends on what subject are you trying to take!
Stitch is ok on static subjects
Stitch does not replace UWA; come on!
goshigoo: 3 mm is huge difference in wide angle
"Can you give examples where the shot can only be taken with f/2.8 but not f/4;"
You can take wide angle Milkway shot even at f/8 or smaller aperture
Yes, I have an ioptron GEM and use my wide lens at f/4 or 5.6 instead of wide open.
We would usually go for the lighter Samyang 14mm f/2.8 for wide angle Milkway shot
I rarely see people using Nikon 14-24 f/2.8 for astrophotography
you can try to checkhttp://www.astrobin.com/see how many photos are taken with nikon 14-24 vs samyang 14mm
so you just gave a really bad example
le_alaincan you give example?
I am talking about zoom lens that covers that focal length continuously
Don't tell me sigma 12-24
This wide angle lens is mainly for landscape shooter, obviouslyDo you take landscape photos?
Can you give examples where the shot can only be taken with f/2.8 but not f/4; please bear in mind that we are talking about landscape
For landscape shots, it's usually taken at f/8 or the best aperture of the lens on a tripod
If you want to shoot 11-13mm in a non-rectilinear fashionthis is the ONLY lens in this world that offers it
Do you know it is a huge difference for that 3mm in wide angle?
3 mm is huge difference in wide angle
goshigoo: I think the new 14mms, like the 20mms, is just cosmetic update
I hope Panasonic release a 14mms f/2 or faster lens even it is larger than the current one (smaller than 20mm)
The 15mm is too big; I want the same as 20mm but larger aperture
sjredo: NEW FULL ROADMAP!
I think we will see Zeiss 85 f/1.4 in 2015
