hi, i was given this litle sigma for testing for few days, so why not take a walk an snap some pics for start. it was my first time for sigma, so be gentle. for now jpeg day will do, i will try some raw etc, since i’m doing kind of review for some photo portal.
so, here you go, some jpeg candids around the town’s old centre.

everything good starts with beer..(iso 400, i think)

all others in iso 100

100% crop from pic above. as u can see, this f/4 lense on dp1 is very sharp, there’s no sharpening applied on crop! well, foven byself is one sharp thing, for sure..

again, 100 %crop from above. i think you’re getting it by now..

.. and ends with good meal. this is iso 800, so it can be used even with foveon.

first impressions:

-it’s small (realy small) and it has 1.7x crop sensor. this i realy, realy like.
-it’s has very sharp lense (28mm eq. to leica format i think) which is sharp (and i mean sharp) wide open. and i didn’t even try raw yet!
-it’s has this f/4 lense which i would like to be faster for true lowlight work, but:
-af is not very good in lowlight, so it’s logical. for good af hunt in lowlight u need lot of light..

i could get original optical viewfinder and lens shade, but i would have to return that quick, so just body for me.

this is day one for now. i will try to test other things in next days.,.
but i can tell you, i can picture myself with something like that. to have option on dslr quality in pocket size, hell yes, rangefinder days are back..

ok, en me je zrajcal na dpreview, da bi probal delat makro z dvema objektivoma, in sicer canon 70-200 f4 l in canon 50 1.8 II (slednjega obrneš naokrog). sicer je problem, ker ima 50-tka manjšo prednjo lečo kot 70-200, in tako dobiš v robiv slike črnino, se pa da s cropanjem tudi kaj pametnega ven dobit. no, takole je šlo vse skupaj:
najprej sem vse skupaj sestavil skupaj tako, da sem obrnil objektiv, ju sestvil skupaj, dal spodaj pvc in preko pvc-ja oblimal s selotejpom (tako selotejp ne prime direkt na objektiv in ne pusti tistega lepljivega sranja na objektivu. me je prejšnič izučilo, hehe). sicer je najboljše dobit kakšen step-up adapter, vendar za prvo silo gre tudi takole.

oba objektiva, pripravljena na akcijo . pršice, pazite se.

zatem sem vse skupaj dal na fotič, postavil na stojalo, priključil sprožilc in vključil mirror lock (vasia hack press, hehe). potem je bilo potrebno le najt modela:

nek ostanek posušenega kaktusa al kaj že, v bistvu v živo zgleda kot kakšna majhna smet.

no, tukaj so rezultati:

70mm, f4

70mm, f32

200mm, f4

200mm, f32

100% crop, 400×400 pix. pozor: očitno sem imel nastavljen najmenjšo resolucijo fotke na fotiču (bog ve, zakaj, murphy pač), tako da bi stvar pr najvišji resoluciji zgledala še ene 2x večje, po mojem. škoda, pa drugič.
no, v glavnem, pri cropu se da razbrat stvari, ki se lahko merijo že v mikrometrih, kar pa ni šfoh, kajneda.
če ma kdo cajt, lahko glede na velikost kaktuska zračuna povečavo, po mojem pride tam nekje med 2 in 3:1. not bad, ha?

še ena umetniška za na konec
