The camera shops in Chinatown are mainly tourist traps :)

I will avoid buying any electronics items in the area...other things are not so bad

There are quite a few Singapore guys here in Pentax forum (including me)..


Generally, if you are looking at the new DFA lenses, US will be cheaper than in Singapore. Any lenses you have in mind? Maybe we can advise you on the price easier..


On the must shoot locations, I supposed most tourists in Singapore will be shooting the Marina Bay Sands, Garden by the Bay, Chinatown


The pentax community do organize gatherings once awhile so maybe you can join in one if the chance arise

at 50mm f2.8


IMGP1523 by Unforgiven28, on Flickr



at 90mm f8


IMGP1499 by Unforgiven28, on Flickr



at 135mm f8 (after some pp to clear the vignetting)


IMGP1500 by Unforgiven28, on Flickr

i would say that at 135mm, this is the only focal length that we can really use the lens on k1 although i did take another shot at 115mm which only shows very slight vignetting after some pp



at 115mm f2.8




IMGP1688 by Unforgiven28, on Flickr

---------- Post added 11-16-16 at 07:12 PM ----------

not much difference at 135mm for f2.8 and f8..the vignetting clears up quite well after some pp


135mm at f2.8

hmm...i just saw that also..this was one of the last few shots that i took that day so i cant really confirm that..i have to wait till the next time i shoot before looking at it again...

---------- Post added 06-02-14 at 03:26 PM ----------



i dun have the DA40 so i cant really comment whether the 20-40 can replace both DA21 and DA40...but when i got the 20-40...i did try to sell my DA21 but there wasnt any takers..so i decided to keep it for now...but still i cant see myself keeping both DA21 and 20-40 in the future..so most likely DA21 will go if a buyer show up

pentax 31 is one of the best, if not the best, lens that Pentax had made...even for me..if it really boils down to just owning just either the FA 31 or HD 20-40..i will still choose FA 31...but then if i can keep both lenses then why not...for me..the HD 20-40 is good enough even tho its not the best :)

here are 2 more shot on f5.6 for those who might want to compare both lenses stopped down

Meanwhile here are some pics taken at either 20mm or 21mm on the DA20-40..they look good enough for me :)

posted this in another forum before...DA20-40 vs FA31..at web size viewing, i dun think you can really differeniate with DA20-40mm at 31mm, f3.5 and FA31 at f3.5. However if pixel peep,i feel that the FA31 is slightly sharper in the center
