Originally posted by Gooshin either way people just dont want to admit that alens that got handed to me by a used camera gear clerk from the bottom of some drawer with no lens cap that i paid with the 5 dollars in change i had left over from a night full of partying could even remotely compete with a world famous 400 dollar lens. (and by remotely i mean nearly indistinguishable unless you pixel peep)
someone up top said they could clearly see a difference... yeah.. okay... i guess if you stare long and hard and read exifs you could figure out
but BETTER? or MINDBLOWING? come on...
our "art" is for the massess, people seem to forget that sometimes.
you fail to understand something though ....
Let me explain . A lens that costs 100usd is 90% good . A lens which costs 400usd is 95% . You only pay 5% more quality ( be it resolution , color rendition or whatever ) for 400% more money .
Well you see this is the case *especially* for standard lenses ( ~50mm ) . They are so easy to produce nowadays . Also , Some people pay for build quality . The pentax FA limiteds ( or expensive lenses in general ) are of very good build quality and will withstand lets say a drop on the floor .. or whatever . And in general a good quality lens will have a better manual focussing feeling . Many people shoot only manual focus so thats a big plus .
Then again , you are resizing to 500~ pixels width , so basically you are only comparing lens' rendering and not resolution . So if there are any resolution advantages for the FA limited , you are minimizing it . A professional photographer will require as good as large prints he can get . Another thing is that I hope you do understand that the FA limited outresolves resolution sensor resolution if stopped down a couple of stops , even on the K20D , right ? That also means something .
Hell , I am sure you can take a pic with a digital compact camera with the same equivalent field of view and the quality will look 95% the same as the FA limited , in a 500x500 image size . But a good professional photographer cares for resolution as much as other lens characteristics , such as Bokeh quality and knows how to distinguish these qualities . Do a bokeh test with your chinon and the limited and you will see .
If a group of people are given two photographs , same depth of field and field of view , but one with harsh bokeh and the other with smooth buttery bokeh 90% of people will not be able to distinguish the two photos ( they will look the same to their eyes ) but a good photographer is willing to pay 2x the price to get good out of focus characteristics .
Don't forget that the cost of a particular product is driven by demand and supply . That means that a company will produce 100000's of 50mm F/1.9 ( stolen optical formula too ) , so they will be able to sell it very cheap ( eg 50usd ) . For example , the 43mm limited has a new optical formula , designed by pentax engineers and well ... its a LIMITED so that means its not a mass production product . So this means it will cost more than a mass produced lens with stolen optical formula . But a good photographer is willing to pay for these qualities .
I am willing to take a 1000usd ( hell , make that 1 million ) bet that I can tell again and again a set of photographs taken with your chinon 50mm and a set from 43mm , as long as the pics are straight conversion from RAW , not PP or resized .
Of course there are many times that cheaper products offer better quality than more expensive products , or at least very similar . It really depends how much you want to spend and how much you think that difference worths .
Sorry for my bad english , have fun
