Originally posted by UncleVanya Now that is a rational response. I may disagree, but at least it is a reasonable compliant. The prices recently increased I think to to the yen which I why I suggested looking at used pricing but I agree the prices for m4/3 seem high at times. I personally think the excellent Sigma 19mm or 30mm f2.8 is a more budget friendly lens in that focal length class if buying new. I own the 30 an older Olympus 17mm f2.8 myself. Both of those are image quality equivalent but slower than the 25 f1.8. I wouldn't bother trading up myself at the moment. The cost vs benefit is low.
The reason people may pay more for m4/3 lenses is not a single factor but I think the high quality to size is a large part of it. Also the very modern designs play a role. For super budget use the ease of adapting manual focus film era lenses from nearly everything is a different route that many take to fill in gaps at low cost.
There isn't that much correlation between format and the price of a lens from M43 to FF, imho. Maybe MF is different - I don't know.
Some lenses (or brands) benefit from huge advantages of scale while others position themselves as offering superior quality and build for superior prices. Cross comparisons are pretty difficult sometimes. One has to decide what one wants from a whole _system_ and the compromises one is prepared to make. Many folks simply don't want big cameras and lenses. Even if they could put up with the physical problems which ensue or the hassles with airline carry-on regulations and the like, and of course with the expense, they don't print large or even much at all so big high-res sensors are of very limited use to them. But, often, they do want quality. Outfits like M43 or Fuji have gotten adept at delivering it across a range of price points.
Where I live the Oly 25mm is about the same price as a DA 40mm and thus quite a lot less than the other DA prime lenses (the 40mm is the cheapest one). That's a full but still fair price, in my view. I am getting a well-made modern design, sharp wide open, with a fast focus motor. I suspect that a newly designed DA 40mm with those specs would cost quite a lot more, in fact is certain to as we'll see when Pentax release new DFA prime lenses for the K1 in 2017. They are unlikely to cost around 300-320 bucks which is what the Oly 25mm/DA40mm go for here. My guess would be twice that or more.
It's all relative. If a very costly lens delivers the goods for someone then it is doing its job and may offer exceptional value so far as they are concerned. Olympus offer a 300mm prime lens for around 2500 bucks. It is extremely well made by all accounts, offers exceptional image quality and is fully weather sealed. That's quite a cheap lens, in fact - when you compare it to 600mm equivalent prime lenses of a similar build quality on other systems.
Just bear in mind that these days
award-winning images can be taken a Go Pro. That puts into some perspective all the nonsense in the camera industry trying to talk people up into spending $$$ on big-sensor bazookas they just don't need.
