How the sixty dollar console-Nintendo classic mini, costing an arm and a leg?


Summary – Sad story of a sixty dollar console costing an arm and a leg.
quoted from one of Amazon user's Nintendo NES Classic Edition Console review: https://amzn.to/2Gid1mP


I also found similar one from customer Q&A sections @ #Amazon's Super NES Classic item page
Q: Will we ever have a chance to buy this?...
A: ...am willing to pay but when you make it impossible to get except rip-off-bay it makes it meaningless that....


Simply put - Nintendo didn't make enough products and they just kept trying to shutdown the productions because they wanted sell their other main line product like Nintendo Switch.

Here is evidence of what I said was probably true:
Despite the positive reception, journalists were confused about Nintendo's decision to discontinue the unit as announced in April 2017. Nintendo did not say at launch that the system was meant to be only a limited run, and its...

Their products are selling so well but they were simply stop producing the product. Does it make sense to you?

NES Classic Edition


Nintendo NES Classic immediately sold out

The NES Classic immediately sold out when it was first released in November 2016, with resellers charging hundreds of dollars for the popular product.

more details from Scalping and bootlegs section of NES Classic Edition - Wikipedia
This, coupled with the extremely high demand, prompted internet scalpers to buy as many as they could, so they could resell them with extreme price markups. In the US, prices were commonly set between $200 and $500, compared to its launch price of $59.99.

Helios 44-2 58mm f/2 lens sample photos without pp.


quoted from Helios-44 | Camerapedia | FANDOM powered by Wikia
Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union.... Based on the lens Biotar 2 / 58,....

So every version has slight different things like shorter(or longer) minimum focus distance, different aperture blades, etc.

This technical details were only for the Helios 44-2 version.


Helios 44-2 58mm f/2 lens technical details:

type: Prime lens
mount type: M42
optical design: 6 elements in 4 groups
aperture range: f/2 ~ f/16
aperture blade: 8
minimum focus: 50 cm
filter thread size: 49mm
weight: 230g
length: 57mm

I don't much care about this technical details of lens. But sometimes it can be useful.
For example, if I already have same uv filter or hood like this lens, I can use with this lens.
And I'm walking long hours when I do photo-walks. So if lens wasn't heavy, it was very suitable for me. That is the reason that I mostly shoot with prime lens.
So I do check those things from the technical details.

Technical notes:

These photos were all taken with handheld and I used M42 lens to Sony E mount or Micro four thirds adapter so I have no idea about aperture number for the photo.

When I am taking photos, I do use Raw file format. So I need to convert raw file to jpg file and during that time, I do some post-processing--this is kind of darkroom process in developing film.
And when I do this, I don't use any default setting from Rawtherapee--open source software because there has some image modification settings like sharpening, micro-contrast and among other things.
I don't use Adobe Photoshop but this also has same kind of default setting with sharpening.
This isn't important for photography. But this is about the lens--what kind of photo I can take with this lens. So sharpening won't help to know about the lens.


So when I do use Rawtherapee, I removed all the default setting.
I will do these adajustments, if necessary:
 - click the auto button in exposure tab--automatically calculate the exposure value,
 - adjust exposure value, if overall image was still dark or too bright,
 - adjust contrast(between 3 and 18) in L*a*b* adjustments tab,
 - if there have some areas were too dark or too bright which makes me feel unbalance the overall look, adjust the shadow/highlight value.
 - Sometimes, white balance set to auto or slightly reduce the temperature value. Because Sony A7's white balance value was quite terrible when I do use other brand lens--not Sony E mount lens.

I didn't use Rawtherapee because I like the color of Olympus Viewer 3 produced.
I did only adjust exposure value. And then adjust level in Gimp--open source software.

I think it is morning glory or ipomoea kind of flower.
