Lens cap 15mm v 14-42 2R
 
Tested both at 15mm f8 and f 4.5 . Nothing in it both just as furry.
Fine for general holiday pics if you don't need to crop.

Now all have a nice day

Surprising result - any chance you could load some examples?

will have a go. Three images 15mmcap 15mm on 14-42 at f8 and f 4.5.
I then tried the super sharp Samyang 14mm about the same ...so I put it down to the sensor . results very similar to using a 16MP D7000

Fury or furry? I guess furry.

Thanks for posting some practical examples to back up your findings, it's most appreciated. You're right, there doesn't appear to be much in it - although you'd really need 100% crops to be conclusive. If results are similar to a D7000 I'd say that was pretty good!

There, you see? It appears we can have a sensible discussion and I thank you for that. *chr

I always have a sensible discussion . Its just when people butt in who have not read the post and have no experience of the lens "contribute" I sold the D7000 many years ago, good for its time but compared to the modern cameras it was junk. ( 16 MP with low pass filter does not cut it in 2018)

In your opinion, what is the minimum number of pixels required to cut it in 2018?

I would happily live with 10MP as they would love low light...

I looked on Flickr and there are 174 million images there taken with the D7000 - it's the second most popular Nikon model in terms of total images and the fourth in terms of current posting frequency. The gallery of images taken with it has lots of super imagery. Far from junk IMHO.

Someone mention Fury? Here he is:

There's good evidence to show that fewer pixels is not necessarily better for low light. For instance, the Sony A7sii (12Mp) is no better than the A7rii (42Mp) when looking at the overall noise on images at the same magnification. The noise per pixel will be lower in the A7s, but the A7r's pixels will be downsized to generate an image of the same size which reduces the SNR overall.

At that magnification in that light and with a "SOOC" jpeg, I'm sure a picture taken with my 4 year old Samsung Android phone would look the same.

Interesting though it's tough to see much detail in those reduced images.
I picked up the 9mm bodycap a couple of months ago. It can do some great things but there is quite a lot of purple fringing which is obviously less apparent if you shrink down to 800x600 ;)


It can produce some great images in good conditions.

For a walkabout I would still choose the 17mm f2.8 or the 14-42mm EZ pancake but it's interesting that the 15mm body cap is capable *chr

Any camera can produce junk if in the wrong hands. :)
