Not really an extensive test, or one carried out under contrlled conditions but some close up shots from each lens. Just for fun I'll reveal which was which later:

Lens A at f2:

Lens B at f2:



Lens A at f2.8:




Lens B at f2.8:

I don't see difference except the focus point changed between each shot. You really need a liveview Wink
How was the spaghetti and the wine ?
I don't have any of those lens so I guess
I prefer B=nikkor but would be happy with A=mir

It is very difficult to tell which is what, for a number of reasons:

- small resize (100% size is essential to any predicting)
- artificial light (kills colour subleties and colour is a key factor for MIR)
- automatic white balancing in the machine evening out colour differences
- machined tools as subjects (it's easier to judge on natural objects, machined tools make all lenses look equally sharp)
- simple background (no objects in bg to evaluate)
- #2 has different focus points so direct comparison impossible

Based solely on the quality of the blur in the first image (without the other parameters described above), I'd say Mir=A - but it's more a hazard than an educated guess.

I had to move the tripod slightly to try and equalize the slightly different field of view, and yes the focusing was a little out Wink

Both were excellent - Spaghetti with sinach, chickpeas, garlic and olive oil, dressed with parmesan and (sorry Orio) a Californian merlot.

As to liveview, if you can persuade my wife I need a D300...

Points taken, I'll bear them in mind for future comparisons. Both lenses are in my eyes superb performers anyway.

PLease note, I don't want to be picky or difficult - it's just that telling one lens from another is a very difficult sport, and for giving a choice that is reasoned and not simply casual, one needs to have the most possible information in the image.

100% size, colour fidelity (using fixed Kelvin value instead of AWB) and variety in the background (for both number of objects and distances) are the most helpful indicators.

Don't worry - I wasn't offended, I'm grateful for the advice, sorry if I came across short.

I forgot to say yes A was the Mir24n...

Despite the AWB the MIR shots seem warmer to me...

Any lens comparison test should include a basic distortion test and corners performance (shot ot a brick wall or something flat and with vertical & horizontal lines) this is especially usefull for wide angle lenses Wink

Yesterday in the train, I did this test and I was shocked to see that a Takumar 55/2 had a very pronounced barrel distortion side by side an Helios-44-2 58/2 ...

I look again and again and I can not see any difference in the colouring. They seem identical to me. only difference is that the Nikkor photos are fractionally darker.

I think the Mir does uncommonly well in the comparison, from what one can determine with the two shots. Remember the 35/2 nikkor is one of their more highly regarded lenses - I know I love mine. Then also - compare prices and do the value for money thing. Smile Smile

PS down the road I am certainly going to try the Mir.

Sorry I wanted to mean MIR photos are fractionally darker.
