Comparison between Jupiter-3 and C-Sonnar ZM 50

Thanks for the focusing info Hyun.

The photos from flickr show up fine for me.

Raid: Given the potential differences in J-3's, I'm glad you decided to test more than one of them in your roundup.
 
j3 focus seems fine , but sonnar frontfocuses a bit - wahtever stain you shoose it misses for a little. but also i think it doesnt matter it will not affect photos.

....... I have no doubt that the ZM is superior but it is the cost to performance ratio that also factors into a decision to buy or not to by a lens.

Hi Bob,

After long years of thinking like you, in the above sentence, I came to the conclusion that there is a "catch" in the "cost/performance" equation.

The "catch" is that it doesn't take into account the budget potential of the buyer.

In other words, if you have $5000 ready to be spent in a lens, your "cost/performance" evaluation may be radically different from the guy who has $500.

Who is right ?
No one.

Cheers,
Ruben

Well, yes and no. The buyers budget really doesn't enter into the the equation, that is their own business whether they want to spend all or some of it. They may decide that cost to performance doesn't matter to them and simply buy the most expensive item on the basis that it is the best because it costs the most and hopefully that is so. There are other buyers that may have the money in the budget to buy zee best but choose not to. Then there are likely the majority of people that consume things, be they lenses or other things, that simply don't have a huge budget and want to find the best bang for their available funds. Except for a small segment of consumers, most bang for the money/cost to performance ratio is an important segment of the pros and cons to buying. Both groups of consumers should stop looking down their noses at each other and that is the catch. For most the purchase of an item is a balancing act except for the lucky few. You are right in that nobody can be right or wrong in their choice of how to spend their money.
