'lux vs. 'cron comparison

Are the 50mm 'lux and 'cron M equal in optical performance?

Is the 'lux pricetag justified merely by the extra stop?

<p>

Ps. I'm past the stage of "Do I really want/need this very expensive rangefinder system?" I mean I'm really over it. And I do :)

kan detta vara en svensk landsman månne? (sorry, guys, Swedish

question)

To give my 2 cents, I find the summicron lenses (currently only have

the 35/2A, but I've tried the 50 as well) to some of the finest

lenses around. Tack sharp, great color, virtually distortion free.

Sure, that extra stop may come in handy, so ar I've done fine without

it.

On your PS-point. Sure you want it, relative to medium format it is

even darn right cheap! BTW, there are some great M6 TTTL deals on

eBay now, they've seem to have dropped about $200-250 in price since

the arrival of the M7 and the US rebates.

cheers,

In terms of tech specs, the Summicron is marginally better (except, of

course, at apertures wider than f2). The extra cost isn't justified

by the extra stop but by the shots that you can get with that extra

stop that you wouldn't get otherwise.

The problem is the high cost of a new Summilux compared with the

Summicron, about $900 extra at full retail price or about $650 on the

grey market. You have to really NEED the extra stop at those prices!

Of course, you may be able to find much better used 'lux bargains if

you're careful what you buy and from whom you buy it. I believe the

resolutuion performance of the 50 'cron is better, overall, than

the 'lux at apertures from f/2 to f/5.6, after which they are about

the same.

Mike... indeed, optical performance - or, as you say "tech specs" -

are what interests me in the comparison.

<p>

Not really whether they throw in pictures with the 'lux purchase... ;)

I'd like to ask Mike Dixon a question if he's still watching. Mike,

would you have considered the 75/1.4 a good business decision given

what the rest of your equipment looks like? I'm thinking here that

you have the 90/2, a DR 50/2, maybe even a Noct.?

Even at the very fair price that Jack Flesher was asking ($1200), I

could not have justified the 75 'lux as something I <i>needed</i> for

business (considering I already had a 90 Summicron). Of course, now

that I have one, I'd hate to be without it. If I had to choose

between the 75 and 90, I'd be bidding farewell to the 90.

So you made, bad choice.You would not make the choice again.Simple

yes or no...cut the waffle.

No, I made an excellent choice in accepting the generosity of some of

the kind members of this forum (another chapter or two is coming up

within a week!). However, it would have been a bad business decision

to pay $1200 for the lens at the time. If you cannot comprehend the

question or the answer, perhaps you shouldn't comment. (Yeah, right!)
