How to inject a fast lens into an existing line up

I use a classic M6 with a trio of 35, 50mm summicrons and a 90mm elmarit. These fulfill most of my needs, however I would like to add a fast lens that would allow low / no light work, as well as selective focus for enviromental portraits. My problem is economics... a couple of thousand dollars for an extra stop on a focal length that I already own seems stupid. What is the best route to go here? 50mm Noct, 75mm summilux, 35mm ASPH summilux??? Any opinions will be great. Also... is this Idea even valid? Has anyone made this major purpose only to find that the upgrade did not add anything to your arsenal? The Noct' shots on Tony's site were great... any other noct" users out there??? opinions??? Thanks, AL

For your purposes, you probably don't actually need f/1, but it sure

is nice. You probably want to shoot for f/1.4, so a 'lux is the way

to go. The problem is, they ain't cheap. Best bet: check <a

another prominent used Leica dealer. Keep an eye on ebay.<p>

Me, personally, I find that even though I own a Noct., I still use my

35 'cron and my 50 'cron the most. The Noct is heavy and hard to keep

concealed over my shoulder (under a coat) and makes my neck hurt.

Although I don't regret getting it, I only break it out on special

occasions. I call it the "special weapon!"

I had a similar lens arsenal to youself and found myself using

visegrips on my aperture ring to extract every ounce of speed I

could get. I upgraded the 35/2.0 (last non-asph) to a Summilux

Asph and have not taken the lens off the camera since! It is a

truly breathtaking lens. I have shot interiors wide open with huge

light sources in the picture with absolutely no flare. It is "the lens"

of the M line-up.

Hi Al,

I had you problem sometime ago. I had the 35 and 50 'cron. I

eventually traded in the 50 'cron for a 50 summilux and have not

regretted. At 2.8 and beyond there is very little to tell between

them, and I gain 1 stop over the summicron. Compared to a 50 Noct it

is much more economical and a lot more user friendly, more in tune

with the character of the M. I would love to have the 35 'lux ASPH

someday, too.

In your position I would go for the 75mm Summilux. It is a focal

length you do not have and I know from experience that is a great

lens and in my opinion the longer focal lengths are the ones you need

to be faster as you need to be able to control camera shake and they

require higher shutter speeds than say the 35mm. Beautiful for

candids and portraits in particular.

If money is the issue, get a used or third-party lens. Like you said,

you aren't going to use it that often. I have the Cosina/Voigtlander

50mm f1.5 Aspherical for this purpose, and also an old 50mm 1.5

Summarit screw mount.

At the risk of being a wise guy,

 

<p>

 

1) which lens do you use for available light photography the most?

and

2) with which one do you find the aperture ring bumping against f/2

or f/2.8 the most often?

Replace with 1 or 2 stop wider lens and enjoy.

RE: Robin Smith's observation that a fast lens is advantageous in a

longer focal length (in this case 75mm)because it lets you use a

higher shutter speed:

This is certainly a valid argument. But at the same time, greater

speed could be said to be most useful in a wide-angle lens, say the

35mm Summicron, because of the greater depth of field compared to a

50mm or 75mm. also, a lower shutter speed can be used (say, 1/30)

without risking camera shake. All this presumes that the lenses are

all at the same distance from the subject. I find the 35mm Summilux

to be a great available-light lens.
