Lens Question 75 Lux vs 75 Cron

[canlogic]

I am new to Leica, just picked up my M8 yesterday.

I am trying to figure out the difference between the two 75's other than the f stop difference. I will use this lens for portrait and also evnt type photography like fairs etc. I have the 28 2.8 and the 50 1.4 lux which would probably work for some portrait stuff but I also want something a little longer so that I am not so "in your face" type of thing. Any thoughts would be appreciated.

I use the Summicron for the primary reason of size. Image quality seems very similar but the smaller lens is much less obtrusive and lighter.

I use the 'Lux, as I need the stop. I've been using this lens with excellent results for many years, but it's an older lens.

There is a newer 75 in an asph formulation. That is also a 'cron.

I look forward to reevaluating my lenses when the M8 arrives.

Thanks for the info, guess I just need to decide whether I need the stop or not.

I've used the 75 lux for some time. I like it for low light work eg in theatres, concerts etc. It is heavier than the 75 cron and it can block part of the viewfinder. However, I don't find this a major problem. If you use it for portraits, it does have a nice slightly creamy signature with good bokeh if that's what you're looking for.

The 75mmf2.0 is a modern design which weighs about half of the 1.4 which is a 20year old design. In fact, according to some, the 75mmf2 is....faultless ! Since you have the 50mm1.4
I would opt for the 75mmf2.

No question: the Summicron is better from a weight and usability point of view. I sold my 75 'Lux to get the 75 'Cron because of these two issues which are important to me.

Thanks for the info. Makes sense to me as I really don't need the extra stop and the smaller size and weight is a bonus although after lugging my 1DMKII and L lens combo they are tiny.

I opted for the cron for size/weight considerations. It is the sharpest lens I have ever used for 35mm photography.

My Lux 75 is a bit unsharp at 1.4. Closed down this is a sharp lens.
