Hi

 

I have just bought a M 240 which will be in my hands with a 35mm lux fle in a week.I came from Nikon d3x and d800e and lenses like coastal optics,zeiss zf line and Voigttlander 125mm apo lanthar.I will be still using them for close up and macro work in nature.

I will be using leica mostly for travel,portrait and street photogrphy.

I have a setup in my mind which has 21mm elmar f3.4 and 35mm lux at wide side but i am a little mixed at the tele side.

You can call me pixel peeper or leica is not a good choice for a pixel peeper etc. but please let me know which has better optics,corner to corner sharpness starting from wide open apertures etc.Which is a better corrected lens and which has more leice look or pop rendering.75mm apo or 90mm apo?

Please halp me on this.

Thanks

both are EXTREMELY good. even for the most meticulous pixel peepers, the difference between the two is negligible. performance wise, the 90 APO is perfect! and 75 APO is just nearly as good. what will determine your choice is your preference between the two focal lengths, nothing more in my opinion. As for me, i'm a 35-90 kinda guy ;)

It really comes down to which focal length YOU prefer. Both lenses are brilliant but have their trade offs.The 90 is supposedly the better performer. The 75 was quite a wavy field curvature.

 

I went with the 75 Summilux and it's one of my favourites. I'm going to get the 90 APO as well.

I had the AA 75, and struggled to focus the thing - it really annoyed me, so I sold it. Many others don't have this problem with it (look at Geoff Hoppyman's pictures).

 

I now have the 75 Summilux and the AA 90 Summicron, and I'm very happy indeed ...

You cannot go wrong with either lens if sharpness is a prerequisite for you.

At f/2 both of them are a bit soft on edges and corners whilst at f/2.8 and on they look equally sharp with a slight superiority for the 90/2 asph but this is not obvious.

None has significant distortion, vignetting nor CA issue.

None is immune to flare either but i don't find it disturbing personally. Not everybody shares this opinion though.

Bokeh is rather contrasty with both lenses but doesn't look too harsh in my view.

I've heard that the 90/2 asph might have coma problems in some lightling conditions but i have no experience with such.

Both built-in hoods are rather useless when a filter is on.

BTW if you want the same level of sharpness with a smoother bokeh and a more efficient hood try the tiny 90/4 macro or the last Elmarit 90/2.8 which is a bargain by comparison.

Had them both and much preferred and kept the 75/2 apo - compact and a super performer.

 

A 90/4 is a great little lens and with the macro attachment gives a flexible and compact combo.

 

I would always forgo a bit of speed for small size and portability ...... no point having a lens if it's a pain to cart about and you end up leaving it at home....

I also have these two lenses and fully agree.

Have the 75 2.0 for a week now. Brilliant close and far, sharp, nice colors. It is hard to focus and I have been using Leicas for 30 years. The 90 will be worse.

 

I have a 90 4.0 and it is a wonderful lens, but again hard to focus probably because of the .68 finder instead of .72 which they had to use because of the thicker body I am guessing.

 

The 90 AA needs a redesign with floating elements to improve close focus sharpness.

 

The 90 4.0 is sharp close and far and is better to carry. Collapsed it is about the size of a 50 2.0. It is a great lens except when you need faster.

 

It really comes down to if you want a 75 or 90.

Have 75 AA (and Lux), and 90 Elmarit.

 

Love all my children. That said if only one, prefer 75 as it meets more needs and can go longer with cropping. 90 can't go wider.

 

Lately, using 75 and 135 for tele combo. YMMV

Both are superb lenses but 90 APO is better from what I have gathered so far. I do not have a 75 APO but I love my 90 APO and I use it with a 1.4x magnifier.

 

For travel, 75 APO would be great with a 28/2.8 however it depends on what you prefer. Both would deliver outstanding images...hmmm...I thought I only needed a 21 SEM...this thread is tempting me to get a 75 APO :rolleyes:

If you are into portraits, it might be wise to forget about ultimate edge to edge sharpness on your short tele and enjoy some old skool character with the 75 Lux. It's not shy at landscapes when closed down, either.

The 75 Lux is not exactly shy at landscapes fully open, either - facing dawn | Flickr - Photo Sharing!

I love my 75AA, perfect combo with my 35 Lux ASPH FLE.
^ +1. I've read (mostly on this forum) that many consider the 75/2 ASPH to be as good as the 50/1.4 ASPH. I have no clue as to the veracity of this but I do know that the 75mm focal length works really well with a 35mm lens.

 

I generally use lens combinations of 28 &50mm and 35 & 75mm depending on the kind of scenes I expect to encounter on a given day. I often use the 35 & 75mm for travel and replaced a 35mm Summilux with a 35mm ASPH Summicron for this purpose. I think the 75mm/f2.0 is a great lens, it's compact, has a short focus throw, and renders brilliantly. Also you can always crop to a 90mm view from it. Even the horrible slide-out lens hood that Leica unaccountably puts on some of their lenses works on the 75mm - it actually locks! :)
