Leica APO-Summicron-SL 90 f/2 ASPH Lens (11179)

Its quite a mouth full, but Leica has started shipping this lens, I managed to test one recently, so here is my review.

Lets start with the specs:

The Leica Tri-Elmar M is Leica’s only wide angle three position zoom. Is it a zoom, well sort of… It is a lens with three distinct positions, and it only performs well at these specific focal length positions. We have a lens that covers 16mm, 18mm, and 21mm focal lengths. We are going to look at its strengths and weaknesses…

It is arguably one of the best wide angle lenses in the world, easily holding its own today. A few other wide angle primes are better, but they are primes, they’re supposed to be better. If you want a small unobtrusive wide angle lens then this maybe your ticket.

For this test I used my Leica 24 megapixel M240. The M240 only records an approximate aperture value. There is no electronic link with M lenses to the camera. Yes, there is a 6bit coding on the lens, but that only tells the camera what lens is attached. No aperture information is passed. When you examine the files you may see an aperture value, again it is only an approximation. I did record that actual aperture values used in this test independently.

Check out this link on UV filters. After a blurb on UV light and its effects, they test the best and score them according to UV ray reduction. One thing that they don’t test is durability… UV Filter Test

Getting Ready

Ah the joys of Travel in this modern era. Today. getting ready for any trip requires a ton of preparation. What lenses do I take, which camera bodies, how much weight am I willing to pack around, what to check, which bags – well you get the idea.

The first thing that you need to do is make a list of the places that you want to shoot. Once you have this list, then get a map and plan the best route. Do this east to west, north to south or the opposite, so that you can change your route at the last-minute, according to weather.

Next, I try to create a shortlist of hotels for each location where I plan to stay. This is usually determined by either sunrise or sunset shooting, or both. Remember to get their addresses prior to leaving. Driving should be planned at the poorest light time (usually the middle of the day), and do not under-estimate the time required to travel short distances in other countries, I have seen 250km take 7 hours in India for example. If you are planning to drive, then a portable navigation device is a must. You can preload destinations, shoot locations, and add tons of other valuable info.

I then check Internet sites such as pbase against my list of locations. These websites are excellent for finding out what locations, lenses and focal lengths that have been previously used by other photographers. Also remember to check out Google images, it can help with unique viewpoints. Check out each location with Google maps, this can tell you compass orientation for sunrise and sunset. I also use this for mapping locations for set up.

Buy a guide book before you leave, personally, I like DK books, but you may have a favourite. These books are invaluable for guiding taxi drivers, guides etc… Consider a few Apps for your smart phone, I find citymaps2go invaluable
