Nikkor 180mm f/2.8D AF IF-ED Review

The recent surge of activity surrounding prime lenses has yet to reach the classic primes with focal lengths above 100mm.  Only the exotic “Super” telephoto lenses have been updated in recent years, and at a frequency that hardly seems reasonable. Meanwhile, moderate telephoto primes from all equipment manufacturers grow old and dusty on store shelves as the years pass. The 180mm Nikkor lens is an example of this decades-old trend.


Leica 28mm Summicron-M ASPH Review

The 28mm Summicron ASPH is both a landmark optical design and one of Leica’s most appreciated lenses out in the field. It is to date the best combination of quality, speed and size for the versatile 28mm focal length – the perfect documentary lens. What’s more, not only is this Summicron nearly the perfect lens technically, it is also a very pretty object to behold.


Data for the new aspherical 50mm Nikkor

Photozone has tested the new Nikkor 50mm f/1.8G.  See the data here.

This lens is just about perfect but focus shift is a more than hoped for.  Still at this price it represents a shocking value.  Kudos Nikon!

I look forward to torturing it.  :^)

There are (still) no telephotos for me

The world hasn’t really changed since the last time that I wrote on the subject, and I haven’t really changed either so I’m still stuck.

This lens is 15cm long.  It’s the telephoto that I want.

More after the jump.


Lots of eye candy

See one of the first reviews of the 1.4/35mm Distagon ZE/ZF.2 hereAnother one here too.  There's a lot to take in there.

DXO Reviews the Sigma 85mm EX

You know I've had issues with the DXO lens reviews for a while.  I didn't pay attention to them at all until they posted low-ish scores for some lenses I personally knew to be stellar optics.  These optics I would always choose to use over alternatives they ranked higher.

Since then my thoughts have been that they cannot properly assign value to the contrast delivered with the resolution.  Because that is what I value most, in terms of optics, then their reviews aren't super useful to me.  They also ignore physical aspects of lenses pretty thoroughly but that is stated up-front so I don't begrudge them that.

Zoom forward to now, and with their latest Sigma 85mm EX posting they said what I expected them to.  They found it to be one of the best lenses they've ever seen.  Indeed, I mentioned extremely high sharpness in my own review before basically failing the lens on contrast and usefulness in difficult lighting situations.  So we have another DXO review I find of dubious value.


Leica 90mm Summarit-M Review

The 90mm Summarit-M is the only reasonable “long” lens for the unreasonable M system, that is both its claim to fame and explains why it doesn’t appear to be very successful in the marketplace.  This Summarit also serves as the replacement for the venerable and universally loved 90mm Elmarit-M, a lens that is difficult to replace in the minds and hearts of longtime Leica photographers.  As a result the 90mm Summarit-M is a lens that is appreciated in relative silence vis-à-vis the Internet.


Floating Elements Are Required

When I tested the Leica 90mm Summarit-M (review) I experienced what I consider to be severe focus issues. The lens back-focused at long distances (10 meters or more) and front-focused at short distances (less than 1.5 meters). This caused me to suspect my rangefinder, which I confirmed had grown a small error, but the lack of a true solution after a round of tweaks forced me to research the subject of focus a bit more.

Now I understand the overarching principles just well enough to convince myself that the behavior I observed in the 90mm Summarit-M is by design.  It's not because it is desirable behavior, but because correcting it is an expensive affair. This is what ultimately is going to prevent me from recommending the 90mm Summarit-M to all but mirrorless camera users.


Summicron Examples at f/5.6

A friend of mine asked out of honest curiosity what the difference was between different pieces of high-end equipment. He asked from the point of view of a photography outsider.  More precisely, his real question is what does equipement worth $11K do that equipement worth $3.5K doesn't do?
