I noticed with both the 21 SEM and 28 Elmarit-M on Saturday that I was getting this polarizer-like effect in the sky - without any filters. Interesting?



i definitely get different blue skys with my leica m lenses, but that looks more like uneven exposure on one side of the frame (branches are also darker). i sometimes have trouble with that on my 7 with very high shutter speeds and no first curtain.

I used Adobe FlatField to get rid of the color shift. But, not vignetting, so that probably played a part.

Looking at my other pictures, it's not as pronounced. This one may have had to do especially with the angle of the sun and the normal vignette produced by the lens (this was at f/2.8).

Oh interesting, sebboh - you're right, this one is at 1/4000. But, I have the electronic first-curtain shutter enabled. (or is that what you mean?)

that's what i meant. perhaps the electronic first-curtain can't sinc well enough at such short shutter speeds?

Next time I see this happening I'll have to try with/without it.

@mawz, I had no idea the 50 1.8 rendered OOF areas so well. That lens looks quite nice for near focus too.



taran, note this is the relatively rare 'long-nose' 50/1.8 AI, not the very common 50/1.8 'pancake' design available as a Series E, AI-S, AF, AF-N and AF-D lens. The long-nose is IMHO optically superior to its successor (as is the 50/2 design that the long-nose 1.8 is derived from). My experience is the long-nose is sharper and has nicer bokeh than the pancake.

The NEX-7's electronic first curtain shutter does have some known consistency issues at high shutter speeds. I disable it for this reason if I'm expecting to be over 1/1000.

A quick test here at home confirms - at 1/4000 (and iso 16,000 since it's pretty dark), the bottom of the frame is quite a bit darker than the top. With the electronic first curtain disabled, it's the other way around, which matches reality. For the picture I posted on the last page, I had the camera oriented s.t. the bottom of the frame became the right side of the image.

Meanwhile - more pics from Saturday.

Took this one in our garden at sunset with the CZ 45F2. The wife loves to collect skulls and old bikes and trikes for the garden. I decided to combine the two this afternoon. Color Efex for som PP Fun.

not one with any artistic value, but I got the 90/2.8 G Sonnar this evening and caught a quick glimpse/shot of comet Pan-STARRS, so I thought I'd share. Maybe someone with some longer glass (and prettier horizons) can grab a nicer shot in the next few nights?

Great comet shot!
Here are some tests of the pre L Canon FD 300 2.8 SSC on a Nex 5n,
both at 2.8

Wow, you guys continue to astound me with the quality of shots you post. I went down to the river the other evening and got these with the CV15.

Awesome bokeh in the highlights.

JimParsons,

Really nice shots.

ZE 35 1.4 stuck wide open until I get a proper adapter.

Sorry. There's a couple on ebay that may go for a decent price if that helps.
