Reacquired the CV 75/2.5 Color Heliar. I owned and sold it while I was using the K-7. I just bought it again to test because when I reacquired the Nokton 58/1.4 to try out on the K1 (which I'd also used on the K-7 and K-3 but sold), the Nokton metamorphed into one of the finest lenses I've ever used, as though it needed a better sensor to really show its stuff. First shots on the K1 suggest the same is true for the CV 75, and well lives up to its name color Heliar.

Here's a shot at a local fruit market wide open:



Shot below shows it is sharp from corner to corner at f2.5 as well. Full:

I think you know the Voigtlander 90 SLii version is one of my all time favorite lenses, but so far I'm liking the Leica better. Like the CV 180, the CV 90 is super sharp, and has great color, but it doesn't quite perform as well with micro contrast as the Leica (or Zeiss), plus I prefer the "gentler" resolution and acuity of Leica. I am not in a rush, but I will probably be (most reluctantly) selling my CV 90.

I think part of it is how much I like 90mm focal length, but the lens' IQ is also blowing my mind. The shots below I took at the grocery of a dog ostensibly guarding a steering wheel :). It's a low contrast setting but in the crop you can see the lens' way of smoothly capturing much detail:

Indeed!

By the way, I saw in one of your posts about using a Leitax adapter that you said ". . . it seems that you cannot focus to infinity with Leica-R 90/2 AA"

I'm not sure what "AA" means, is that aspherical? Anyway, at first I thought the R90 pre-aspherical didn't focus to infinity because some shots were blurry at infinity. But then I noticed that in other pictures (like the one I posted above) that the R90 did focus at infinity. It turns out that on my copy the lens turns a mere 1mm past infinity, and at wide apertures that makes it very difficult to hit focus just right. Now I just set infinity focus at the minus 1mm mark, which I've identified on the lens' distance scale, and it works fine.

Hi Dave,

I can't de-private my Flickr account right now. I wish I had more time for thorough test instead of just running around at lunch time taking snap shots. Even so, the R90 seems destined to become my favorite.

I don't know if this will help, but I've posted the full sized Vario 35-70 shot I cropped here. Since the Vario was zoomed at 60mm, the full sized picture at least shows how much more I had to crop to match the R90 crop. I also replaced the vineyard pics of the upper post at full size.

More shots testing the R90 pre-aspherical at F2. The rose shows a bit of Leica "glow" . . . unfortunately it's just a foot in front of a very rough plaster exterior wall, so while the lens is not showing its full bokeh potential it does suggest just how well the lens can perform.

Next a test for sharpness at F2 with the bee. I captured two bee shots in focus, the first is uncropped, and the second is a crop of the second photo (but same bee) because it shows detail better. Seems quite impressive to me.

Lastly, I shot a landscape with the R90 at 5.6, and the same scene with the R Vario 35-70 also at f5.6, but zoomed to 60mm; I then cropped them the same. Of course it's not a fair comparison with the R90 having a 30mm advantage, but the Vario came pretty close anyway.

I've read good things about the R 90/2, including that it approximated the legendary R 80/1.4 for bokeh and glow. The author of this article on the "Leica glow" highly praised the R90/2 when he said, "Summicron 90mm f/2 Pre-ASPH is the most subtle, and it glows only wide-open. The glow is complemented by a beautiful bokeh and high micro-contrast. Arguably, this lens has the most iconic “Leica look” signature." Alright then!

Toward my tastes were also the advantages of the R90/2 being much smaller/lighter and half the price of the R80/1.4. So when I finally got a late model R90/2 all Leitaxed and ready to go yesterday afternoon, I ran out to take a test shot hoping it would live up to expectations. I need to use it more, but the first shot at F2 was encouraging:

Yes, I see the logic of it. Reflecting a little more on my motivation for suggesting Leica have its own review category . . . I think I've been moved by what a difference the K1's sensor has made to lenses I used on various APS-C cameras. For example, I owned every CS Voigtlander while using K-7 through K-3. They were my favorite lenses but I sold them all looking for something "more" I didn't know exactly what was.

After I got the K1 I reacquired some of the Voigtlanders and wow, what difference it made to have a sensor that could take full advantage. Same thing happened with Zeiss glass, and now Leica. In the realm of full frame lenses, Leica offers a most unique rendering that I thought a lot of Pentaxians owning the K1 might be overlooking. Thus, I thought separating Leica out from the crowd would help reveal missed opportunities there.

Lol. I'm trying to point out that Leica lens reviews are dumped in "Miscellaneous" instead of having their own "Leica" category (like, say, Zeiss or Voigtlander), and that given the quality and history of Leica it seems more fitting to assign them a distinct named category.

Very little you say seems relevant or makes sense including "I don't care one way or the other" since the rest of your post suggests you do care, and in a rather uninformed and prejudicial way.

If you try to buy Leica lenses you will see just how competitive the market is for some of them. Or, if you really wanted to, you could have searched online for the great number of enthusiasts, articles, Flickr contributors, etc. and then offered a more thoughtful and informed comment. It's hard not to judge yours as an opinionated rant because it sounds like you know absolutely nothing about Leica (which you basically admit/reveal over the course of your post). You aren't even Leica-informed about this site since there has been a Leica lens club going on 10 years now (where BTW I have posted, as well as in Reviews). And why the straw man? Didn't I suggest it's not just about historical importance when I said, "a separate listing needn’t be merely for nostalgia or veneration sake. Since Leica is the architect of some of the finest lenses ever made, its own review category might encourage more to try and review the lenses"? Neither did I say Leica lenses are "the best" as you falsely implied (I expressed that SOME are finest lenses ever made). While I'm complaining about your rather rude post, I must say that last I looked you aren't moderating here, so seems arrogant to say "Start a club for Leica lenses so we can see what all the fuss is about. Things can go from there."

As for you "not [knowing of] Leica's in the park after 1935" meaning anything whatsoever about Leica lenses (unless maybe you are the god of lenses), I suggest you study up on current Leica offerings before you say such things. Leica R models are discontinued, but they were made up to 2009. (FYI, a number of R lenses are over 90mm. However, of what importance are gaps in a lens line up in terms of trying out lenses that DO exist???). And Leica still makes Leica M, mirrorless SL, medium format, etc. Leica is alive and well, AND available for Pentax (which for me, after the K1 came out, majorly ramped up my interest in FF classic lenses). That you do not appreciate the Leica "look" so many others value is about you, not Leica. Just like that I do not appreciate Pentax lenses so much (and that's after trying every single Limited and most star lenses) . . . is about me, not Pentax lenses. Your tastes in lenses (or mine) are not the judge of greatness, nor are pop culture opinions, or what you last heard mentioned anywhere, or experience with wealthy clients (a weird thing to say anyway)

Other reasons why Leica deserves its own category? The love of Leica can border on obsession for those who appreciate the ability of some Leica lenses to highly resolve but gently so; to produce the Leica look or "glow" as described in this article from a favorite site, The Art Photo Academy. Lenses with personality or that lend themselves to artistic renderings appeal to some of us more than razor sharpness that seems to be the primary IQ judgement standard for nearly every freakin' modern lens review in the universe.

What do you think—that this site will be denigrated by separating Leica out from the "Miscellaneous" category? What makes doing that so "special," as you say, when even Quantaray :fedup: and Russian/Zenitar have their own separate categories!

I would like to suggest having a separate “third party” lens category for Leica lenses. Leica R lenses (and Leica M39 screw mount less ideally) are quite adaptable to Pentax either using a Leitax adapter (Leitax lists some 45 Leica R lenses and variations that can be adapted), and there are several less expensive Chinese adapters such as these.

Leica is the grandfather of 35mm photography, as discussed in this article, so it does seem Leica lenses deserve a bit better than being unceremoniously dumped into the “Miscellaneous” third party category. However, a separate listing needn’t be merely for nostalgia or veneration sake. Since Leica is the architect of some of the finest lenses ever made, its own review category might encourage more to try and review the lenses.

Edit: I'm referring to the Third Party Lens Reviews section of PF.

Testing the Leica 35-70mm/4 at 70mm, which I have read somewhere is its weakest spot of the zoom. But a crop of the shot below at f5.6, at least in terms of sharpness, looks good. I actually decreased the default sharpness setting in Lightroom. The K1's meter reading resulted in a dark rendering, but I like it:

Not mentioned are lenses using lanthanum, like some of the old Voigtlanders. I'm not sure if the modern "Lanthar" Voigtlanders (Cosina) I own actually contain lanthanum or if it's just been left in the name. In any case lanthanum is said to be "only 1/10,000th as radioactive as thorium."

There's a long list of lenses that test radioactive found here.

I at last realized my confusing JPEG vs DNG results when testing space used on my memory card was due to misreading my menu setting. I chose DNG as the general type of file for RAW, and thought I'd set my picture taking to DNG when it was still set to JPEG for active use. After I compared correctly my figure for JPEG was 1386, and for DNG it was 398.

I mean looking in the viewfinder, lower right, there is an indicator that shows what ISO setting one is using. Immediately after I shoot, a number appears briefly, and then returns to the ISO setting. I've tried it with both JPG and RAW, and it behaves the same. I figured at first like others are suggesting, that it's indicating the number exposures left on my SD card. But that doesn't quite make sense because the number is the same for both JPG and DNG settings.

I've searched everywhere for what I suspect is a simple answer, but can't find anything. I recently noticed that while looking in my K1 viewfinder (I only shoot in AV mode) that after each shot my ISO slot registers a number that decreases by 1 with each shot. It seems to start out at around 1394 and goes down from there. It usually resets to 1394 if I change lenses, but not every time. Can anyone explain what this number indicates?

Thanks

The only Zeiss lens I've owned that comes in the ZK mount, but which I bought Leitaxed instead was the 21/2.8 (I now have two other Leitaxed Zeiss lenses - 25/2 and 135/2 -but they aren't made for the ZK mount). I believe I paid $890 for a near mint 21/2.8 ZF.2 version that I had Dave (Fenwoodian) Leitax for me. Now that I've used Leitaxed lenses extensively, I wouldn't hesitate to buy one I really wanted because using them is no hassle. On ZF.2 models, one still gets focus register (which I seldom use anyway - find my eye better at focusing - and if one can get by without focus register, the 21/2.8 ZF can be had for a real bargain), so one only needs to deal manually with F stops . . . and it's simple! I typically leave the lens at F4; I can see and focus easily there, and then if I am shooting on the fly I just count the clicks to get to 5.6 or 8 etc. But since the 21/2.8 is used primarily for landscapes, it isn't especially important to adjust F stops fast and focus is typically at infinity anyway. IOW, I don't why know more people interested in the superb quality of the 21/2.8 don't grab a ZF.2 version at half or even 1/3 the price on Ebay.
