Found out the CV40 suffers from the dreaded sensor stack issue. Not much, but super extreme corners suffer from smearing. Hardly an issue, however the lens vignettes heavily, being a bigger issue.

Other than that, sweet little lens with little compromise. Fantastic for snapshots. Wide aperture keeps it flexible.

My 50mm decisions are over. Would like the sensor mod eventually, however the A7r isn't a long term camera. Venturing into M mount glass is inevitable.

I don't even know where to start with my questions.

1) sensor stack issue?
2) smearing?
3) sensor mod?
4) whatcha got in mind as the long term camera?

1) from my understanding, the sensor is covered with a protective cover, that is xxx thick. If rays hit that cover from a fairly perpendicular angle, no issue, light passes just fine, however, at an angle (wide angle lenses with short flange distance), this can have problems where the cover starts to bend the light and cause
2) smearing. Smearing is just stretched super soft corners.
3) sensor mod is done by a company named kolari vision? They put a slimmer sensor cover. Film for instance, has no such sensor cover, light hits the film directly. Digital cameras have a sensor cover. This is mainly an issue with lenses that have shorter flanges like leica mount lenses.
4) A7r ii or iii, not sure. It has to have IBIS and shutter shock fixed. If it had better low light ability, then that would be even better. I dont want to invest any more into a body I know I will replace at some point, however I can see myself owning a A7r ii if it had the features of the A7ii, which is a terrific camera IMO.

paired with the 100mp, I find that I have great flexibility with a package that's not too overbearing (I can easily attach to a regular belt all day long).

Nice! I'm sure you'll love it! I'm saving money up for another a7 body.. maybe I'll spring for the a7R this time around.

That's interesting, I did not even realize that the hot shoe did not fire off-brand flashes. I'm not a huge flash guy, but I do use off-camera speedlites triggered via YN triggers on occasions for portraits. Will those still work on the Sony?

It does Trigger non Sony speed lights.

Thanks for the detailed reply. Interesting about the sensor "cover". So they replace it with a different one that handles angled light better? Good to know (Doubtful I'd want to do anything like that to my camera though).
I'm kind of glad I went with the A7II and not the R (well, I haven't actually received it yet, but on paper, it seems like the better all-around for me). I'll be very curious to see if the rumored A7rII includes IBIS, a revised grip/shutter button and some fixes to the few things that people didn't like about the original.

I am very intrigued by this Samyang. What's your overall feeling about it? This is the recently announced 135/2 right? They're still only available as pre-orders here in the USA.

Well, according to that video linked to above, they only "sort of" trigger flashes from the hotshoe (have to jiggle the trigger so some of the pins aren't making contact, apparently).

the a7ii is certainly a more rounded camera, pretty fantastic if you ask me. I just want to keep the 36mp, I find that my PC is good enough to deal with it, so why not? Just be patient with the camera, it actually has a crapload of function and configure options. Take your time to configure the custom buttons to your liking, the FN button, and the AF/MF button (mainly if you use manual focus). With the A7ii, I'de probably have a custom button for the stabilizer config/on off, since it's not on lens anymore. I'm almost tempted to just throw in the towel and get the A7ii at times, it's a much more polished camera than the A7r, however I must patiently wait it out.

For now, I'm interested in programmable exif chips for manual focus lenses, if anyone has experience with this, it would help a lot.

Yeah. I plan on taking my time and building my knowledge base very patiently. That's why I started with a native lens. I don't want to have to learn about adapters and manual focusing all on a new camera. First, learn the camera itself, native functionality. Then i'll work myself into new lenses and adapters from there.

Programmable EXIF chips???

I feel exactly the same. And I kept help but feel I should get my a7R up on the market because when they finally do release the a7R II, I'm not sure I'll be wanting my a7R any more at all. Especially if they fix the shutter.

Charlie,
I have a question for you: The Canon 11-24mm is on its way to me (going to take it for a spin for a while to see if I want to keep it), and I am mulling the idea of the Fotodiox ND throttle. Seems like you've been pretty happy with it using your 14mm. Have you had any issues with it. Does it seem to always give a smooth continuous result, as opposed to some of the awful shading that front-mounted vari-nd filters can produce?

Do you imagine it would still do well even at 11mm? Seems like it could be a pretty nice way to get long exposures with such a wide lens as that.

If the ND throttle works OK, then I suppose the biggest shortcoming will be lack of aperture control on the 11-24mm. I haven't tried it yet, but I understand it's not too hard to pre-set the aperture on a Canon lens - Fotodiox has a video covering the technique.

hoping something like that exists, kinda like AF confirm chips seen with some nikon to canon adapters. I just want some exif data, and proper way to notify future cameras about my lenses, like the case of IBIS capable camera. Just saves the trouble of changing focal length settings.

I am convinced that I'll play with more manual lenses, than electronic lenses. My current sony setup consists of 3 manual and 2 electronic lenses. That will probably remain the case for a while. two of my lenses I've considered swapping out are the rok 14 and OM 200, however, not in a rush.

I'm absolutely pleased with the performance of the rok 14 btw, just thinking about reducing weight if possible. 300g savings if I go the voigtlander route, however IQ and aperture, the voigtlander cant match.

the OM 200 I've been contemplating replacing with the canon 200 F2.8 prime. I have excellent 1.4xiii and 2xiii adapters that would make that lens super useful. Would basically turn that lens into a 200-400mm for landscapes, however the weight is not appealing. 300+ grams for the lens alone, and maybe 400-500g for the adapters. 200 feels like plenty for landscape useage, but I get greedy :twisted:

Couple of issues with that adapter....

I'm convinced the adapter is not the same thickness of a typical EF adapter. I get strange field curvature issues with the 14, and it can be problematic (infinity mark changed greatly with adapter). I have specific markers on my Rok 14 to achieve great focus and sharpness, however, if I deviate from that specific setting, field curvature can bite me hard. For my purposes of stopping down and tripod work with the adapter, it works fine, however I did spend some time dialing it in. I had to get the rok 14 stopped way down to F11 to cure all issues, and it does work very well corner to corner.

I havent had any issues with uneven shading at all, 99% of all 14mm shots I've shot since, have been using the ND throttle since I've purchased it. I'm aware of uneven shading with a standard variable ND, and have seen the issue with my 24-70 + variable ND, however the ND throttle does NOT have any of those issues. I would buy it from someone reputable with a good return policy. Not sure how the flange distance may effect the 11-24. It may or may not be an issue. There is a slight color cast, but no more than something like the lee big stopper (probably even less). Light stopping doesnt seem like 1-10 stops though, more closer to 2-8 stops.

Now that I've mentioned it's flaws, it's really great using the filter. I can dial precise shutter speeds quickly without doing mathematical guesswork and dealing with less than desirable aperture ISO settings/ND combos. I just wish that the flange distance was proper. I also have the tough E mount..... I think that changed distances a tiny bit, and some of my adapters wont even fit......

I saw last night that Sony dropped the price of the A7r by $400. Could that be the precursor to an A7rII announcement?

I'm also curious about that ND throttle (read about it yesterday). Wondering how well it works.

Been meaning to ask you, what's the OM 200? The Canon 200/2.8 was on my "want to try" list when I was in Canon world. That's on hold right now as I evaluate Sony. I'd be very curious to hear what your thoughts are on such a lens.
Any 200 is going to be big and heavy (relative to the smaller 35s, 55s and 40s out there). That's a given. To me, that's a lens that I don't necessarily want to carry every day in my kit, but that I will take with me on days where I know I may need that reach. So I don't feel the weight and size is a big deal. I'd put up with that, bascially, on a case by case basis. Ditto something like the Samyang 135 (also on my current wishlist).
