    nomad got a reaction from miran in Metabones SpeedBooster Ultra vs. Zhongyi Lens Turbo II   
    Compared the two (IMHO the only ones worth trying) recently on A7's.
     
    Right from the start I noticed one big problem with the Lens Turbo: it doesn't fit the A7R II, only my A7S due to the small protrusion covering the lens release on the camera. I suppose you could dremel it down a bit, but not without taking it apart if you don't want metal debris getting into the rear area and later into your camera. The lens is fixed to the camera with a twisting ring, which is nice, since there is no play at all. The front bayonet is very tight, it really needs some force to insert your lens, but again no play.
     
    But the bigger problem was misalignment of the whole lens group in the mount: it focuses far beyond infinity (and you loose some range at the near end). It's quite complicated to get at the inner tube to move the whole lens group and even then, you can't get it perfectly adjusted, it only improves to some degree, but the adjustment range is insufficient. While this must not be a deal breaker, you need to keep two things in mind: zooms which are initially parfocal will not be any more with the Lens Turbo and wides angles with floating focusing will loose quite some quality.
     
    Apart from these two problems the optical quality is not bad, much better than it's predecessor and the other Chinese knockoffs. Corners are a bit softer than with the Speed Booster, but the center is sharp and the blue dot issue is pretty much gone under all but the most demanding situations (where the lens itself will flare anyway).
     
    The SpeedBooster was off quite a bit too when it arrived (both were new). It didn't reach infinity, which is a shame for this price level. But it's adjustment is easily accessible and quite simple: you just loosen one screw and turn the helicoid in or out. After some try and error and narrowing in on the right position it's dead on now for my parfocal zooms and reaches infinity just a tad before the mark (which is normal for most still lenses). It's tight both on the camera and the lens, again no play to speak of.
     
    The optical quality is impeccable, very sharp into the corners, just remember that you'll see any weakness of your lenses now (if you've never before seen them full frame). No blue dot problem and no light leaks (they have a recessed and large lens release button, not the usual tiny pin).
     
    So, you definitely get what you pay for: if you want to use it with any lenses worth keeping for todays high resolution cameras, the Metabones SpeedBooster is worth it's price.
     
    And if you ask yourself why I want to use such a thing on a full frame camera: both the A7R II and the A7S deliver better video when set to APS-C.

    nomad got a reaction from Z√© De Boni in Can someone start photography journey using iPhone?   
    IMHO it definitely helps to start with anything that can capture an image! Photography is first of all about the picture, not the technology. Even an iPhone is quite sophisticated compared to the cameras of early masters of photography. One should get an app that allows better adjustment of exposure instead of the standard app, but that's all. I use ProCamera and still enjoy photography with it, even if I own a Sony A7R and lots of vintage lenses.
     
    Photography with such a phone can be quite challenging, more than a camera with exchangeable lenses, since it's very wide. Image composition with such a wide angle and depth of field is difficult, but you can make great photos with it.
     
    Later, with the DSLR, you can learn about manual exposure, manual focus and the different characteristics of lenses.

    nomad got a reaction from Steve C in How close FE 24-70 f2.8 GM at 55mm is compared to FE 55mm f1.8   
    Ask yourself how often you really need the full amount of mpx from the A7R II.
     
    And then maybe get the 55mm and the FE 28 f2, since I second that 35 will be a bit too narrow in many situations. I have both and couldn't be happier when I want to travel light, since you can always crop the 28 down to 35 if needed and the 55 down to a typical portrait length of 85 or 90mm. And I own lots o other lenses, serious LAS, but all the rest is manual and most of them are vintage.
     
    Nevertheless, these will be the two I carry up a mountain…

    I wouldn't say it's totally pointless. I use Slog-2 occasionally when scene contrast ist very high.
     
    But you need to understand that the DR of modern sensors is much higher than what 99% of todays displays can show to the user (normally Rec 709). Consequently, you'll need to make an aesthetic decision how to pull your shadows down (and the highlights up) anyway, like a nice cinematic S-curve. Slog is giving you the freedom of decision in post, while other profiles will burn it in while recording. But for any scene with not so demanding contrast, it's far easier to work with one of the other profiles.

    Really small and light, but IMHO optical quality is similar to the Minolta 21mm (I have both), maybe even a tad better and both are inferior only to the expensive Zeiss C/Y 21mm (among vintage glass).

    I have the version for the Contax G lenses, got it from Roxsen in China (very friendly seller, but not the manufacturer).
     
    Initially, my experience on the A7R was quite frustrating: it hunted and didn't meet the focus at all. Manual focusing via it's motor was fine, though.
     
    I tried to update it as described here: http://www.deoinfinity.com (their new website), but the adapter wasn't even recognized by either an A7R nor an A7R II. Finally, before getting so frustrated to just send it back, I tried with a friend's A7S. It's bluetooth was seen immediately by my iPhone and the firmware update went smooth. 
     
    Now it works perfectly fine on both an A7R II and an A6300 (I don't have the A7R any more). Focusing is as fast as it ever was on the original camera, maybe even faster, and it's dead on without any adjustment. I use both a 90mm and a 45mm lens with it and I really like it!

    nomad got a reaction from Marc Contaxtonikon in prime vintage lenses for portraits/street photo   
    The 60mm Macro can still be had for a reasonable price and it's a fantastic lens for portrait too. I second that most of the slower Contax lenses are great value for the money, but if you're really on a budget…
     
    BTW, the 28-85mm does mop the floor with the 24-70, but that's an easy one. That lens doesn't really deserve a Zeiss label – at least the two I tested. I stayed with the Sony 28-70 'kit' lens as a cheap AF zoom for when I need it.
     
    Sorry to correct you again, I think there never was a 24mm, only the 25 (which is more like 26mm from careful testing against a few other lenses). It's not really bad, if I say "weakest in the Contax line" that's still a very good lens. But landscapers need to know that it needs to be stopped down quite bit to get sharp on the edges. The Oly is sharper on the sides from WO. In the center the 25mm still has that Zeiss 3D feeling.

    Well, I even stop the Minolta 21mm down to 8 or 11 for landscape use. The Flektogon can be better if you get a good copy.
    Unfortunately their QC was lousy, so sample variation is really high. IMHO, a perfect Flektogon is remarkably good regarding distortion, but 'wide' open it's very low in contrast and the extreme corners are not much better than Minolta's.

    I can't comment on the Rokkor 58 1.4 (there is no 55 1.4 AFAIK), but I own the 58mm f1.2. A huge chunk of glass and metal and fu…ing beautiful for portraits, on APS-C in particular. It has that sixties fashion magazine look, if you know what I mean. The f1.4 should be similar, more on the low-con side with beautiful bokeh, glowy romantic WO and sharpening considerable when stopped down a little bit.
     
    The later 50mm f1.4 PG is my sharpness lens, not as much micro-contrast as a Contax and softer colors, but resolution is there and slightly stopped down it's analytical into the corners. It has less glow WO than a Nikkor from the same era.
     
    Regarding the modern Zeiss look, you may want to consider the Contax G 45mm with a Techart adapter, which will give you AF too. It is very close to contemporary Zeiss, more so than my Contax lenses.
     
    Oh, and I'm a fan of that Contax 28-85mm too, kills many primes in it's range! I only wish it had two-touch. But when I need to zoom while filming I use my Minolta 35-70mm (or an ancient Angie on S-16). Once did a very careful comparison with the Contax 35-70mm and – guess what – kept the Minolta!

    I second all these observations and I'd like to add: if you just crop the corners a bit you'll end up with a picture nearly indistinguishable from the 21mm. Just a bit less distortion ;-)
    No problem with a A7R or R II.

    nomad got a reaction from Steve C in Kolari Vision a7 thin filter conversion?   
    OTOH, if I see the the 35mm changing from less usable to just acceptable, while most symmetrical lenses of shorter focal length still have severe problems in the corners, I doubt the importance of it. OK, maybe if you are heavily invested in Leica-M glass. AFAIK, the Sony models without an AA filter already have a thinner stack.
     
    But if you are a lover of vintage lenses like me, and didn't own a Leica before, part of the joy is finding hidden gems making fine images for not too much money. How much sense does ist make to invest 400 to make one or two lenses acceptable when there is such good native glass around now, like the 28mm f2 by Sony or the new native Zeiss models?
     
    Maybe we just need to accept that many symmetrical wides will never be perfect on digital sensors, at least not an Bayer patterns…

    nomad got a reaction from jmr in best a7 for Leica M-mount   
    Those wider rangefinder lenses all seem to have trouble with silicon based photography, if you follow the discussions.
     
    A 35mm might still be OK on the A7R II, since it doesn't have an AA filter, so the filter stack is thinner. The A7S II has the thicker stack, but OTOH it's resolving less and doesn't challenge the lenses as much. But any symmetrical construction under 35 is not really cutting it on digital (the WATE seems to be an exception, but it's zoom and not symmetrical). Owners of classical rangefinder glass – like Leica-M or Zeiss Biogons – had high hopes for the A7R II in particular, but got quite disappointed by anything from 28mm or wider.
     
    Sony (together with Zeiss) is obviously doing something quite right with their native lenses if you look up all the discussions about adapting some of the wider rangefinder glass from Leica or Voigtländer. Those symmetrical Biogon lenses were great (albeit very expensive) for film, but have massive problems on chips, some even on Leica's own.
    OTOH, classical retrofocus constructions are not that great either, as those of us know who are not only using their center part, but full frame. The 25mm Contax C/Y which I owned for my GH2 had to go after I got me an A7S and it showed such bad corners. Their new Batis seems to outclass it by far. The only wide I kept was the 18mm, but that one is slow (never wanted to hunt down a 21mm considering price and weight).
    It's obviously an advantage that Zeiss has been making both retrofocus (like C/Y) and symmetrical (think Contax G) wides for decades. If you look at Sonys native FE primes, theres not a single one that disappoints and the prices are quite fair! The 55mm for example (which I had for a test) is so close to an Otus, but for a fraction of the price. Canikon, watch out!
    If you like vintage glass as much as I do, go for retrofocus wides. I still own the Contax C/Y 18mm f4, a Minolta SR 21mm f2.8 and both Oly 21mm f3.5 and 24mm f2.8. But don't expect performance like the Sony FE 28mm f2.0 or the Zeiss Batis line wide open without stopping the old ones down to f8!

    nomad got a reaction from tdesws in Hello everyone! Need help at deciding what first lens to get   
    I still use the same camera next to my A7S for photography and I have a nice collection of legacy glass, mainly Minolta SR, Zeiss C/Y and some Zuiko. But unfortunately your question is a bit too broad. To help you, we'd need to know your shooting style or preferences.
    Let me describe the extremes:
     
    – are you into landscape with careful observation of weather and time of day, going to the right places and carefully framing your picture? Then it's legacy primes for sure!
     
    – or are you into fast action, like sports, kids, dance or such? Then it's modern AF glass for sure, and the speed of the A6000 supports it very well. You'd have no chance to compete with manual lenses and loose most of the best moments. If you want to shoot from a safe distance, the Sony SEL55210 (i.e. 55 to 210mm) comes to my mind. It can be found relatively cheap (I paid 200 €) and has quite nice optical quality, but it's on the slow side (meaning not very wide apertures for low light situations). If you like to go wider, anything visibly better than your kit lens (which admittedly is not great) won't come cheap. The 10 to 18mm comes to my mind, but since that works to some degree even on a full frame A7, it is expensive even in used condition.
     
    So, if you tell us a bit more about your preferences, we might be able to help you. BTW, that Revuenon is pretty much crap, it was a re-labeled lens from Japan or Eastern Germany sold by a mail order chain in Germany. There is only one decent Revuenon, but it was in 50 or 55mm. If you want legacy, look for Minolta SR, very nice glass in most cases (kind of poor man's Leica, they had a close co-operation in that period), and since it doesn't fit Canons it's still relatively cheap even in these times, where the Sony mirrorless cameras are heating the market. I recently checked my current lens values by averaging Ebay sales and boy, was that a good investment over the last five years (not even talking about some from my deceased uncle). Beating all stocks which aren't pure gambling!

    The 10-18mm has very soft corners on FF, even where it covers.
     
    From vintage I second the 17mm Tokina RMC (my sample is quite a bit better than the Tamron), it's low in contrast, but resolution is quite good when stopped down.
     
    For 21mm it's the Minolta 2.8 or the Olympus 21mm 3.5. Both are gems, the Oly is lighter and more compact, but can show some strange flare at some angles.
