Lenses / Re: Canon 50mm f/1.4 USM focus problem...
« on: December 06, 2013, 12:32:04 PM »
I had 2 of these lenses.
One I purchased used with a small scratch on the front element.  It always AF'd pretty near perfectly, no matter what body I used it on or what distance the subject.  I used this lens a lot on my 5d2, 40d and other crop bodies.  It was a great lens and I was happy with the results for years of use.
I also got a new one for a good deal, kept it as a backup.  Never took it out of the box, the warranty expired years ago.
Went to use it recently, only to find that it's AF is useless.  The thing misses focus really bad at various distances, tho sometimes it focuses just fine...  Did a little experimenting and what I found was that it would nail focus at certain distances but miss (mostly backfocus) at various distances in between.  It was repeatable enough that it seems to me to be a flaw within the lens and possibly how it communicates with the camera's AF system.
It's so bad that it backfocuses by about 2 feet on a simple high contrast target that's 10 feet away.
Seems Canon's quality control slipped on some versions of this lens.  Too bad, it provided a decent IQ/$ ratio.
Not sure I want to spend $ on sending it in for a possible repair.  Might consider doing my own take-apart and inspection.

Anyone have a similarly (mis)behaving 50/1.4 and any success with fixing it?

make sure to post some..
I'm sure to; I seem to have more fun pushing limited gear some days than using the higher end stuff.
Tho I suspect I'll be itching for one of the X-trans sensor'd Fujis in short order vs the Bayer-array bottom-end X-A1 I'm starting with.

Some things I'm struggling with, some not so much. Either way, I think the decision was the right one for me (for now).

good move
I bet you'll likely buy another Fuji before another Canon. ;)

Monday added LR 5 for best deal I could find on the N side of the border and for under $100 I have a basket of lens adapters coming via eBay to use on my new Fuji.
If that's as much fun as I expect I might drop near $300 for the nikon to fuji tilt-shift adapter.  No need to wait/pay for the Canon version for the close-up/macro work I want to try with it.  I guess I could also build up a little bellows adapter too for ultimate lens control.
I suspect I'm gonna be spending more time crawling around the farm/yard this summer with a tiny & capable APSC macro rig.

I've been angling to get an X-mount into my kit to play with and ordered a super deal on a basic X-A1 with 16-50mm kit lens on Thursday for a bit under $500.  The lens isn't great so could sell it and have a really good, APSC imaging engine with a very short flange distance for under $300.

The exciting part comes when you head over to eBay and find adapters to allow darn near any kind of lens mount to be adapted to the Fuji X to use in manual mode. There's even tilt-and-shift adapters! YAY!!  55mm & 105mm Nikon macro lens now with added T&S capability on a crop sensor.

I think I'll have a lot of fun with this thing and the pile of various (Nikon, Pentax, Olympus, Canon, M42, T-mount, etc) glass I already have.

I don't much care for the ergonomics on this little camera but it won't matter since it'll likely live on a tripod most of the time and the tilt display and WiFi may be useful.

If I enjoy the Fuji way of doing things then an X-E2 or whatever the new X-pro gets updated to might be on the get list next year.  Hopefully by then there'll also be better support for the X-trans demosaicing than there is now, which is another reason, other than being really cheap, I went with the Bayer-filtered sensor in the A-1 for now.

I think the APSC X-mount is more of an operational sweet-spot than a MFT body. If only Pentax had made a versatile, short register body instead of the K-01...  :-\

It might be the best interchangable lens sigural cam  yet made, but if you need a ts-e, or want an f2.8 uwa, who ya gonna call?

Sigma?
Samyang?
Tamron?
Olympus?
Leica?
The big Z?..

I will buy a Samyang 24mm TS in 2014, F-mount tho, it's more versatile if I want to attach it to other things.

I think the MFT gang is still in line for a lot more glass goodies to come.

And for usability, I was playing with a Fuji X-E2 last nite.  TOTALLY usable EVF.  Ergonomics are typical rectangular box but Oly's EM1 has shown what's possible for ergos.  Even the now "old" Fuji X Pro-1 has an excellent hybrid/EVF.  If they tweak that one upward in some ways it'll be a very compelling body.

I think the EVIL MILC is upon us now.  They still can't quite compete in some aspects with traditional flapping mirror boxes, but for most work, they're already close enough.  I didn't get to try it in very low light but supposedly the X-E2 can gain-up enough to see better in the dark with the EVF than using an optical VF on an SLR...

Which adapter do you use? coz if it isn't expensive, I'd like to get one just to try it out sometime.
I went cheap, not knowing how well it'd work, and just got some sturdy plated brass ones from an asian source on eBay.
The listing said they were sized to allow infinity focus. I got a couple different types to try, they're all pretty close in thickness on my caliper. With the manual Nikon lenses and close to moderate distances they work well enough for the few $ they cost me.  The bayonets fit just fine, no slop.  About all I use the adapter for now is to allow old IR-capable lenses to be used on my IR converted 50D since none of my contemporary EF glass worked very well in the IR range.
The ones I got cost less than $30, delivered. I avoided the AF confirm chip option some have as it wasn't something I needed for live view focusing anyway.

I've used some old manual Nikon glass on my Canon's just fine.
Good to future proof your investment..  you know, for when you're ready to move up. ;)

I don't really give DXO the time of day anymore. There are far more useful benchmarks for camera equipment out there that provide more useful insight. DPR, PhotoZone, TDP, etc. are vastly superior resources.

About all I find useful of their lens tests is simply comparing the results of lenses tested on the same body, using the field measurement results so you can see the relative contrast plotted as varying colors.  In this way you can get a feel of how a given lens they tested MIGHT perform, relative to itself or sometimes others, at different apertures and-or focal lengths.

Third Party Manufacturers / Re: Anyone try the Olympus OM-D E-M1?
« on: November 19, 2013, 01:24:27 AM »
I still have my E-510 and lenses. Those lenses are superior to any of the micro four thirds lenses and just need an adaptor to work on a micro four thirds body... The 50-200F2.8-3.5 lens was certainly L glass quality... who knows what will happen in the future... they might see action again :)

I haven't had time to read much yet but so far that seems the consensus; the older 4/3 lenses are better, likely because of longer registration distance reducing distortion and other optical compromises in the MFT geometry. Apparently Oly's (old) zooms are very good performers and some of those older lenses can be had pretty cheap as people moved to other systems.

Rumor somewhere I read today has Olympus putting out an "entry level" body in early 2014 that will be a bit like the E-M5, with some tweaks.  I hope this new body retains the shape and feel of the EM1.

Currently the EM5 is selling for less than $600, a pretty big price cut and tempting too, if I hadn't already experienced the siren-call of the EM5.

Muddying my decision, Fuji XM1 and XA1 are fairly economical APSC size sensors in lightweight bodies with similarly short registration distance and there's a good selection of (cheap) X-mount adapters to allow virtually any other lens to attach and use in manual mode.  MUCH cheaper option than Sony's new FF A7r.
Kitted with the 16-50mm OIS lens, essentially for free, this makes for an economical and versatile still imaging tool also and a viable walk-around street-shooter with the cheap kit lens.

EOS Bodies - For Stills / Re: Any reason to choose a 7D over a 70D?
« on: November 15, 2013, 01:30:35 PM »
Will it matter if you shoot in raw?

from the limited tests I've done, I'd choose the 70D's raw files over the 7D's.
Get the 7D if you NEED the extra speed, buffer, built quality, weather-resistance and control layout
Else the 70D is perfectly capable.

Once again, evolutionary improvements on an already good Nikon consumer series body leave competitors behind in many metrics.. and price.

One of these is on my xmas list.  2 more if it performs really well.

They seem to have changed the grip to body spacing a little from previous models, I hope it's still comfortable to hold like the 5100/5200. 
WiFi and GPS abilities, + 1080P at 60fps will be features useful to some.

How exactly do DxO mark arrive at that headline lens "score"? an average of lens performance across focal lengths/apertures? wide open? stopped down?
As JRista explained, DxOmark appears to have a Nikon bias on lens tests - BUT, that's because, for whatever their reasoning, part of their lens test also included a measurement that takes into account the signal to noise ratio of the camera body it's being tested on.  Possibly for consideration of final noise quality in printing.
The innately lower noise Nikon bodies thus boost Nikon lens scores.

@jrista, unfortunately I can't offer any advice on astro gear, that's out of my league.  I just admire some of the work others have done in this area.
We have dark-sky-preservation areas in my part of the country but I haven't taken advantage of any of them.  We also have about 3000 more feet of thick atmosphere to contend with. I was momentarily motivated to try when, after shooting some handheld dark sky shots my my d800 and 14-24, I could actually see the potential.  I only took a few tripod based shots, very quickly in -20 degree weather, so I could finally see what this sort of shooting could be like.  It's something I'd have to put some thought and effort into to make it worthwhile and I'm thinking I just might do so this winter... If we can ever get any clear skies and tolerable temperatures.

« on: November 14, 2013, 01:54:25 AM »
I see that it's performance levels are impressive and I've been intrigued by MFT for a while.  I'd have to see what the available lenses are like, some seem to have a lot of native distortion before in-camera correction.

I played with one in the store tonite and WOW!  I LIKE IT!  Feels like it was custom made for my hand, yet nice and compact, unlike my very comfortable but mugh larger crop and FF DSLR bodies.

AF was super fast under indoor lighting.  Not what I've come to expect from mirrorless, much more like newer DSLR and PDAF.

I'm definitely going to have to spend some time playing with one.
At base (200) ISO the files look, pixel-per-pixel, pretty close to the d800 output at 200 ISO.
Hmmmm...  The Fujis are really nice but methinks I small new Oly toy is now higher on my lust-list.
