I take that the LA-EA4 has been properly microadjusted for the lens? LA-EA4 is DSLR-type pure-PDAF and if it tends to backfocus a lot the cure may be in microadjustment. Native E Mount lenses obviously do not need this when CDAF is used...Gotta admit, that picture blows if you look at it closely. It is a pretty small crop. That sign about 50ft in the background seems to be more in focus than Rihanna. Do you have a lot of pictures like this? Is the micro-adjust set for the lens? Is electronic first curtain on? Do you have any lenses that work on the A7 under these conditions?[ATTACH alt="Screen shot of Exif Info. said:531602[/ATTACH]

Sony Where are the Sharp Telelphoto Lenses for Sony A7!!!!

I doubt that totally.
However, let's take your point as fact in order to prove my point. FF lenses are more pricey than their cropped counterparts, by at least a factor of two. If, as you say, FF lenses are less demanding, that would mean the profit Sony makes on these lenses would be quite high. Why on EARTH would they be reluctant to put more of these cash-cows out on the market?
It's worth the wait, even if it is F4.0.
As I said, I had already pre-ordered the lens, and was just scoping some other large retailers and was surprised to get lucky. I noticed it was "back ordered" a few hours after I placed my order. I may have gotten the last one that wasn't already paid for.
I really expect it to be broadly available real soon. The Sony store shows mid-May. I bet it's sooner than that. If you are in a real hurry, there's always eBay. There are some reputable Japanese sellers that have that lens for USA retail price (incl. shipping). But then, it's gray market.

Thank you for the heads up..I may just order from Japan.
I make a living as a photographer, so it is Crucial to produce top notch images!.
mid may, may not seem far, but in the photo world, thats along time to wait.
I know just how you feel. I came real close to doing the Japan eBay route. There are possible pitfalls with gray market, but I've never had to return a lens for service.
It can be a bit maddening. When they say "mid-May", that could mean mid-May. Or it could mean June something. But then, it could be in most stores in a day or two. I still have no clue why Samy's got a bunch to sell, but so far none of the NY photo sources are shipping this lens.

In your initial post you wrote:
"Hurry uuuuuuuuuuuup and bring out a telephoto lens...and, "NO" I dont want to use the LA-EA Adaptor....they render blurry soft images,, unless im using a F1.4!...urggh."
I can understand that you want the lens - now!
But from a professional photographer's point of view I don't understand why you are buying into a completely new system with a few lenses, expecting and relying on this system to fullfill your needs without knowing much about issues like tacking AF performance, refusing to use the LA-EA adaptor (claiming that the mirror is softening your image, which is not true for Sony SLT cameras), and then blaming Sony for not having YOUR lens available!
Not vey professional in my opinion!

Professionalism has nothing to do with what i "feel" sony should have, or what i need "now"
to get the job done.
I am not here to impress anyone, i could care less...just sharing "my" experiences.
I'm not here to win some Popularity ribbon award.
Some of ya"ll act like you own Sony itself,,ha ha ha, and expect "no one say anything bad about
a manufacturers product.
I happen to like sony alot, because if i didn't, i wouldn't have previously owned:
A900, A77, A55, Nex 7, RX1 Zeiss 24mm 1.8, Zeiss 24-70, 135mm F1.8, 70-200mm 2.8 (which i wish never sold)
and now the A7, and future A6000/a7s.
not bragging or anything, but I have also owned Nikon and Canon Full System..each one has its strengths and weaknesses.
I've owned Leica, Panasonic, Olympus, Pentax, etc etc...its all apples and oranges.
I love photography, and by the grace of god, i am fortunate enough to at times to have been able to afford different systems.. no big deal.
I love sony future vision,and love how they made the first smallest full frame lightweight digital body (my 5 year dream) but do wish they would do what no one has ever done, which is
introduce a new system (A7) with a fast 2 lens line up at the "SAME TIME".
its not impossible.
maybe its time for a new LA EA5 that mimicks the same AF system that the A7/A7r/A7s & Nex A6000 Has, and not revert to pass technology...just sayin.

Wow! Why the need to defend your 'love affair' with Sony?
I just pointed out that buying a brand new system before the needed lenses are available and then rely on this new system for professional use (no matter which brand) seems ... unprofessional.
For my bussiness I use a system that I know, and which fullfills the needs of my clients. I do not swich between brands. Too much wasted money, and not so healthy for the bottom line for my bussiness. Also, the bread & butter equipment has to be at hand, tested out before doing paid work.
That's my take.

False. The first mirrorless µ4/3 was announced in 2008, the first Sony APS-C mirrorless in 2010.
There's also been 2 larger brands pushing those lenses out versus mostly Sony on the E mount side.

The NEX3/5 launched in may of 2010, the G1 in Sept 2008. Sony has had 47 months, MFT has had 67 months. No it's not identical but not the biggest chasm either, they are relatively close.
Very true, but that happens to be one of the strengths of the system. It's literally reversed, Sony is spread thin, MFT is overlapping with many brands. Kodak is now in it too, and who knows who is next. Even Sony themselves had made a MFT NEX concept at one point.

Yes, 43% longer is "relatively close" or "as long" in the MaxISO universe, no doubt. ;-)
Where can we see this concept from Sony? I think you're confused with the APS-C concepts.
The point is, if you have the reason above, "for some reason" is needlessly modest.

Picture 1: NEX-6 + EA2 + Minolta 200/2.8No exif data,,,no merit..could have been taken with any combo.
Really? This isn't an easy target, and certainly not on stroll... this one is my little flying Chihuweenie (and the DOF is only a few inches)...
And certainly not sitting...
Picture 2: Same as above except camera body was NEX-3
And all that matters isn't whether te above could or could not have been done with any camera but they were done with something you claim does not work. The first image was actually taken in fairly challenging conditions (trail thru the trees, with a small dog that is mostly black and runs like a maniacal beast). Both images were chosen for samples since they also represent some of the moee challenging AF/tracking situations.
Chances are, you haven't checked for Front/back focus either which you should before you blame the adapter.

Nope. A long tele zoom is nice to have but wider to normal lenses are always going to be a priority especially with larger sensors and in this case, FF. It is small sensor thinking that starts and ends with optical reach argument.
If you care less about sensor size, smaller the sensor, chances increase of you finding longer reach. Heck, Sony did a 24-200 equiv f/2.8 lens in one package at a third of the cost that requires a lot more in m43 world.

Actually, a list:Yeah, your all talk..but no solution.You know what else does that? Incompetent photographers.shot the A7 with LA EA4, and Minolta 50mm 1.7

- Check you lens for back/front focus before you blame your tool. In fact, your tool provides you with the convenience to correct the issue (see AF Microadjust).
- The sample you posted depicts a very poor choice of lighting. At this point, the blame on the tool is always going to be secondary.
- the tool does not "drag the shutter", the photographer does.

I don't get it! The A7/A7R are specialty cameras- not all-around shooting cameras. So why all the complaints about not being able to directly replace DSLR's?
The FE lens development chart was released at the same time as the A7/A7R, so, why all the complaints about lens shortages when we knew about them when we purchased the camera?!!!
Why did all these people purchase an A7/A7R?? I really don't get it!! For all those who are so dissatisfied with their A7/A7R;s -please sell them and go back to Canikon so you can stop all this whining nonsense! There are plenty of us who will buy them and appreciate them for what they are.
Also, a correction from this thread: I use the Sony 135 f1.8 with the LA-EA4 and it is absolutely bitingly sharp - not soft! This is more misinformation propagated from one isolated, anecdotal experience. I read of a lot more similar misinformation on these forums.
I love my A7R, but fully realize it is not an all-around camera so I keep my professional Nikon and Canon gear. For some uses this camera is nothing short of stunning - for others, it leaves a lot to be desired. Overall, it is a positive leap in technology.
Sony pushed the "design envelope" on the A7R with a 36mp continuous live-view camera in such a small body (dealing with dissipating the heat from the active sensor in this small body, alone, must have kept the engineers up at night for months). That is what the technology would allow for - today. Tomorrow will be different, but in the mean time, why don't we just appreciate what we have and not try to make it into something that it is not.

Assuming you have more than one lens for the adapter, and that this is the combo that gives you backfocus, the issue is not the adapter but mainly the photographer for not verifying that the combo works.Thats exactly my point. The adaptor has alot of my shot backfocusing.Gotta admit, that picture blows if you look at it closely. It is a pretty small crop. That sign about 50ft in the background seems to be more in focus than Rihanna. Do you have a lot of pictures like this? Is the micro-adjust set for the lens? Is electronic first curtain on? Do you have any lenses that work on the A7 under these conditions?[ATTACH alt="Screen shot of Exif Info. said:531602[/ATTACH]

A7.LA-EA4.Minolta 50mm1.7.
when i had the E Mount 18-105mm F4, that wasnt the case..with the exception of
the 55-210mm..now that lens is moody...rudy.
Front/back AF is one of the first thing I check with a new addition to my AF lens lineup if it uses mirror PDAF. For example, I recently received a few old Minolta Maxxum lenses from a fellow DPRite (for the cost of postage!) and one of them (24-50/4) backfocused on a55 as well as on EA2. With a55, I have no choice as it does not have AF Microadjust feature (every other lens works spot on). But, with EA2, I can micro adjust and did. So, the 24-50, if used on a55, will be a MF lens while on EA2 to NEX-6, it has been micro adjusted.
With focal plane AF (as in E-mount cameras), this is a non issue but a potential issue with SLRs and SLTs which EA2/4 resembles. So micro adjust to ensure your capture AF point is the same as captured.

so how will i know to adjust this, without every noticing a problem.
All the E mount lenses i used before never back focused, so this came out of no where.
Im going to have to buy a 55mm F1.8 FE, and use the in body clear image zoom to achieve
a little more telephoto zoom, until 70-200mm hits stores in the u.s.

You can find tools to test front/back focus online (usually free). Or, simply use your own set up. With a prime, it is fairly easy. Establish targets at various distances. Keep aperture wide open.
AF at a specific point on a target (let us start upclose) and capture the image (use timer/remote trigger and tripod, in good light at low ISO, to eliminate variables). See if focus is where you set it to be. If you find focus issue, you will be making adjustments (using AF Microadjust option in the camera menu). But repeat the test to confirm that the first issue was not a fluke or in error. You may want to repeat this at your other targets. Usually, a mid range target will be a good benchmark.
Now, pick one of the targets if you saw a focus issue and dial in micro adjust (for sake of seeing the effect, go to an extreme setting and work your way back, to pin point accuracy).
Once you have the number dialed in (say, -4), it will be saved in the camera for that particular lens. Now, everytime you mount that lens via the EA4 on the body, the adjustment will be used. Shoot away!
The microadjust issue is a mirror PDAF issue due to misalignment of optical paths. This is not an issue with native E-mount lens (or when using a non native lens but CDAF) since there is only one optical path that leads to the sensor and AF is performed there.
In a DSLR, however, part of light is sent to OVF, another part to metering and a third part to PDAF module (in SLTs, as would be the case with EA4 as well, the split is two parts: one to PDAF sensor, the other to the sensor).
When a DSLR grabs AF, it is using the optical path from the subject thru a secondary mirror (behind the main mirror) to the PDAF module (when using SLT PDAF, there is only one mirror which reflects part of the light to PDAF module).
Now, when you take the image, the DSLR mirrors flip, and the sensor is exposed. However, if the distance to focus module was longer or shorter than it is to the sensor, the image will result in front/back focus. Microadjustment allows for this correction (to make the distance of the light paths equal).

Because Sony write it o their site and any publicity !
Read yourself on Sony.com!
I"t's all the full-frame performance you ever wanted from a conventional DSLR, but in a compact size that will change your perspective entirely."
-
-
"DSLR-like focusing speed
Enhanced Fast Hybrid auto focus combines speedy phase-detection AF with highly accurate contrast-detection AF, which has been accelerated through a new Spatial Object Detection algorithm, to achieve among the fastest autofocusing performance of any full-frame camera. First, phase-detection AF with 117 densely placed phase-detection AF points swiftly and efficiently moves the lens to bring the subject nearly into focus. Then contrast-detection AF with wide AF coverage fine-tunes the focusing in the blink of an eye."
-
-
"Get ultra high-speed AF despite the use of a full-frame sensor via an advanced image processing engine and improved algorithms that combine and optimize image sensor read-out speed."
-
It's because it can't do anything that "you and some" declare it's a specialty camera or "landscape cameras" !
Not what was/is advertised by Sony!!
