Sony E and FE lenses
« on: May 02, 2015, 05:10:09 AM »
I have just purchased a used Sony A7 and an LA-EA4 adapter, letting me use my existing Minolta and Sony A mount lenses. I did not purchase any E or FE lenses.

While doing the research on the A7 vs the A7II I began to realize that the E mount lenses are for APS-C sensor cameras and the FE lenses are for full frame, but can be used on Nex or A6000/A5000 cameras. This may seem obvious to most of you but I totally missed the APS-C vs Full frame connection! Why would Sony not have called their E lenses Edt and the FE lenses EF, thereby keeping the naming conventions of the A mount line and the E mount similar?

Another thing I discovered was that the LA-EA1 and 2 have been discontinued. You can only buy the LA-EA3 and 4. What are the differences between the 3 and 4? I know the 4 turns my A7 into a SLT, like the A99 but what does the 3 do? I think it does the same but for APS-C cameras. Am I correct or have I missed something again?

Congratulation Ascot. I am waiting to see your report about difference between a99 and a7 & LA4.

LA1 & LA2 were made to use the A mount DT lens and A mount full frame lens on a mirroless body. Since some people complain that the area they were getting especially with LA2 was less than a full frame camera they introduced the LA3 & LA4 and fast lens like 85mm f1.4 or  135mm f1.8 lens

LA3 & LA4 replaced the LA1 & LA2 but both are full frame cover area compatible.

Personally i have a used LA1 and I am happy. I don't need phase detect AF. May be a new adapter with AF module of a77II will make my interest to try one.

In one week a friend of mine will get LA4 and a7II and he is willing to give me the package for a test :)

Interesting information from you both.

I look forward to hearing of your experiences with the a7 plus adapter and the Minolta glass Charles (Ascot) and also yours Rex with the a7ii. I'm very interested in the a7ii with 'Alpha' glass + adapter and what needs to be done,  settings wise, to get the best from them.

Thanks REX and Frank. I won't receive the A7 for at least a week and I'm a bit apprehensive as this is the first used camera I have bought. I have found that I most often use the A850 over the A77, so guess I prefer full frame. I never use my A700 now. I am very happy with my Minolta Glass and my Sony glass is good to very good. The 16-80 ZA is my only APS-C lens and it can be used on the A7 with three interesting options, Off, Auto and On. I think it will have a permanent place on my A77. My best lenses are the Minolta 200mm f2.8, 300mm f4 and my most used Minolta 100mm f2.8 Macro D. There is nothing in the FE mount range that can compare without spending a small fortune, assuming they become available. There should be a few new FE lenses released this year, but I am not really interested.

I looked at the A7II and noted that the main changes are:
1) 5-axis image stabilization system (Would be very nice)
2) Faster AF system (30%) (I am not an action Photographer)
3) Better video shooting capacity (I don't shoot Video)
4) More rugged full metal body (I do not see this as a problem, the A7 has a Sealed alloy and composite body)
5) Increased size to accommodate the 5 Axis stabilization (Reduces some of the advantages of the small A7 series)

So a used A7 vs a used A7II is about $800 - $1000 CAD in difference. I cannot justify that much for 5-axis IS.

LA-E4 uses the AF module from the A57 including phase detection. It also allows you to use the center spot at large apertures with certain lenses like you can on the A57, but can't with the LA-E1/2/3.

Lots of people are upset that Sony isn't expanding it's range of FE lenses faster and to an extent they have a valid point. IF there were 20-30 lenses available at multiple price points and apertures, as well as prime and zoom formats, that criticism would be quickly quelled.
There are people who actually think LENS stabilization is better than sensor shifting!

I received my A7 or (ILCE7 what a name) with an LA-EA4 adapter. It came with two 3rd party counterfeit batteries! nothing else. No original Sony battery, AC Adapter, Micro USB cable, shoulder strap, flash shoe cover, manual nor Sony box. I needed some way to charge the batteries as one was flat and the other had only 15% in it. Therefore I had to go out and purchase a Sony charger. Five hours later I turned on the A7 and realized I needed a Micro USB cable to install the latest firmware (It came with version 1.02). I did get a refund.

The camera works great with the LA-EA4 and uses all my Minolta and Sony F.F. lenses and my one Zeiss 16-80 APS-C lens in auto focus. The website at http://tools.science.si/index.php proved it had 2020 shots on it. Image Quality seems good although it's very hard to compare with my other cameras without doing a lot of pixel peeping. I think I miss the image stabilization most, must try for a FE lens to see how it works. The tiny little camera stuck on the end of a Minolta 300mm f4 white lens looks dumb, I hate to think what it would look like on a 600mm.

Ascot i didnt have any chance until now to try any Translucent adapter so i can not comment but i think the a6000 and now a7II with the on sensor PDAF are very fast with there E-mount lens. I don't know also how the tiny  E-mount Camera looks on big heavy lens. I should try and report :)

The A7 also has on sensor PDAF, but it only works when using an FE lens. Also the A7 does not have image stabilizing unless you use a Stabilized FE lens. I am finding that the lack of ibis is a major problem for me, so also is the very complex menu system forced on Sony by the lack of space to put dedicated buttons. The camera is just too small.

After CHOLLY asked for pictures with big lens i did an autofocus speed test test with a7II & 300G vs a6000 & 300G.

With teleconverter neither will auto focus and neither will show f stop :(

I discover something i cant explain. Both Camera with LA1 adapter work with contrast sensors they need the same time about  5 sec to focus from close up to target and from infinity to target  with Zone.If you release the shutter button and depress it again were the focus was locked the a7II goes again back to close up and goes all the way up slowly to find target again but a6000 continues from were has locked focus and this is in almost half the time that the a7II need In about 2,5 seconds.

Why a6000 is faster and don't need to search again from close up to infinity to lock focus? Is it because LA1 is dedicate for APS-C sensors?

Thanks for posting those shots Rex. :)

Is the shot of the A7ii with a vertical grip?

All I can say is the LA1 and LA2 are for APS-C so that may be the reason. LA3 and LA4 are for full frame and may work differently.
