LA-EA4 + something = fast autofocus zoom

Recommended Posts

Advertisement (gone after registration)

All,

 

I've tried the Sony 80-200 FE on my a6000, but I need something longer for airshow/aviation photography (hence the fast autofocus). Also the price tag for that lens is a bit steep for what you get. I'm wondering if the solution is an LA-EA4 adapter and some other 3rd party lens. Any suggestions?

 

Thanks!

I have had good luck with the Tamron 70-300 with the LA-EA4. Seems to work pretty well with the A6000. I just bought the Sony 70-400 and it works great on the A7II with the adapter but it drained my wallet..

The LA-EA4 is good enough, but i don't think anything will beat native lenses when it comes to focus speed. In addition to that, the adapter only has 15 focus points, and tracking might not work well (i haven't tested it much). Are you sure you need autofocus, though? The subject distance is proably pretty close to infinity most of the time, and if you're shooting in daylight you can probably stop the lens down and use the hyperfocal distance (or zone focusing) so that you can pretty much ignore the focus and shoot as much as you'd like..

I've got a pair of Tokina 400mm's that have worked well. One is MD mount manual focus, the other A mount auto focus. Both are optically ok, but not super, and the price is right. Here's a link to reviews http://www.dyxum.com/lenses/Tokina-400mm-F5.6-SD-AT-X-400-AF_lens196.html It rates better than the equivalent Sigmas. The MF lens looks very similar, but lacks autofocus and autoaperture controls. The copies I have are pretty sharp, good color and the build is all metal solid.

 

With the AF and LA-EA4 focus is quick. I also use it with a 1.4 teleconverter for net 560mm. The MF uses a cheap adapter and works well with peaking and magnification as long as the focus point doesn't change dramatically and quickly. I also use that with an old Vivitar macro focusing 2x teleconverter for 800mm that will also do bugs and flowers.

Sounds hyper-reasonable. Any suggestions for native, greater than 200mm, and not crazy expensive?

I have a 500mm minolta md reflex lens, but i can't really recommend it. Also used a Sigma 100-500mm (for Canon), that was pretty fun, you could even get it for Sony A and use it on the LA-EA4.

    • Madafied, Are you certain the lack of sharpness is due to a focussing issue? Due to the high resolution, your A7RIV is quite a lot more demanding than your other cameras. There are some aspects that might cause unsharp photos that your other cameras are less picky about. You should adjust your habits to get the most out of the A7RIV's high-res sensor:  - Subject motion blur (use faster shutter speed)  - Camera motion blur (use faster shutter speed or tripod)  - Lens unsharpne
    • I bought a A7RIV a few months ago and I've gone out several times to go shoot. The first photo shoot (portraits) I had with it, the focus looked spot on in camera but wasn't in focus once I got it on the computer. I thought it might have been the lens I was renting so went out to shoot some landscape shots with one of my trusted lenses. The focus looked great in camera but off when I put it on the computer. I immediately took it back and exchanged the camera. I shot again with the newly exchange
    • Hi Gang, is there a guide somewhere to which of the older minolta lenses and sgma/tamron lenses as well, i need a long lens for birds mainly around 400mm or more and have seen loads of cheap long lenses on ebay, some are minolta some sigma etc, question is which will work ok with my A7ii dslr thanks

    • I have never done any astrophotography. It is my understanding that with the a7Riiiii raw uncompressed, the only change that happens by selecting a picture profile are the gamma settings. https://youtu.be/9GGDkf4wMWg Therefore, which picture profile, if any, is best for astrophotography? Thanks very much for your help.
