Your issue makes no sense to me? I have owned the Sony 7RII for a couple years and use nothing but Canon glass with a Metabones adapter. It has always produced excellent sharp images with stunning color rendition. I just wish I could justify the extreme cost of the 70-200 f/2.8G, despite the reviews I have read that the image quality does not compare favorably with same Canon and Nikon lens at nearly $1k more. I will be renting one soon, so I may compare for myself.


It is the lenses if I had to bet. Earlier copies had these issues, the op bought both zooms used.

I do see the spots on the sky. I didn't until you mentioned them but I do now. Bummer as I just paid a professional camera repair store in Denver, CO to clean the sensor about 50 shots ago.

I bought both of these lenses used, one from a fellow here on UHH and the other from KEH Camera. So I have no idea how old they are. Also I'm not really sure but I believe the 16-35mm f4 lens was used to shoot that photo. Though I get similar results with either lens.

Thanks much.


Take it back and show them this picture. They have to fix it. While there, go to a camera store, if this store isn’t one of them. Take yo camera and your zooms with you, and ask the camera store to let you take identical photos with new copies they have in stock vs your zooms. Go home and compare.

Like I mentioned earlier in this thread, both zooms had this issue, when first introduced and there were lots of very unhappy customers. It wasn’t unheard of someone go through 3 or 4 copies before they would get a good copy.


Sounds like it is time to contact the manufacturer.

Not sure what Sony can do for the OP though. I keep saying that it is the lens, and if I’m right, Sony isn’t going to replace them. If it is the camera, well, it maybe a pricy repair.

Thank you Gessman !

I'm beginning to feel a bit guilty as I suspect that I might have been a bit hasty even posting about this. I strongly suspect that I have a lens problem and I thought that before I even posted. I probably should have spent more time looking into this on my own before I bothered you and other UHH members about it.

Thank you ( and everyone else ) again


Well, I wouldn't be concerned about being a "bother" about this if I were you. It hasn't been a problem for me. I type fast and unconsciously enough that a little conversation is rarely a problem. In fact, I often go back and read stuff I've said and discover that I may occasionally be even more unconscious than I originally thought and I'm sure there are others who might agree with that. Carry on and don't sweat the small stuff! I hope you get your problem sorted out soon but "micro-adjust" doesn't seem to be the answer in this case since native lens don't have to be adjusted with mirror-less Sony bodies, as has already been mentioned.

If, as others have suggested, there were problems with these lenses early on, there may have been a recall or a firmware fix. You would find out about those from the manufacturer.

To me, the entire sample image appears "soft" (I don't care what Photoshop "says").

I haven't seen anyone ask what might be the simplest question and easiest solution all...

Do you have a "protection" filter on the lens? If so, have you tried shooting without it?

Filter quality can effect every image made with it. But also some lenses just don't "play well" with filters... even very good filters. I am not familiar with your particular lenses, but... for example, the original Canon EF 100-400mm (push/pull zoom version) doesn't "like" filters. Anything on it... even the best filters made... cause it to go soft. And when that happens it's much like you are seeing... the entire image is soft.... not just one part of it (which is what's usually seen when focus is off or a lens has a de-centered element or other fault). A lot of 100-400mm lenses were stunned to learn how sharp their lens was, when they removed the "protection" filter they'd had on it from new (after all the, lens' deep hood probably does a better job of "protecting" than some thin piece of glass ever could).

Hi all,

A bit of a problem and I figure this is the place to find answers...

I own a Sony A7rii which I think is a mighty fine camera but I can't get a decent photo out of it. I might be wrong but I strongly suspect there is no problem with the camera but suspect it's a lens thing. Everything I shoot is soft. Nothing is ever well focused. Auto focus, manual focus, doesn't matter. Nothing is ever sharp.

I have the Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS lens and the Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS lens and they both take very soft photos. Neither of these are the much more expensive ' G ' models, which I"m sure are much better, but for the price of the ones I have I would have thought that I could have gotten some pretty good shots.

Could it be me, the camera or is it possible that these two lens are just never going to shoot truly sharp photos ?

Your thoughts greatly appreciated.

Thanks !

I have not seen any of the following mentioned so pardon me for any repetitions.

If you have ANY filters or other gizmo attached to your lens then take it off. I do not care how much it may have cost. I had a
$90.00 polarizer on my A6000 once and after several hours of pulling my hair out I removed it and VIOLA! focused sharp as a tack.

Try cranking your aperture up to F 14 or F 16 and shoot in aperture mode auto ISO on a calm day with a solid tripod and remote trigger.

Start taking samples at a shorter distance. If your image is sharp then work your way out incrementally until you start having focus issues. Keep in mind that 35mm is not usually meant for long distance sharpness.

Just my two cents worth. Good luck.

Hi Lille,

My suggestion may not be the complete answer but I suggest that a lot of your problem maybe yours alone. Let me explain. Your aperture selection is fine, your speed however is not, not even on a tripod often.
What I suspect is that you are getting camera shake when you press the shutter button. If you must use that shutter speed, then use a long cable release instead of pressing the shutter. Or use a wireless remote control, they are very cheap these days.
Raising the ISO might help you increase the speed as well.

All the best for future shooting,

Ron

Hi Ron,

You may be right about the shutter seed though I've always thought that as a 'general rule' when shooting a hand held shot with a DSLR one should normally not use a shutter speed that is lower than the focal length of the lens. I.E. don't use less than 1/100 of a second when using a 100mm lens or not less that 1/50 of a second with a 50mm lens. So I would assume that using a camera that does not have a mirror to slap around, mounted on a very sturdy tripod using a 2 second shutter delay and with no wind using a shutter speed that is almost TWICE the fl of the lens would be high enough. But maybe not.

Also if 1/50 is to slow and causing a blurry photo would not the entire photo be fuzzy ? ( parts of this photo is not blurred at all )

I need to go out and shoot more !!

Thank you Ron

Ah ! I'll look into that as I have not done any micro adjusting of either lens.

Thank you .


I believe the micro adjusting is only for when using A-mount lenses on the e-mount with an LA-EA adaptor. For e-mount lenses the focus sensors are on the main sensor so no adjustment is necessary or possible.
Grasping at straws here, but I think the A7Rii has an option to select between phase detection focus and contrast detection focus or both. Check you are using both, but I would expect this to reset to both by default on Setting Reset.

I thought you said it was on a tripod. Is now handheld?

And, Yeah to the filter. I had not thought of that, but a cheap filter could certainly cause that.

No protection here ! At least not on my lenses.

The only filters I've ever used are pretty high quality polarizing filters and occasionally an ND filter. The ND not so often as I still have lots to learn about them. I'm quite sure I didn't have a polarizing filter on the photo I posted.

Thanks :)

Hello Linary,

Thanks much for taking the time for me.

I'll go shoot a bit today and do as you've suggested. I"ll shoot at f8 again and use a bit higher ISO. On that photo I adjusted the exposure by using aperture mode, with f8, and adjusting the EV to 'shoot to the right'. I thought the exposure looked about right but surely a higher shutter speed can't hurt. Also the stabilization was turned off and I used a 2 second delay for the shutter. No wind and no mirror.

I do have a question for you though. If there were wind or anything else that caused some slight camera movement and therefore caused the photo to be blurry, would not the entire photo be blurry ? What might cause some of the photo would be sharp and some not ?

Thanks again

So to recap, you did use f/8, you did use a tripod, you did set a timer delay.
Your shutter speed was 1/50th sec. and whilst this should not really cause focus issues (you were using a tripod), see if you can shoot something at 1/500 sec. or faster.
Many of the comments above are very pertinent, - shoot a series from f/4 to f/16; shooting a high contrast target of some kind; If you can beg or borrow another lens to try it might confirm that your lenses are good or bad.

In answer to your question re the wind etc. Everything would be affected by gusts hitting the camera but some parts of the image more than others. If the camera moved around a pivot, then the outside pixels would travel further than the centre pixels. The outers would appear out of focus, the inners would appear to be soft.

A couple of days ago I lost sixty or so images because I had not fully tightened the locking knob on my tripod and did not notice the slow droop of the camera. Thus ended that session of time lapse. Make sure everything is locked down tightly. Tripod on solid ground, not gravel etc.

A friend of mine who has the same Sony as you - I don't know what lenses he has - told me it took a while before he got used to the camera coming from a Canon background. Several months down the line, he is now producing pin sharp images. (n.b. English pins are sharper than USA tacks )
