Hello,

 

I have recently purchased an a7R and a 24-70mm FE Lens, and have been wanting to take some photos using the auto-bracketing feature to make HDR images. 

 

My issue is that holding down the shutter while all the images are taken is known to cause camera shake. I have been looking around various websites but there's nothing too clear about it. 

 

I have seen there is a Sony RMTDSLR2 Wireless Remote available, but I am uncertain of whether this will do what I am looking for, and if it does, I have seen elsewhere that you have to point it right in front of the camera (not from behind it) to take photos. 

 

There is also an iOS app with added hardware called Triggertrap but that looks quite complicated and again I don't know if that will do what I'm looking for.

 

Just looking for a simple way to take HDR photos on the a7R without the camera shaking while I hold down the shutter button. 

 

Thank you

 

Stephen

This seems backwards to me ... this phrase especially:

 

"holding down the shutter while all the images are taken is known to cause camera shake."

 

Cuz hi speed continuous shooting is a good way to assure sharp images, but only

the frames after the 1st frame cuz it can suffer from pushing the button down.

The problem of camera shake with SONY A mount becomes more serious,  when using the long telephoto lenses. This issue gets further amplified when doing continuous shooting of moving subjects like in wildlife (esp. Birds in flight) and sports. I realized this when I tested the Sony A mount in  continuous shooting of birds in flight.

 

I  found that in most occasions,  from 3rd image onwards, the series of images coming out of the camera is not sharp.  This point was highlighted in one of the internet articles by a pro photographer, who said that his/her rate of "in focus shots" to "total shots taken" of a sport event was 50% with a  Sony, whilst Nikon and Canon gave around 90%. 

 

Sony and Nikon uses the same processor but Nikon's keep on producing series of sharp images from much worse AF systems than what we get from Sony. When you get a sharp image with a Sony-believe me it is sharper than any other, but, generally on a percentage, Nikon and Canon, wins the race.

 

I believe the problem lies when the camera sensor has to do too many things with Sony and it fails. I believe that this is the reason why even SONY's "LOCK ON AF CONTINUOUS" fails when it comes to tracking animals  who are (Like a Bird) moving unpredictably. 

 

My belief is that to start off, the camera sensor need a steady image to do a sharp focus on it by use of its processor. SONY needs a system of "in body stabilization" which has to work first and stabilize the image and then use its superior AF system for focus on the subject. I believe that if Sony engineers can figure a method to do this, then world of Photography will say bye to Canon and Nikon, at least when it comes to photography of Sports and Wild life.

Lower hit ratio, but still successful, at 50%. And you say

that Sony's 50% is sharper than Nikon's 90%, and you

suspect the processor of being overworked. Processor

issue or not, sounds like quality instead of quantity, the

deal I prefer and perhaps Sony also prefers, or caters to

those users with that preference. IOW, maybe it's not an

overworked processor, just a different algoriddm. There's

no competition, no winners/losers, in that scenario, just

a difference, a matter of choice. With no competition it

follows that the issue will not be pursued in the manner

you suggest, but will simply gradually yield to the usual

inexorable pursuit of improvements of the "because we

can - and we can convince users they need it"[u/] variety.

 

Proof ? or at least a supporting argument ? Well, nobody

really needed stabilization or tracking before it became

available, and the earliest versions were sold as state

of the art to users who'd become convinced of a need for

these technologies which were far more crudely primitive

than the technology about which you are currently griping.

 

Tracking will NEVER track anything truly unpredictable, as

tracking IS predicting. The success of AF tracking depends

on the robofocus noticing and analyzing predictable small

patterns of behavior. It used to be the user's job to do that,

but users depended upon more information, and "larger"

information, than the AF tracking can access. The camera

brain only knows what it sees, and deals with information

of a "smaller" more detailed type. It knows nothing of the

rules and strategies of sports, or the behavior of wildlife,

which is the "larger" information that the user is expected

to provide.

 

Acoarst none of the above addresses the HDR situation. For

reducing shake while bracketing for HDR raise the ISO. The

HDR process greatly reduces noise, similar to the multiframe

noise reduction feature built into some Sony cameras. If the

working contexts allows, use ISO bracketing so that not all

your collected exposures are subject to a noise increase.

    • From my records, Minolta made about 8500 85mm F 1.7 lenses bearing the MD badge. The MC-X version was slightly double that. So these are not that rare. I just saw an ad for a Limited Rare MD 45mm F2 lens ( Minolta made over a million of these) so the word rare is often used in a bizarre way. Seeing that the OP has a MD ROKKOR-X version and that he appears to have bought it from Europe is kind of unusual since the ROKKOR-X versions were to be sold exclusively in America. So in Europe, this lens naming was rare.  I think the confusion about a reworked version may come from the fact that during the MC-X era (1972-76), Minolta made numerous changes to their lens line-up. First they changed the lens Mount Index dot which was initially painted like their previous series of lenses but after about 1 year, they replaced this with a slightly larger diameter plastic bead. This change happened around the introduction of the X-1, XM, XK bodies. Then they removed the small Stop Down Levers that were on most lenses up to now around 1975 since their SR T and XK/XE bodies were now boasting a Stop down mechanism. Then a little later Minolta even removed the lens formula (in this case PG) designation from the lens markings. This may have caused people to believe there was some kind of modification to the lens when it was only a marking  change. Also around 1973-74 they decided to provide a different marking for lenses sold in America ( at least USA and Canada) to identify lenses sold on the grey market that was often cause for confusion with consumers buying a great deal they could not get repaired under warranty. Same applies to Bodies starting in the same era where  X-1 was for Asian market, XK for American market and X-M for rest of the world, then SR T 102 in America, SR T Super in Asia and SR T 303 in rest of the world. So you could find all of the following with their respective front markings: - MC-II: MC ROKKOR-PG 1:1.7 f=85mm ( with SDL) This type has the hills and valleys metal focusing ring -MC-X: MC ROKKOR-PG 1:1.7 f=85mm ( with SDL and Painted Lens mount index changed around 1973-74) -MC-X: MC ROKKOR-PG 1:1.7 f=85mm ( with SDL and Plastic Bead Lens mount index changed around 1973-74) -MC-X: MC ROKKOR-PG 1:1.7 f=85mm ( with No SDL and Plastic Bead Lens mount index ) -MC-X: MC ROKKOR 1:1.7 f=85mm ( with No SDL and Plastic Bead Lens mount index and no more PG lens formula index) -MC-X: MC ROKKOR-X PG 1:1.7 f=85mm ( with SDL and Plastic Bead Lens mount index, Orange colored ROKKOR-X marking for the American market) -MC-X: MC ROKKOR-X PG 1:1.7 f=85mm ( with No SDL and Plastic Bead Lens mount index, Orange colored ROKKOR-X ) -MC-X: MC ROKKOR 1:1.7 f=85mm ( with No SDL and Plastic Bead Lens mount index and no more PG lens formula index, Orange colored ROKKOR-X) -MD-II: MD ROKKOR 85mm 1:1.7 ø55mm -MD-II: MD ROKKOR-X 85mm 1:1.7 ø55mm (Orange colored ROKKOR-X again for the American market) -MD-II: MD ROKKOR-X 85mm 1:1.7 ø55mm (White colored ROKKOR-X ( iguess orange paint was getting too expensive) ) It was then replaced with the MD-II MD ROKKOR (X) 85mm F 2 There was no MD-I version of this lens and the same with a few lenses with large apertures ( 35mm F 1.8, 58mm F 1.2, 300mm F 4.5) since they had issues with the speed of the aperture mechanisms closing down for what was  a last minute check on XD/XD-7 and XD-11 bodies requiring stopping the lens down just prior to the shutter opening to ensure accurate exposure. Some late MC-X lenses may have had the modified aperture mechanism causing the confusion that there was an updated version but the optical formula seems to indicate there was no change.

    • It could probably be used directly on the A7R ( or any other body using the Sony MIS shoe) in manual mode provided it can be positioned properly in spite of the zillion contacts Sony placed on these bodies at the front of the shoe which may prevent the shoe from making proper contact at the center. If proper central contact is not achieved, using a ADP-MAA adapter topped by a Minolta FS-1100 will do the trick. Tried it with older flashes like 360PX and a few others and it works. The issue with using it in Manual Mode is that due to the very short distances involved, calculating the proper aperture for correct exposure is a challenge. Add to this that the assist lights will not operate the way they were designed if at all.
    • I've found some great lenses that way too -- like a Tokina 24-200mm AF zoom on a Maxxum 5 for $20.  I sold the camera for $40 and kept the lens.
