    Best lens I own

    I have 3 Zeiss lenses for the NEX APS-C  (12 2.8 touit, 24 1.8 and 16-70 F4) and now the 35 FE2.8 and the FE5 1.8 for my A7r. Others than that I used several older manual Zeiss lenses on the NEX-7 and experimented with some on the A7r as well. To make it short: This lens is nothing short of amazing! It's the best Zeiss lens I have used so far! All the pictures I took with this and the A7r I made wide open have such a high level of crispness, detail, colour and contrast, I don't know how a ...

    Sonnar 1.8/55: Hands-down the best portrait lens for my A6000.

    I wanted to downsize my DSLR equipment slowly but surely been building up my A6000 lens lineup. I shoot a lot of portraiture and was looking from a 'go-to' portrait lens like the much-vaunted 85/1.2LII that I have with my Canon equipment. I wanted a fast portrait lens that would come close to an 85mm ff equivalent with my A6000 so that I can do not just full-body shots but close up portraits as well. After I saw a few samples from the owners, I picked the Sonnar 1.8/55. Having picked up a ...

Image Stabilization on Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T*

I have Sony A7 and planning to buy this lens but since A7 and this lens don't have image stabilization I wonder if it's gonna be really noticable since I don't primarily use tripods in my shots. I know there is an option to buy 24-70 (FE) with OSS but all reports show this lens is mediocre in overall quality. The price for this 55 mm bites so I really need help in this matter. Thanks.

Four other ideas: (1) Test to see what shutter speed works well for you. (2) When the light is low, go ahead and use a lower shutter speed than your limit. Perhaps even much lower. Since the amount of blur is random, take 10, 20, or 50 shots when the image is important and you have to use a slow shutter speed. You may well be amazed and delighted that one or more of the images is quite sharp. I use it all of the time. (3) Find something to lean against, or put your camera on something stead (solid rock is often better than any tripod). Continue Reading

That's still just a Micro Four Thirds sensor, which is 1/4 the size of a full frame sensor. To my knowledge there is no mirrorless system with an APS-C or larger sensor that has IBIS. And I'm not just talking about the amount the sensor needs to move; I'm talking about that AND the mechanism needed to move it. A larger sensor needs more circuitry and more hardware for heat dissipation than a smaller sensor (which is also why a Panasonic camera can record 4K straight to the SD card while the A7S can't). All of that PLUS IBIS seems a bit much to ask. Continue Reading

Tips for shooting an 18 month old with the A7?

This will be my first time shooting a young child.  (doing this for a friend)  The idea is to get some portraits, so while its not going to be action shots, I reckon she won't be perfectly still either.  I'm going to start with the FE55mm, (for AF) and then maybe try my hand with manual focus on my Minolta 50mm, and Rokinon 85mm. My question is, what type of shutter speed should I be looking for?  It will be be indoors, and a well lit living room, and I'll have my reflector.  I don't have a flash or lights of any kind yet. (I do *need* a flash)  My thought was shoot in M with the lowest shutter I can get away with, the A that I want,  (2.8-5.6?) and auto ISO up to maybe 3200.  What about focusing?  Would AF-C be something to try?  I've really never used it much, I'm mainly an AF-S /center shooter.  I've played with the object tracking, but its seems to suck unless you have really good lighting.  Also maybe burst shooting?  Something else I don't play with much.  I always shoot ...

Okay, it turned out pretty good.  I mainly used AF-C, object tracking didn't work so much.  AP mode with ISO 100 outside, M mode inside with auto ISO.   Kids move toooooo much! Continue Reading

Tip 1)   Drug the kid! Tip 2) Tie them down! Actually with the 55 should be good......just put as much space as you can behind the victim. I would just shoot...try all the things you have asked about and see.     If there is somewhere nice outside, see if you can do that too. Maybe start with the 55 at f2 on in A mode with auto ISO with the upper limit set at what you find good. Have fun. Continue Reading

Feedback from a7r users

I just sendt my D600 to the IR (again) and finally decided to sell it and get a A7r when i travel to US next month. After the release of DF and 1V3, i don't see nikon making any "ar7" in near future and after reading the reviews of Sony 55FE, 70-200FE and announcement of a 16-35FE, i'm pretty sure Sony will release som stellar glass in the future for the E mount. My current gear: D600, Nikon 18-35G, Nikon 85 1.8G, Sigma 35 and a SB700. What i look for in gear: Sharpness, bokeh, weight, af, price. What i use it for: family stuff (everyday stories, fairs and so on), backpacking, traveling and landscape. I actually preorder the sigma 50mm Art and had a deal to swap my 600 for 800E, but after calculating the weight of my backpack, I had 2nd thoughts (d800e+50mm+flash = 2kg straped around my neck) vs a7r+55mm+flash which is lighter than the body alone of a d800e. Me and my family does about 50+ days of mountain hiking a year and i have been man enough to carry my gear so far, but if i ...

yes, the a7r has hss, but it also has a slow shutter, that when combined with pre-flash, has generated complaints about shots of people with their eyes closed... search this forum for the threads. the big sony f60m flash that i have will do hss with manual power settings, which eliminates the pre-flash, fwiw. you could go a7(electronic shutter) instead of a7r, to help alleviate some delay, but it won't be a step up in pq from your full-frame d600?? you want to save weight with a smaller body, but then counteract that with a heavy sigma lens and adapter. you could save weight with a cheap adapter and a light legacy prime, but no autofocus. the sony 35mm prime is xlnt, but it has serious vignetting issues, it's a dark piece of glass, but it'll save weight, and you can use the legacy approach for when you need to shoot in a low-light situation. tough call... i'd be inclined to learn how to clean the d600 sensor myself, and live with it for awhile.

I bought the 18-35G in hope to not drag along the sigma 35, but the Nikon 18-35G is so soft and flares so much that i "never" use it @35mm. So if the new Zeiss FE16-35mm F4 OSS is "sharp enough" @35 i would only need the 16-35mm and the 55mm for backpacking. We don't know the weight of the new Zeiss UWA, but i can't imagine that it's going to be heavy weighter, looking at the previous lenses for FE and the F4. The sigma 35mm would be for indoor shooting and after sundown, not around my neck during daytime backpacking. most likely been sold after a while. I also want to get rid of the AA filter which is in both the A7 and D600. I initially bought the D600 so that my wife and kids could use it with all the "modes" and the popup flash, neither of those things has been fulfilled, so been waiting for a used D800E from my local photo store for a couple of months now. If i knew that Nikon would produce a FF mirrorless camera in near future i would stick to my D600. Been reading a lot of ... Continue Reading

- The 55FE is the second sharpest lens tested by DXO with the Otus being first. I see no reason to go with the Sigma instead for a normal prime. - Shutter shake I haven't experienced or can't notice. A lot of the Canon convert users with heavier lenses seem to be having the problem but there are workarounds paying attention to shutter speed. There is a drawback with the A7 and A7R and the preferred 1/60th shutter speed for Aperture priority or Program Auto. It is too slow for full frame and Sony should provide a menu option to adjust this to a higher preferred shutter speed. The workaround is to use Manual mode and auto ISO limited to 3200. It works very well. - HSS works for me with the Sony HVL-60M resulting in use up to max 1/8000th shutter speed but I don't know if your Nikon flash will. You could bundle the Sony flash and get it for $100. - You will likely get worse AF speed compared to your D600 for AF since PDAF is not available with the A7R. However, I am thoroughly ...
