On Nikon D810 Preview preview (1051 comments in total)

Im going to upgrade from the D800e but to be truthful, this is more of a way for nikon go get the price back to MSRP till the D900 comes out. Its a old trick, it works for cars and so also with cameras.

Anyone ever seen the Monoprice tripod. They are not huge into camera gear but they seem like they are going that direction. http://www.monoprice.com/Product?c_id=117&cp_id=11701&cs_id=1170101&p_id=10263&seq=1&format=2

On What is equivalence and why should I care? article (1743 comments in total)

Another factor when slapping a lens on a adaptor is the sensor stack (optical glass thickness) See lens rentals article on this.

Wide angle and/or fast lenses are quite sensitive to sensor stack thickness and will degrade the sharpness of a image.

Great camera crap software. If only lightroom supported it.

Mssimo: ISO 64 should be a big deal when it comes to the numbers game (DXO-Mark) This camera might be able to hit 14.5 or 15 stops of DR. In the real world, it would be the same as the current cameras from ISO 100-6400 and about the same as canon from ISO 1600+ as far as DR.

I assumed a few things..sorry. The D800 and other sony sensors show the DR gain at lower ISO's. Canon is very flat from ISO 100-1600. Pentax K5 added a lower iso and was able to gain top stop in the DR numbers race. Nikon, adding a lower ISO, might be able to gain a bit more DR. If you compare the D4 vs 1Dx, you will also notice that the DR and SNR is the same past iso 1600 or so...one reason why sport photographers are not running over to nikon.

wherearemyshorts: With no optical low-pass filter, is there a cover over the sensor?

If no cover how careful must one be to clean the sensor?

Or did I miss something?

thanks

im sure it still has a IR filter and a small amount of optical glass

iShootWideOpen: So they are saying this sensor will hide all the flaws in the mostly less than stellar Sony lenses.

How about flaws in all "modern" lens designs? This is about physics not brand names.

In reply to:

nicoboston: Great technology, but isn't the electronic correction of aberrations more rational? And, more importantly, more flexible?
I like the approach of DxO OP and others. It's more realistic IMO.

You cant correct out of focus images. If you look up field curvature, you will see how some lenses are sharp when you focus on the center or sharp when you focus on the edge but not both (assuming you are taking a pic of a brick wall) You can correct this with complex lens designs. The best of both worlds could be a curved sensor with new/simple lens design and post electronical corrections.

I have a D800e and sigma 120-300 f2.8 sport. Something I started to notice is that the bigger your gear gets, the less pictures you take.

On DxOMark recommends best lenses for the Nikon D800E article (72 comments in total)

Seems like zooms crap out at 36mp. I guess if you love zooms.....stick with the 24MP bodies even in the future. (im sure image quality will be better but no more detail)

Also, as sensor resolution goes up, the requirements for the sweet spot of the lens goes down as far as fstop. Due to diffraction, a lens performance must peak around f5.6 for a 36MP sensor and maybe around f4 for a 50MP sensor.

Anyone else noticing this "trend" in performance?

This might be why the Zeiss 55mm Otus costs so much more, They achieved performance at f1.4/f2.

On Lytro announces Illum light field camera article (346 comments in total)

What I dont like is that this company is very deceiving, or at least the marketing department is. They do not want to share how the actual technology works and make up new terms and verbiage in order to something new out of old technology.

As far as the Illum, this is a much better camera because it can actually get something out of focus, the older model had such a small sensor that you had to ram something right in front of it. The price is a bit too high for something that will be used as a toy. If one of my friends had one, I would wait a week before they got bored and then borrow it.

In related news, panasonic seems to have made a sensor that can capture a "light field" at full resolution. It places the micro lenses below the "sensor". They have a Gate layer that is shut for the first part of the exposure then it opens up and the layer below reflects light back up into the sensor.

Overall im at least a bit excited to see what actual people make from this camera.

On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (545 comments in total)
In reply to:

simpleshot: The DXO test comes out with the same result as the tests from SLR gear and Digital Picture. They all confirm that:
1. The Sigma is sharper than the Otus, except in the corners.
2. The Sigma has less vignetting than the Otus.
3. The Sigma has less distortion than the Otus.
For all of that, the Sigma only costs $950 as opposed to $4000 for the Otus.
The Sigma has AF, which makes it a lot more practical.

We already know that the sigma is a great value. The Otus will show its "horns" when the 50+MP cameras come out. It is also a cinema quality build. That alone will double the price of a lens. I have two ziess lenses and I compliment them with two sigmas (the 35 and soon 50 art)

In reply to:

joe6pack: The M43 sensor is 17.3mm x 13.0mm. Now they come up with a 21mm x 12mm. 17.3mm -> 21mm is a significant difference to me. It means many existing lens will be showing vignetting. Am I missing something here?

If this camera is gaining popularity. It could also mean that future M43 lens will be bigger to accommodate the wider sensor, covering 21mm x 13mm. That may not be such a good news for M43.

I think you are assuming they always cut it close with the image circle. As with the nikon 35mm f1.8G, lenses sometimes cast a much larger circle than needed. If its an issue, it will only be with a handful of lenses (If any).
