Testing how sharp my lenses are, on my new camera: a Sony a6000 (24 Mpix APS-C)
A summary of a very nice dynamic range test that Tony Antos recently posted on YouTube
I love the very cheap Industar 52mm f/2.8 so I bought another couple of copies for some friends. They are all so different!
I have a new camera, the very lovely and very tiny Sony RX100 IV. Let's see how good it is for stills, compared to my old NEX-5N.
Testing sharpness on a couple of small normal vintage lenses for mirrorless cameras: Industar I61 (52mm f/2.8) and Leitz Summicron-C (40mm f/2.0).
Testing sharpness with the same lenses on two camera systems: an a7S (12 Mpix full frame sensor) and a NEX-5N (16 Mpix APS-C) with SpeedBooster (which gives the APS-C camera a FoV that's about the same as in the FF camera).
I tested the Sony a7r and a7r, looking at sharpness, dynamic range, and high-ISO performance.
I made some presets to adjust exposure in slog2 footage from the a7S. I use them a lot, so I thought others might be interested too.
Testing my lenses with my new camera. Both in stills mode (4240) and downsampled to 1920x1080.
I managed to bring together a lot of very nice cameras (a7s, GH4, 5D3+RAW, pocket, BMC,etc), and put them to the test. In this second set of results I look at dynamic range. Now the pocket and the a7s are the stars of the show.
I managed to bring together a lot of very nice cameras (a7s, GH4, 5D3+RAW, pocket, BMC,etc), and put them to the test. In this first set of results I look at sharpness. Oh, my, that GH4 is sweet...
Shashcam.de is a German website that runs some really neat camera tests, I took some of their results and built a nice little table
Now I have a very lovely a7s and a very lovely suite of settings to go with it

Premiere CC now can work natively with DNG files from the Blackmagic Cinema Camera. Let's see how it looks...
Some of them need some work before they can be used with a modern fullframe camera, or, in my case, with a SpeedBooster
Some tests to see if an APS-C sensor with a MetaBones SpeedBooster really is as sharp as a full frame sensor
A night visit to the Alhambra with a Canon 5D Mark II and a Tokina 11-16mm f/2.8 (designed for APS-C, but works as a great 16mm prime on full frame too)
A picture profile for the BlackMagic Cinema Camera (just a bunch of very specific settings for importing the RAW DNG files)
A detailed look into several options for working with footage from the BlackMagic Cinema Camera
Taking pictures with the sensor from my Sony NEX-5N and some very old bellows cameras (from 1910 and 1917)
Given my lens set, will my images be sharper if I move from APS-C to full frame? I try to find out, empirically
A new set of tests, this time with a full frame camera (a Canon 5D2)

A torture test for the Canon 550D (T2i), the Sony NEX-5N, the Panasonic GH2, and the Nikon D800
A quick review of this nice little camera, which packs a great image into its nearly-pocketable size
This camera can't load custom-built picture styles, but I managed to get a nice image using some not-very-common settings
Rated by the number of stops of DR that they get, with one set based on Portrait and one based on Neutral, and tested on the 5D3
High ISO shots from the 5D3 are amazingly clean: there's nearly no noise. That's in part thanks to noise reduction algorithms, and has a price: detail
Fellow Spaniard DSLR shooter and deep lensaholic Ignacio Sánchez lent me a bunch of interesting vintage lenses today, and I added them to my sharpness and bokeh tests
If we're going to end up subsampling our color information anyway, we might as well do it directly in the sensor, and get better DR out of it
ISO values don't mean the same on all cameras - here I show, using footage from Philip Bloom's Christmas 2011 shotout, how it varies on different models
Unhappy with all the previous options (like Technicolor CineStyle and Marvels Cine), I have created the Similaar suite of picture styles: Flaat 1 through 4
I just added a small section about macro photography

A simple chart that tells you which lenses work on which cameras (specially useful for vintage glass)
How sensor size and crop factor affect depth of field and field of view: some theory, and a quick test
Some sharpness and bokeh tests that show the kind of issues you'll find on a badly assembled vintage lens (it's a very common problem: check your lenses!!)
Testing sharpness on all my lenses (Canon, Tamron, Tokina, vintage Carl Zeiss Jena, vintage Leitz for Leica) with The One Dollar Resolution Chart
Summary - by aperture - in video mode
Some sharpness and color shift tests with my ND filters (Tiffen screw-in, LCW Fader ND, resin filters for the Cokin P system)
Bokeh tests, with all my lenses (Canon, Tamron, Tokina, vintage Carl Zeiss Jena, vintage Leitz for Leica)
A very relaxed day with a couple of friends - I think it's my best-looking flick so far
With only a handful of lenses, I run some additional tests to understand the relation between focal length, bokeh quality and bokeh quantity.
Some sharpness tests with my diffuser and polarizer filters (what they do, and how they affect image quality) (my ND filtersh have a specific section here)
Thoughts and tests on my journey to find the best picture style for my Canon DSLR - Initially I liked Technicolor CineStyle, but I'm using Flaat now
A collection of custom cropmarks that I created for Magic Lantern on my 550D (T2i), with different aspect ratios, markings and color schemes
A simple tool to help me setup my monitor at work: I want it to look nice, but I can't take my calibrator there, only play with brightness and contrast
An empirical test to check whether my eyes can see any detail beyond 1080p (2 megapixels). Download the video file and test your eyes too!
Some thoughts and empirical tests to try to shed some light on the neverending dispute of whether more megapixels means more noise
Quick and simple tool that calculates depth of field and field of view of a camera as a function of lens and camera settings - great for smartphones
