dov makabaw 129 Posted May 28, 2015 Share Posted May 28, 2015 Have you checked your equipment on Cambridge in Colour. Show you the maximum f stop over which you will get diffraction. I found that for my old Nikon it was f11 but for my new Nikon it is f8. dov Link to post Share on other sites
Allan Bell 2,629 Posted May 28, 2015 Share Posted May 28, 2015 I have bookmarked "Cambridge in Colour". Naturally. Will have a look to see what they have to say. Allan Link to post Share on other sites
Christopher Holt 15 Posted June 2, 2015 Share Posted June 2, 2015 Many of my images on Alamy that I shot with a Canon 5D (mk I) and 24-105L were shot at f16. Maybe I should have kept that lens. But I'm all Sony mirrorless now anyway. Bill, I assume you've gained a weight/hassle advantage, but are the images comparable? Which model have you chosen? Chris Link to post Share on other sites
Bill Kuta 174 Posted June 2, 2015 Share Posted June 2, 2015 (edited) I sold off my 5D, 24-105, 70-200 etc just about two years ago. I was tired of the weight, the 12-megapixel was getting outmoded, and I decided that mirrorless had matured enough. Actually, that's why I sprung for the 5D in early 2006--I had decided that full-frame digital had matured enough in terms of pixel count and reasonable-enough price. So with the proceeds, I started accumulating:- Sony NEX-6 with kit lens- Sony 10-18mmthen later in 2013:- Sony a3000then in mid-2014:- Sony a6000 + 16-70mm (combo deal of $1300 at B&H)then late last year:- Sony 55-210mm (cheap unwarrantied on Amazon)Filter my remarks about these through the facts that I am rather part-time on photography, retired from another profession; I don't do studio/commercial/assignments, so I don't look for equipment to satisfy those needs; and I have nothing against Fuji XT-1, four-thirds, or any of the others.The a6000/16-70mm is my main camera, giving me the same focal range as the 5D/24-105mm, which suits my style. Are the images comparable? I would say comparable but different (only now at twice the pixels), in that a full-frame seems to give you a wider range of depth of field. No, I don't shoot at f16 with these cameras.I keep the 10-18mm on the a3000. The a3000 has a quirky set of feature compromises, but the price is very low and the 20-mp IQ is very high. I think it's a good match with that lens--the fiddliness of the a3000 doesn't matter as much with a very wide-angle, as it's unlikely I'll be shooting anything that moves much.The NEX-6 with kit lens stays in our car as a stealth walk-around camera. I also use it with the 55-210mm.Since the OP is about QC, let's talk about that, so that the thread is not totally highjacked. Since I started accumulating the Sonys, I've successfully submitted 770 images, from all the cameras and lenses, at many focal points. I've sold a few. They work for Alamy.I was happy where I was photographically in 2006 with the Canon full-frame, and I'm happy where I am now with the Sonys. I carry the a6000 and a3000 around in a smallish bag. Life is good.ps - I also picked up a Canon SL-1 along the way, mainly to use with an existing Canon 55-250 at the grandson's soccer games. Some shots from that camera have also made it onto Alamy.pps - Make that 781 images accepted from the new cameras--another small batch just approved.

John Mitchell 4,972 Posted June 2, 2015 Share Posted June 2, 2015 Bill, Mirrorless has definitely taken a load off my aging bones, and I'm happy about that. I had some QC problems with the NEX-6 at first because I wasn't used to the hybrid focusing system. Have had no problems since then. However, I do occasionally downsize images, probably more out of paranoia than necessity. As mentioned earlier, I've found that the lens modules developed by DxO (DxO OpticsPro) for the Sony e-mount lenses have greatly improved the look of my images. Even so, I still get the jitters every time I upload a new batch to Alamy. Link to post Share on other sites
Christopher Holt 15 Posted June 3, 2015 Share Posted June 3, 2015 Bill, many thanks for that reply - sounds like a true digital replacement for my Ricoh GR1 at last! Will have to try it myself. John, personally, I would still run them through Lightroom to get the preprocessing advantages. Chris Link to post Share on other sites
