Another reader of ours, Frank Di Luzio, sent the below image that explains exactly why sensor dust is more visible at small apertures. While I have explained this phenomenon to some of our readers before (see the comment section), I have not had a chance to write a separate article with a proper illustration, demonstrating how aperture size affects the shape and size of dust particles. Thanks to our generous readers like Frank, I now do not have to do it, because the below illustration is perfect.
As camera manufacturers are continuing the megapixel race, with Sony releasing a bunch of 24 MP APS-C (1.5 crop-factor) cameras like Sony A77, A65 and NEX-7, and Nikon releasing a high resolution 36 MP Nikon D800, many of us photographers question the need for such a high resolution sensor. Some of us are happy while others are angry about these latest trends. Just when we thought companies like Nikon abandoned the megapixel race, instead of seeing other companies do the same, we now see Nikon back in the game with a new breed of product with a boatload of pixels. Why did Nikon all of a sudden decide to flip the game? Why does everyone seem to be going for more pixels rather than better low-light / high ISO performance? Does a high resolution sensor make sense? What are the true benefits of a high resolution sensor? In this article, I will provide my thoughts on what I think has happened with Nikon’s camera strategy, along with a few points on benefits of a high resolution sensor.
While the Nikon D800 has not officially been released yet, its specifications have been leaked for a while now, so our readers have been asking more and more questions about it. In this Nikon D4 vs D800 comparison, I will write about the rumored specifications of the D800 and compare it to the Nikon D4. While these cameras are for completely different needs and obviously are at difference price points, both are generating lots of interest from the Nikon community. Once the Nikon D800 is officially released and I have both cameras, I will provide much more detailed analysis of differences between these cameras, along with image samples and ISO comparisons. Please keep in mind that some of the D800 specifications below are pure speculation and might not match the actual specifications of the camera when it is released.
Many of the current Nikon D3s owners like me probably wonder about the differences between the new Nikon D4 and the now obsolete Nikon D3s DSLR cameras. While I do not yet have the Nikon D4 to do more in-depth side by side comparisons, I decided to write about differences in body design and specifications between the two. More details about the Nikon D4 will be published in my upcoming Nikon D4 review.
Nikon has just released the much anticipated Nikon D4 DSLR, a major update to the existing Nikon D3s camera that was released back in 2009. The Nikon D4 is Nikon’s flagship DSLR, designed specifically for sports, news, wildlife and event photography that require superb low-light capabilities. Due to the high resolution sensor of the Nikon D800, we might not see a Nikon D4x for landscape and fashion photography needs, but a Nikon D4s might follow in a couple of years.
Just a few days before Nikon D4 is announced at CES, I decided to write a review of the Nikon D3s DSLR that I have been shooting with for the past two plus years. I have been putting off writing the review for a while now, because I wanted to first review all the gear that I have been testing lately, while the gear I use every day for my photography has been just sitting at the end of my long “to-do” list. The Nikon D3s has received numerous awards, including “best product / camera” from various reputable organizations and websites. And it did for a reason – its image quality, high ISO performance, superb autofocus, fast speed and rich features make it a phenomenal camera – truly one of the best cameras in the world.
While the photography community is impatiently waiting for a Nikon D700 replacement announcement, I decided to write a review of the Nikon D700 DSLR that I have been shooting with for the past three years. Not sure why it took me so long to write a review of my favorite camera…I guess I focused so much on reviewing new lenses and cameras, that the gear I use every day for my photography has been just sitting at the end of my long “to-do” list. Within the next few weeks I am planning to temporarily reverse the list, start from the bottom and write about other gear that I currently use and used in the past and share my subjective opinion about it.
Like any manufactured product, Nikon’s products are also prone to quality assurance / quality control issues. While Nikon has a very extensive and comprehensive quality control process, some defective products can slip through and make it to the market. Other times, the pressure to increase the production output on Nikon’s manufacturing plants is so high, that the initial shipments of a newly introduced product can be defective or could have other problems not discovered during the initial testing of the product. Unless the defect is of physical nature, the latter is typically addressed through firmware updates later, which Nikon is pretty good about.
This is an in-depth review of the Nikon D5100 DSLR, based on my two month experience with the camera. Marketed as an upper-entry-level DSLR, the Nikon D5100 is a major upgrade to the older Nikon D5000. It has a larger and a more enhanced swivel LCD screen and the same remarkable sensor as the semi-professional Nikon D7000. In addition to the above changes, the Nikon D5100 also lost some weight, making it lighter and more compact than the Nikon D5000. In this review, I will provide a detailed analysis of the Nikon D5100 and compare it against the Nikon D3100, D5000, D90 and the current Nikon D7000 DSLRs.
I recently witnessed how a friend of mine got robbed by an online camera store called AjRichard based out of New York, USA when he purchased a Canon 5D Mark II. The camera was out of stock for a few weeks in every single local and online store he trusted and he could not wait any longer. That’s when he decided to expand his search and see if he could find an Internet store that had the 5D MKII in stock. He eventually ended up on Nextag.com looking at a list of merchants with “in stock” indicators. The top sellers all had very high ratings and he noticed that some of the sellers were advertising the 5D MKII at lower than the $2,500 “normal” rate that everybody else sells for. The top result was AjRichard.com and with over 1,000 reviews, 5 star rating and a “Trusted Seller” status, he decided to take the plunge and order the camera at just $2,350 – a really good deal he thought he was getting. The sad part is, he felt something was not right while making the purchase and still did it, thinking that his credit card company would protect him in case something went wrong. Next day, he got a call from AjRichard sales rep, who told him that camera battery and charger were not included in the $2,350 price and convinced him to buy those, along with some accessories he did not need. The order went up to $2,629 and he was promised free three day shipping. He needed the camera ASAP, so he agreed to complete the transaction and paid in full. Here is what his order looked like:
